• Insert the BP 4000 such that the wider charging contacts on the BP 4000 point at the LEDs on the
charger.
Due to the specific shapes of the charging slot and the BP 4000, you can only insert the BP 4000 in
the correct orientation.
1. Check that a BP 4000 is inserted in the transmitter. If the batteries inside the transmitter are dry or
standard rechargeable types, do not try to charge them.
2. Insert the transmitter into the charging slot so that the display on the transmitter points at the LEDs
on the charger.
The charger will automatically power up the transmitter in SILENT mode via the charging contacts.
The display will indicate "----". The transmitter will remain in SILENT mode and power down auto-
matically as you remove the transmitter from the charger.
The charging cycle will start automatically as soon as you insert a transmitter with a BP 4000 inside or a
BP 4000 into the charger.
