Range

Handheld radios generally will talk "radio-to-radio", "line-of-sight" up to 2 miles. Once you start putting obstacles in 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. 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 by up to 75%.
2) Height and placement of your antenna determines range. Simply placing your radio somewhere higher will solve many range issues, along with facing the direction you are talking.
3) Don't shout CB-style, shouting reduces talk-range on industrial-type radios.
4) Check your batteries. Old or defective batteries can cause intermittent or no transmit. Your radio will appear to receive fine, but transmit is limited. (See battery life category below.)
5) Have your radios serviced every two years to maintain peak performance. It is not uncommon for radios to lose some frequency alignment and wattage as they age.

VHF vs. UHF

In many business settings you can use either VHF or UHF with success.

VHF: Especially good for people who work somewhat line-of-sight or outdoors. VHF gets around rocks, dirt, hills and trees well and can also be used in many indoor situations.

UHF: While VHF and UHF will both operate line-of-sight up to 2 miles, UHF (450mAH range) gets in and around metal better and even has a better metal punching capability. It also works well in and around concrete structures.

If you are satisfied with what you have there is no reason to change. On the other hand, if you are having communications problems you may want to change frequency bands.

Battery Life & Charging

Rechargeable NiCd batteries have an average lifespan of 18 to 24 months. NiMH batteries have a life span of 12-18 months and are less prone to memory development.

Trickle charging (8-12 hrs.) is better for the life of your NiCd battery than regular use of a fast-rate charger. Limit fast charging to those times you really need it. If you can't run your batteries down completely before charging, do so at least once a month, followed by trickle charging. This will extend the life of your NiCd battery. Note: NiMH and Li-Ion batteries require fast-rate chargers.

When using wall-plug style chargers, wipe off the plug before inserting it into your radio. Many radios come to our service center with debris in the charge jack, which can cause your radio to short out. Also be aware that chargers do wear out, much like a light bulb. If the light on your wall-plug style charger does not come on when plugged into the radio or it blinks you need to replace the charger. On drop-in charger models check your charging trays and the bottom of your radio for dirt and debris.

How you care for your batteries dictates how long they will last. To extend the life of your batteries, try to run them all the way down before fully recharging them.

Do not remove the plastic coating from your batteries. This ruins your battery pack and also voids the warranty.

Recycling

NiCd, NiMH and Li-Ion batteries must be recycled or disposed of properly and cannot be dumped in landfills or incinerators. The EPA classifies used batteries as hazardous waste. Look for your local recycling program or call Delmmar at 800-872-2627 and we will help you with disposal information.

HOW TO: You can ship used Motorola 2-way radios, cellphones and (radio or cellphone) batteries to Delmmar for recycling. Clearly mark it is "FOR RECYCLING".
RADIOS:
Motorola has established a take-back recycling program to responsibly dispose of used Motorola radio equipment.
BATTERIES: Motorola partnered with RBRC accepts rechargeable radio/cellphone batteries for recycling.

Delmmar participates in all these programs. Join us, be responsible, recycle!

Radio Lifetime

You can expect most low-end handheld radios to last you up to 5 years. On a basic radio the cost works out to be between 17¢ and 37¢ a day. The high-tier radios ($500 and up) are engineered to be in use up to 10 years.. You can extend the life of your radio by keeping it free from moisture and dust. To keep it in peak operating condition you should have it retuned by a qualified technician every two years.

Wet Radio

Employees are sometimes reluctant to let you know they have dunked a radio. Let them know upfront, before the situation occurs, that time is of the essence when it comes to a wet radio.

Exposure to water can destroy your radio. If your radio gets submerged you need to get the water out of it ASAP, otherwise the circuit board will be ruined. Don't hesitate, corrosion takes over very quickly! Consider anything you do is a "last ditch effort" to save your radio. Remove the battery pack from the wet radio. If the battery pack is wet, get rid of it. Dry the radio thoroughly using a fan or blow dryer. Then get the unit into a service facility as soon as possible. Let them know it has been dunked.

Consider keeping an EVAP Rescue Pouch in your office. It is an inexpensive way to possibly save your wet radio or phone.

Refurbishing

As with any electronic device, from the moment you turn on your new radio it begins to age. As it ages the radio comes out of alignment. A qualified technician is able to check your radio for weak or worn out components and align the frequency for a lot less than the price of a new unit. It is best to send the radios to the service shop for retuning every two years or as problems arise.
