CAUTION: Use only RITRON-supplied chargers; using other chargers may cause fire or

explosion, or otherwise damage the radio.

CHARGING

The JMX “D-Series” radio is powered by a rechargeable battery pack. Because the battery

pack loses its charge during storage and shipment, fully charge it before first use. To

ensure peak radio performance for the next day, charge the battery overnight after each

day of use. It completely charges in about ten hours.

TO CHARGE THE BATTERY WITH A RITRON CUBE CHARGER

Plug the charger cord into the charge jack (marked “CHG”) on top of the radio. Then plug

the cube into a 110 VAC outlet. The green lamp lights while the battery is charging, and

should go out only when the cube or cord is unplugged.

TO CHARGE THE BATTERY WITH A RITRON DROP-IN CHARGER

Two charger contacts, visible through the radio case bottom, permit charging the battery

with an optional Ritron drop-in charger. The battery pack may be either removed from the

radio case for charging, or charged inside the radio case.

Each drop-in charger comes with a spacer to permit charging a “spare” battery while the

radio is being used.

To use the drop-in charger, plug it into a 110 VAC outlet. Set either the radio with the

battery installed, or only the battery with the battery spacer, into the charger. Refer to the

illustration in OPTIONAL CHARGING ACCESSORIES on the previous page. Each battery

contact must rest on a charger contact pin.

NOTE:

Battery pack life averages one year. Follow these guidelines to maximize service life:

• CONDITION battery packs once a month as directed in Battery Maintenance &

Conditioning, at right.

• CONDITION batteries that are run down.

• CHARGE batteries for 16 hours before storage, and for 16 hours once a month

thereafter.

• DO NOT overcharge batteries. Unplug the cube charger after 16 hours to avoid

overcharging.

• DO NOT charge batteries in temperatures colder than about 45°F. Charging batteries in

temperatures above 95°C does not harm them, but can reduce charge capacity.

BATTERY MAINTENANCE & CONDITIONING

Due to the extended run time of the JMX “D-Series” radios,

some users may never fully discharge the battery pack during

normal use. Achieve maximum battery life by fully discharging

the battery periodically to condition it.

After exposing the battery pack to many cycles of not fully

discharging it before recharging, the radio may exhibit reduced

battery capacity. This reduced capacity is evident when, after

several hours of use, battery voltage drops while the radio is

transmitting, causing the radio to emit a low battery warning

tone.

Condition battery packs by the following procedure as either a

preventive measure, or if you suspect reduced capacity:

TO CONDITION THE BATTERY PACK:

1. Use your radio throughout a normal work day without

charging.

2. • Press and hold the On / Volume Up and Volume Down /

Off buttons simultaneously for 8 seconds to place the

radio in “no squelch” mode.

• Release both buttons when you hear the radio beep

rapidly; it will then emit a loud “rushing” noise. Press On /

Volume Up to maximize this noise.

3. Put the radio away in a secure place (possibly a desk

drawer), where nothing can press against the buttons to

accidentally turn it off or cause it to transmit. Allow the radio

to run until it shuts off when the battery is completely

discharged. A typical battery pack may require up to 8 hours

to completely discharge.

4. When the radio has shut off, charge it overnight for 12-14

hours. The battery will be ready for use with renewed

capacity.

NOTE: A new battery must be charged and discharged several

times before it can reach its maximum charge capacity.
