bent 2-way radio at the repair center

this is not good at all

Bent CP200d board bent CP200d radio board

In the radio repair industry we have seen many ways end-users damage their radios. One of the more common types of portable radio damage is compression or crush damage. When this happens the component board, which is very rigid, can become bent. How does this happen? Usually it is a from the user sitting on the radio after it has been placed in their back pocket or in the seat of a vehicle.There are a multitude of problems that can be caused when your component board gets bent in this way, and none of them are good.

Usually the exterior house of the radio miraculously can bounce back into shape follow a squeeze (unless it is of the extreme nature). What you can’t see is the effect it has had on the board inside. Many times the radio user will not realize the component board has been damaged.

The Motorola radio pictured arrived from Mississippi with only exterior scuffs, and no additional notes. The real damage wasn’t seen until the technician had opened the CP200d radio. As you can see in the pictures, the metal shields were dented in, and the green component board was warped. Not seen in these photos, underneath the shields there are likely components which have popped off the board. The layers of the board and traces are likely cracked. Unfortunately in a case such as this the damage is fatal. The radio had to be deemed non-repairable.

At the radio repair center we’ve seen radios that have been driven over by a truck be repairable. We rely on our highly skilled technicians to assess each radio and determine if it can be repaired or needs to be replaced. If you have a radio you believe to have compression damage, go ahead and send it in the the radio repair center. As radios have became smaller we see more compression damage. Some damage is as simple as the user placing the radio in their back pocket and sitting on it. Other damage is more serious and caused by machinery or vehicles.

crush damaged 2-way radio batteries

Another area of concern would be the battery that was on the radio at the time the crush damage happened. The cells in the battery could be come unstable and be a hazard. Much like the radio housing the battery’s exterior may not show the damage within. If the compression was enough to deem the radio non-repairable, the battery should also be retired to recycling. (Side note: Most Lowe’s, Home Depot, and Best Buy stores have battery recycling centers near the front of the store.)

If you find yourself with a compression/crush damaged radio, we’ll be happy to take a look at it and determine if it is repairable. Radio repair is generally around one third the cost of new.

someone ran over my radio

It happens more often than you might think… an employee comes in to tell the boss “someone ran over my radio”. It is not something a business owner or manager wants to hear. The radio repair center compression damaged radios in all shapes and sizes (Motorola, Kenwood, Vertex and others). Some are repairable, while others are not.

Repairability might depend on whether the radio was on a solid surface, or something simple like dirt or mud. It also depends on the rigidness of the housing. Larger radios are generally more forgiving than small radios, simply because there is more space between the component board and the exterior housing.

What to do if your radio gets ran over:

1) Turn off the radio. Look for physical signs of damage.
2) Be especially watchful of any battery which has been squeezed or crushed. (See the previous blog post about this.) If the battery is obviously damaged get rid of it in hazardous waste. If you are uncertain, send it in with the radio.

The good news is many business grade radios survive being driven over by a loader or truck. All is not necessarily lost. If your radio is damaged get it in to the radio repair center right away. Let us know it has been squeezed or crushed. We will do what we can to get it repaired and back to you right away.

Here at Delmmar Communications our nationwide 2-way radio repair center can assess your damaged radio and determine if it can be brought back to factory spec. The cost of radio repair is generally less than half the cost of a new radio. Give us a call, 800-872-2627.

bulging, smoking, flaming batteries

Bulging 2-way radio battery

Scary even when it’s not Halloween!

What happens when your radio’s battery becomes a fire hazard? How does this happen? Physical damage, over charging, defective battery… these can all be potential causes.

This bulging DTR series battery is from a DTR650 2-way radio that came into Delmmar’s 2-way radio repair center for repair. Our check-in crew quickly spotted the bulge and placed the battery in a secure fire resistant location.

During a repair the radio and accompanying accessories are assessed by a qualified technician. All common failure parts, along with any other necessary parts are replaced. With this radio a phone call was made before beginning the repair. The customer chose to have their DTR650 radio repaired under the flat rate repair and purchase a new battery to replace this bulging one. Bulgy has been disposed of in hazardous waste.

In the news recently there has been a lot of talk about electronics devices catching fire on planes. An educated guess would be the battery in the device was damaged or poor workmanship. It could have been physical or liquid damage, overcharging, poor manufacturing, or the effects of the change in air pressure in the cabin. While we have not heard of any incidents involving 2-way radios (which have restrictions when taken on a plane), users should always use wisdom whether in the air or on the ground.

There are dozens of youtube videos showing these types of batteries in flames once they are abused, overcharged, wet or mistreated. Short story: If your radio battery bulges, or shows any sign of puncture/damage DO NOT use it.

Delmmar Communications‘ advice: For your two-way radio choose a fresh good name brand battery from a reputable radio dealer. Choose good quality Li-Ion or NiMH batteries instead of Li-Polymer. If you have questions give us a call, 800-872-2627.

do you care about battery dates?

GOT STATIC? GOT POOR TRANSMIT?

Using an old battery on your radio can cause you problems, including poor or intermittent transmit, a battery that no long last the full day, lots of static or white noise, poorly functioning add-on audio devices, and more. Continual use of an old or bad battery can eventually cause wear and tear to the radio itself, resulting in the need for repair.

The life expectancy of the average rechargeable battery used in 2-way radios or other devices is 2 years. This includes your rechargeable flashlight as well as your portable radio.

How can you tell the age of your battery?
Nearly every manufacturer of a rechargeable battery marks the battery with a date code representing the date of manufacture. Sometimes these date codes are hidden in plain sight. You might feel like you need a secret decoder ring to break the code. Motorola is no different than most manufacturers, their batteries and accessories are marked with manufacturing codes.

Motorola batteries follow a very simple date code system. You will find a 3- or 4-digit number on the battery label (or embossed in the plastic of the battery itself). Use the example 1611, the first two digits are the year, and the next two digits are the week of the year. The battery shown is dated 2016 the 11th week.
If you have a 3-digit code the first number is the year. 611 would be either 2016 or 2006. (You can usually tell by the appearance of the battery if it is 10 years or more old.)

Next time you have a poorly functioning radio check your battery date code. Maybe you simply need to replace your battery.

Battery tips:

Clean your battery contacts on your radio and charger periodically with a pencil eraser to remove any film or debris. This will allow your radio to make better contact on the charger. (Never use chemicals or a sharp object to clean contacts.)
Always have your radio turned off when placed on the charger, and if in an emergency you must have a radio turned on when on the charger, never ever transmit while charging. This can burn out components in your radio causing the need for repair.
If you feel you have an old, bad, or poorly functioning battery, try trading batteries with a known good radio and see if the problem is solved. You may simply need to replace your old battery.
The shelf life of a battery which has never been charged (initialized) is supposed to be indefinite. If you store new batteries before you use them, mark them with the date you initially charged the battery. This will give you a better idea on your 2 year life expectancy.
When initially charging a battery that has been in the cold or stored for a period of time before use it may take 2-3 charge cycles for the battery to successfully take that first charge. If you charger is blinking when it usually doesn’t, leave the battery on the charger and let it blink a few hours, even try again the next day doing the same thing. The battery will usually wake up, charge and be fine.
Beware of aftermarket batteries from less than reputable sources. We’ve seen or tried them all. We do offer a good aftermarket battery for most models if you are looking for such a battery.
Dispose of all old batteries in hazardous waste. Most big box stores have handy recycling bins where you can deposit your old batteries for recycling.

What are you waiting on? Go check your date codes! If you have questions give us a call here at Delmmar Communications, 800-872-2627. We are always happy to help.

radio vs cell continued…

We often are asked by friends, family and clients about the status of 2-way radio in a world where everyone seems to be carrying their own personal communications device, a cell phone. Here are some thoughts of those in this industry concerning this subject.

Most people would admit they could not function without their smart phone, the computer attached to your hip.

But in reality, as a communications device, a cell phone is still a device for making a phone call to another person. You dial a number, let it ring, wait for an answer, hope to talk to the person you are calling, possibly leaving a voice message. The process takes at least a minute of your time or more just to connect. And following this routine, you may end up having a conversation for several minutes.

When using a two-way radio you simply press the push-to-talk (PTT) button and instantly speak to your group (or one-to-one depending on your radio system). You can give a brief message or instruction, receive an immediate response and finish your task accordingly. The entire process typically takes a few seconds. It is fast and efficient, saving time and money. In the realm of public safety and businesses such as construction, it can save lives. In addition, radios are highly effective in high noise environments, built rugged for long-term use, offer an intuitive one-touch user interface, and feature a battery designed to do a full day’s work.

Nearly all business models of two-way radios are repairable and have replacement battery packs available. The life expectancy of a two-way radios is up to 10 years, with many exceeding this mark. Computing the cost of purchasing a typical business 2-way radio (Motorola CP200d) over 10 years including replacement batteries every two years and 1-2 repairs, it would calculate to under $12/month to own/operate the radio. Much less than the overall cost of cellular for the same time period.

Cellular devices are by nature fragile. The majority are too lightweight for work environments. Battery packs are often non-replaceable. If you talk to those in the cellular industry, you will find the life expectancy of a phone is about two years. At the 2-year mark, the cell carriers are ready to make a deal with you where you can get the next model “free” or inexpensively to keep you as a client. The industry is reliant upon the monthly fees we all pay. We’ll let you do the math on what a maintaining a cell phone will cost you over the course of 10 years.

Radio communication is instantaneous with the simple use of a PTT button. The person needing information receives it quickly. Requests for assistance are heard by everyone monitoring the frequency. This is essential in many industries and especially in public safety. Radios designed for public safety can also have other features such as an emergency button or a mandown feature where the radio will notify dispatch of an officer who is no longer vertical. In construction when giving instructions to a crane operator PTT radio technology is the quickest form of communication. Think about restaurant hostesses or retail clerks communicating with others on their team. This type of communication is done more efficiently using a radio versus a cell phone. It would be hard to imagine the public safety or business world without 2-way radios.

And up to now we haven’t mentioned the downside of using a cellular device instead of a radio, things such as surfing the web, playing games, making personal calls, just aren’t a problem when businesses use two-way radios for their onsite communications. So when choosing between using your smart phone and 2-way radios, you can see where the two devices differ both in features and overall long term cost. Both have their place where they can work to the best advantage. It’s up to you as a business person to choose your communications device wisely.

What will the future bring… expect a new generation of radios with smartphone capabilities. Stay tuned.

early indications of Spring…

Greenhouse Plants Our customers in the nursery and greenhouse business are starting to prepare for Spring. 2-way radios which had been set aside from last season are beginning to arrive at the radio repair center to be tuned up and repaired for the busy season ahead.

Many in the growing industry use push-to-talk radio technology instead of cellular for on-site communications. A variety of reasons include: two-way radios are dedicated primarily to voice capabilities, which support immediate person-to-person and group communications; and while smart phones provide many features and Apps, it is the simplicity of two-way radio that makes it attractive for situations where simple communication is important. Simply push the button and talk! It’s easy with no learning curve, or games and Apps to get distracted.

Two-way radios are designed to be rugged, and take the punishment of a 40-hour work week. Nearly all models are repairable and have replaceable batteries. This is why many nursery and greenhouse owners rely on basic push-to-talk technology to save the steps of many workers while providing communication throughout their facilities. One of our growers explained one increased productivity benefit this way, “You don’t have to worry about an employee calling or texting his girlfriend on his radio… unless she is an employee too.” Guess that can be listed as another side benefit of 2-way.

This is your reminder to check your radios over before the busy season and get them in for repair if needed.

Also, now would be a great time to replace batteries. You can order directly from eradiostore.com, or give us a call here at Delmmar Communications, 800-872-2627. We’d be happy to look up your radio model and tell you what battery options are available.

new year, new digital radio…

The newest radio to come along is the Motorola CP200d. It is part of the widely touted MOTOTRBO digital/analog line of radios. Trbo radios are a great transitional radio into the digital world. You can add them into your fleet as an analog radio to match your existing radios, and then one day when you are ready they can be upgraded or reprogrammed to be digital. Or even be digital or analog on a per channel basis. Much like the existing Motorola CP200 radio, the “d” model is available in either VHF or UHF and has 16 channels.

The CP200d is available from Motorola Channel Partners (a fancy way of saying authorized dealers) in two versions:
1. Analog only model, upgradeable later to digital (call for upgrade cost).
2. Digital/Analog model. Straight out of the box the radio has both features.

The advantages of digital are much like you would have experience when changing to a digital cellphone a few years ago, 40% longer battery life, clearer transmissions, and a small to moderate increase in range. Good news is the radio uses the same batteries and chargers as the standard CP200. Some audio accessories will be backwards compatible such as the PMMN4013 remote speaker mic. Many other audio accessories are available for the digital models. Watch for the digital symbol to be on the accessory to insure good functionality with the digital radio.

The analog model is priced pretty much the same as the standard longstanding CP200 radio. The digital version of the CP200d is $50 higher. Also new on the scene are the CM200d, CM300d, and XPR2500d mobiles.

The standard CP200 you have known for several years is no longer available. We will continue to repair this model at the radio repair center as long as parts are available.

If you have questions give us a call here at Delmmar Communciations, 800-872-2627. We are always happy to help.

Have a great 2014!

about CP200d batteries

The Motorola CP200d radio has come with 3 different battery types over the past few years. The CP200, CP200-XLS, and newer digital CP200d come with the NNTN4497 Li-Ion 2250 mAH battery. You can expect this battery to give you a good full work day of 12-14 hours. Life expectancy is approx. 18-24 months. Li-Ion is less likely to suffer from the memory effect which is common to the NiCd chemistry of batteries. It is the preference battery by most users.

The current NNTN4497 Li-Ion battery and the earlier NNTN4851 NiMH batteries need to use the fast rate charger to properly charge their battery packs. The fast rate charger is easy to differentiate from the trickle charger. The fast rate charging tray has outlines of several batteries depicted on the bottom of it, while the trickle charger has only one outline of a battery.

Some radio users received the trickle (slow rate) charger with their early model CP200 or CP150 radios. This slow charger is only useful for charging one chemistry of battery, the NiCd NNTN4496. Older model CP200 radios can be upgraded to use the more current Li-Ion NNTN4497 battery with a fast rate charger with no modification needed to the radio. You would simply need to purchase the Li-Ion battery and a fast rate charger. (The slow rate charger is no longer available. But not to worry, the NNTN4496 NiCd battery will charge just fine on the newer fast rate charger.)

Very similar to the original CP200 is a nearly identical PR400 radio. The PR400 radio uses the same accessories. When new the PR400 portable came with a slim Li-Ion 1600 mAH battery NNTN4970, which will also fit the CP200 radio.

The single unit and multi-unit fast rate drop-in chargers for the CP200d radios will accommodate any of the above mentioned battery types. The charger features a convenient insert which can be removed and turned around to fit the size of battery being used. This same insert has vertical rails which guide the battery into place, and will hold a battery alone or a battery attached to a radio in place during charging.

TIP: Always have your radio turned off when on the charger. And only charge your battery when it is 80% or more depleted. This will help you achieve a long full life from your batteries.

Most batteries will last approx. 2 years (or 3 years if you treat them really well). Use the manufacturers date code to determine the age of your battery. On a Motorola brand battery the first digit(s) are the year and the last two digits are the week of the year. Example: 1611 would be 2016, the 11th week, and 611 could also be the same date (or if very old it could be 2006, the 11th week). Keep in mind using an old battery for an extended period of time can eventually lead to the radio making a trip to the radio repair center. It is wise to replace your 2-way radio batteries every 2-3 years. This will help keep your radio in tip top shape.

ahh the life (expectancy)

Signs of a bad, defective, or aged battery include constant or intermittent static, a shorter work day, and intermittent or poor transmit. Transmit problems are an early indicator of a old or bad battery. It is simple, it takes more energy to transmit than to receive. So if you have a radio that receives perfectly, but is iffy on transmit, check your battery.

So then the question arises… What happens if I continue to use the old battery? Just like any home appliance operating on low voltage, your radio will eventually have failures associated with the brown out. Then the simple need for a replacement battery turns into a battery + radio repair. As you can see, it would be much cheaper and wiser to replace the old battery when needed.

How do you know the age of a battery?

On Motorola brand batteries you will find either a 3-digit code or 4-digit code on the label of the battery or embossed in the plastic of the battery itself. (See above photo for an example.) The first number on the 3-digit code represent the year of manufacture, the next two numbers are the week of the year. Example: 611 would be 2016 (or heaven-forbid 2006) the 11th week of the year. The newer 4-digit date codes are easier, 1611 would be 2016, the 11th week.

If you have difficulty determining the age of a battery, give us a call here at Delmmar Communications, 800-872-2627. We are always happy to help.

heavy radio use

It’s that time of year when radios are going to be put into heavy use

Many businesses are now in their busiest season, while others are just gearing up, 2-way radios are getting heavy use. Now is a good time to assess what you have, checking over your radios, batteries, chargers, etc.

Do you have radios that are in need of battery replacement or maintenance? A quick check of the battery and charging system can save many headaches done the road. You probably don’t need reminded, but something as simple as cleaning your battery contacts with a pencil eraser can improve your chargers’ efficiency.

TIPS:

Swapping a known-good battery into a troubled radio can let you know if you have a battery or charging problem. Another piece of advice is to check your battery date codes. The life expectancy of a NiCd battery is 18-24 months, NiMH and Li-Ion are around 14-18 months. If you have good charging habits and treat your battery well, you may get up to 3 years. At the end of the battery’s life you will start to experience problems with the radio such as static, short business day, no or intermittent transmit. If you use an old battery long enough, it will eventually begin to harm the radio, resulting in a need for repair. Simply replacing an old battery would be about half the cost of a radio repair. Our advice… don’t ignore battery date codes.

Chargers take their share of punishment. It is wise to assess your chargers when you are check your batteries. Look in the charger cup, do you see dirt and debris? If so, clean it out with a soft cloth, followed by gently cleaning the charge contacts with a pencil eraser. Check your wall transformer, they are known to burnout much a like a light bulb. When replacing charger transformers keep in mind they are not mix-n-match, you must use the appropriate transformer for the charging tray. Replacement chargers and individual components are usually available for most radio models.

Ever think your radios’ range is getting poorer? Check your antenna. If you can see copper coils when you bend the antenna, or if the top cap is missing, you need to replace the antenna. Use the correct antenna for the radio. The original antenna which came with the radio was designed to work with the radio. Swapping antennas can cause range problems, or result in the need for repair. Some model radios have stubby antennas available, keep in mind these can reduce your range by up to 2/3s. If most of your work is nearby, they may be a good option. However, if you do a lot of work at the edge of your full range, stay away from stubby antennas.

In the event, none of these tips seem to alleviate your radio issues, your radio may be in need of the radio repair center. We have a radio repair form that is easy to fill out. Just put it the box with the radio and we will get the unit repaired and back home to you. We offer a 5-7 day turnaround on most models.
