3. Charging the COM900CC 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 “Low battery” in the earpiece, indicating the batteries

need to be replaced. When this happens, remove both batteries 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:

Figure 6. Remove and replace Communicator battery

Charging COM900CC Batteries in the AC900 Battery Charger:

Place up to four COM900CC 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 COM900CC 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 automatically 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

Figure 7. Inserting a battery into

the AC900 Battery Charger

hours.

Page 8

When a battery is fully charged and ready for use, its red “Charging” light will go off and the green “Ready” light next to it will go on.

Figure 8. Battery charging indicator lights

CAUTION: Do not remove batteries from the charger until the green READY light

is lit, or the charger will reset and the charge cycle will begin again.

To remove a fully charged battery from the battery charger, push the battery from the end near the status lights.

Store fully charged batteries in the storage ports on the right side of charger until you need them, as shown in Figure 9.

Charging COM900CC batteries in the AC910 Battery Charger:

Figure 10.

COM900CC battery charging in the AC910 Battery Charger

Place up to four COM900CC batteries in the charger for charging at a time. The red

Charging light, adjacent to a battery being charged will blink for a few seconds when the

battery is placed in the charger, then will go on and remain on while the battery is charging.

NOTE: The COM900CC uses “smart batteries.” That means each battery will retain

charging information that will cause it to automatically discharge completely before

being recharged, every tenth time it is placed in the charger. This will improve the

battery’s performance and life. While a battery is discharging, its red Charging light will

blink on and off at 2 second intervals.

When the battery is fully charged and ready for use, the red light will go off and the

green Ready light adjacent to the battery will go on.

To remove fully charged batteries from the battery charger, push the battery from the

end near the status lights. Store fully charged batteries in the storage ports until you

need them.

B. Speed-Team Drive-Thru Operation

Speed team operation is used during high-volume times. Placing the speed-team button on the base station in the ON position will disable the speaker and microphone in the speaker post or menu board, and disable the vehicle-alert tone. An order taker wearing a Communicator relays orders from outside into the store using the “B” channel.

C. Remote Display Operation

One or more R30 Remote Displays may be used with your System 900. Each remote display was set up by the installer to show the amount of time the current car has been at the menu board, speaker post or service window. A remote display shows the time for one location only. It begins counting when the car arrives and stops when the car leaves. The remote displays will only display time. They will not store or record information.

D. Message Repeater Operation and Setup

To record messages on the System 900 internal message repeater, press the MESSAGE REPEATER button IN on the base station and do the following.

After a new message has been recorded, or after the base station has lost and regained power, any message to the menu board will always be heard in the Communicator headset the first three times it plays.

To change the message repeater setup, locate and set the S8 and S10 DIP switches at the

bottom of the System 900 Base Station audio circuit board. Refer to the S8 AND S10 DIP SWITCH FUNCTIONS tables to the right for S8 and S10 switch functions.

If a System 30 Timer is installed with the System 900, the timer alert output can be used to trigger tones in the headset or to cause a message to be played. Set S8 and/or S10, switch #5 to OFF for an alert tone (triple beep), which will be heard only in headsets, or to ON for recorded messages to be heard through selected speakers and headsets.

If a System 900 is installed without a System 30 Timer, set both S8 and S10 switches #5 to OFF so the message repeater input will be triggered only by vehicle detector signals.

S8 AND S10 DIP SWITCH FUNCTIONS

Refer to Figure 30 on page 23 for DIP switch locations.
