superglue + radio = no

Superglued Motorola CP200

Superglued Motorola CP200 arriving at the Radio Repair Facility.

Sometimes a well meaning radio user will use a superglue like adhesive to glue items to their radio, or even attempt to fix an internal component. As nice as we can, we’d like to say… please do not do this. Why? you might ask… When a radio comes to the radio repair center for repair the electronics technician repairing the radio utilizes the radio’s accessory jack to connect his test equipment. If glue has been used to attach the remote mic or other audio device to the accessory jack then the two must be broken apart. This generally causes damage to both devices. This can be an unnecessary expense to the customer. As you can see in the picture both the radio housing and the accessory’s plug were damaged getting the two apart.

On the CP200 style radio a simple solution is to use an audio accessory retainer. This is a device that screws onto the side of the radio to hold the plug in place. On HT750 and other HT Pro Series radios this screw on device is built into the accessories. On many other radio models which do not have this feature the accessory’s plug should fit tightly enough in the jack to keep the plug in place. (If not your radio likely needs a new jack.)

Just say “NO”

Internally you should never use glue or solvents on the component board of the radio. Superglue-like adhesives are an explosive/fire danger to a technician with a soldering iron. When touched with a hot iron components can actually be blown off the board causing a danger to the eyes, face and hands of the repair technician. Our techs are trained to watch for these types of substances, however, with the substance being clear it is sometimes hard to detect. So please keep this in mind the next time you or a well-intentioned employee thinks to glue something to a radio. Just say no! It will save you an unnecessary expense during your radio repair.

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

Motorola NNTN4497 batteryThe 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.

Motorola battery date codeMost 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)

2-way radio batteriesSigns 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.Motorola battery date code

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.

tidy up workspace

It seems offices become more cramped and cluttered over time. I find we start to surround ourselves with items we might need someday versus the items we truly need for work. Periodically it is necessary to take a good look at the space and declutter, getting rid of items which are obsolete, seldom/never used, or items which can be stored elsewhere.Motorola Multi-Unit Charger

One nifty way to tidy up your radio chargers is a multi-unit charger. When you have multiple single unit chargers and all their cords running amuck, you can take up some space, not to mention many electrical outlets. Most radio models have multi-unit chargers available. These gang chargers typically hold up to 6 radios, and consist of a main unit with 6 radio cups, and a power supply. A variety of options are available, everything from a basic model to the fancier battery maintenance systems with digital displays.

Motorola has a smart energy system charging system named Impres

Motorola has a smart energy system charging system named Impres which It’s the ultimate in battery recharging. When coupled with the Impres batteries the charger will keep track of each individual battery and automatically condition the battery when needed. This adds to the length of time a battery will last, saving you time and money.

Now would be a great time to tidy up your workspace and save money on the gang charger you need. If you have questions about which gang charger would go with your radios 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 Motorola Impres Batteriesor 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.Motorola battery date code

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.

more tips on better range

2-Way Radio CustomerHere at the radio repair center we get many questions about radio range (talk distance). Typically a handheld business radio will do 2 miles line-of-sight or as far as the radio can see. Several factors interfere with range, including but not limited to: curvature of the Earth, obstacles, height and placement of antenna, position of the radio, and using the correct antenna for the radio.
Range tips:

  • 1) Holding the radio upright with the antenna straight up gives you the best range. Tilting to the side, as if talking on the phone, will reduce the range by up to 2/3s. This will cause transmissions to drop out, or be very staticky. Just remember: Perpendicular to the ground is best!
  • 2) The body fluid of the person wearing the radio can absorb part of the range.  If you’re a little bit round in the middle, your radio will not work as well as your pencil-thin co-worker. You can compensate by wearing the radio higher your body. Maybe in a shirt pocket or with a chest pouch. Height and placement of antenna determines range.
  • 3) Use a good quality fully charged battery. It takes more energy to transmit than to receive. Using a good battery will do wonders to clear up static, making your transmissions clear.
  • 4) Use the appropriate antenna for your radio. While stubby (short) antennas may be available for your radio model, keep in mind these will significantly reduce range. If you are working in a close proximity, they may work wonderfully. However, if you are expecting to transmit a long distance, go back to the original standard length antenna.
  • 5) Check your antenna for damage. If you can bend the antenna and see the coils or if the top cap is gone, it is time to replace the antenna. This may do wonders for your range.
  • 6) Get your radio tuned up. Electronic components inside your radio age over time and the radio will not function as well as it did new. Getting your radio tuned and realigned will bring it back to factory spec, or as close as one can get with an older radio.

radio range

Radio Repair CenterHere at the radio repair center we occasionally get questions about the range of a 2-way radio. Below are some simple answers to basic two-way radio range questions:

Portable radios generally will talk radio-to-radio, line-of-sight up to 2 miles. Once you start putting obstacles between the radios you will shorten your range. Even the body fluid of the person wearing the radio on their hip will absorb some of the range. Higher wattage radios will have a slight increase in range and a significant increase in clarity of transmission on the outer fringes of your range.

Mobile radios, such as those mounted in vehicles, will generally talk “radio-to-radio” 8-10 miles depending upon the obstacles and the terrain.

Base stations will generally talk approx. 8-12 miles. (referencing a simple base station where you use a mobile radio, power supply and outside antenna, aka a control station.)Contrary to popular belief wattage does not determine distance. Antenna height and placement determines distance.

  • Increasing Range:
  • 1) Hold your radio perpendicular to the ground, not slanted like you would hold a phone. This problem alone could decrease your range 30-50%.
  • 2) Don’t shout CB-style, shouting reduces talk-range on industrial-type radios.
  • 3) Be certain you are using a good, fully-charged battery.
  • 4) Check your antenna. Any exposed copper coil or weather checks which expose the coil when bending are a sign your antenna needs replaced. Also, keep in mind, use of a stubby antenna will reduce your range. The best antenna for a radio is generally the standard antenna it came with.
  • 5) And the technicians in the shop will tell you… have your radios serviced every two-three years to maintain peak performance.

Looking for even more range?

You might be in the market for a repeater, or have need to connect with a local repeater or trunking system which is already in place. But first, try bringing your radios to optimum range by following the above tips.
