2. Open the battery compartment by sliding the lock of the compartment
cover into the direction of the compartment. The cover can be opened
and then removed.
3. Insert three AAA batteries into the battery compartment. Note the +
and – icons on the batteries and inside the battery compartment.
4. Place the battery compartment cover over the battery compartment
so that the locking nose of the cover is inserted into the corresponding
notch on the transmitter cradle. Then close the battery compartment
cover until it locks in place.
While the transmitter cradle is on battery power, it will not charge the
built-in headphone battery.
If you have inserted batteries into the transmitter cradle and you
connect the power adapter to the power socket (12), battery operation
will be disabled automatically. This helps you to save battery power
whenever the device is connected to the mains via the power adapter.
