Inserting a Transmitter into

the Charger

Fig. 1: Inserting transmitters

into the CU 700 charger.

• Rechargeable batteries (those included or those you may buy later) are delivered un-

charged or partially charged. Therefore, you will need to charge each new battery before

using it.

• The battery capacity indication will work best if you charge the batteries fully using the

CU 700 charger.

• If you replace the rechargeable batteries inside a transmitter be sure to fully charge the

batteries in order to calibrate the charging control system.

• Battery life depends on battery quality. Do not use any rechargeable batteries other than

the same type as those included with the charger.

Each charging slot features a tricolor STATUS LED that indicates the current operating status of the re-

spective charging slot (">…<" marks an LED flashing in the respective color):

1. Check that rechargeable batteries are inside the

transmitter battery compartment.

If there is no battery inside the battery compart-

ment, do not place the transmitter in a charging

slot before you inserted rechargeable batteries

into the transmitter.

2. Insert the transmitter into the charging slot so

that the display on the transmitter faces the LEDs

on the charger. The charger will automatically

power the transmitter via the charging contacts.

3. Never switch the transmitter ON during the

charging cycle. This may cause the charger to

falsely indicate a completed charging cycle be-

fore charging is actually completed.

• To avoid damaging the charger, do not try to charge dry batteries.
