3. Charging the COM400CC Batteries

When there are good batteries in the COMMUNICATOR and the power is on, the red

light above the power (PWR) button will be lit. This light only indicates the power is on.

It does not indicate how much power is left in the batteries. As the batteries weaken

during routine use, you will hear a repeating beep in the earpiece, indicating the

batteries need to be replaced. When this happens, remove the battery from the

Communicator as shown in Figure 6. Place both batteries in the AC900 Battery

Charger for recharging. Refer to Figures 7 through 9. Replace the batteries in the

Communicator with fresh, fully charged batteries. Typical battery life with normal use is

8 to 10 hours.

CAUTION: To prevent damage, turn Communicator OFF before removing or

installing batteries.

Installing and Removing Communicator Batteries:

Charging COM400CC Batteries in the AC900 Battery Charger:

Place up to four COM400CC batteries in the charger for charging at a time. See Figure 7.

The red Charging light, adjacent to a battery being charged will go on and remain on

while the battery is charging. Routine battery charging takes up to 3 hours.

NOTE: The COM400CC uses “smart batteries.” That means each battery maintains a history of the

number of times it has been charged. The

AC900 Battery Charger reads and updates

this history each time a battery is charged.

This information is used to automa-tically

initiate conditioning cycles, which improve the

battery’s performance and prolong its life. A

conditioning cycle consists of a complete

discharge before a battery is charged. This

happens each time the battery history

indicates it has been charged 10 times since

the last conditioning cycle. While a battery is

discharging, the red Charging light next to it

will blink on and off at 2-second intervals.

The conditioning cycle takes up to 6 hours.
