Background Music (BGM)
You can play background music through the speaker on your telephone. Music stops when the handset is
off-hook and also when your telephone rings. This feature requires preprogramming. MOH source must be
changed to external music source, and requires installation. In this case, music on hold will also be changed
to this BGM. BGM and external MOH use same source.

Headset Connection
You can use a headset when you need both hands free. Disconnect the handset cable from the telephone,
and connect the headset. In headset mode, use the ON/OFF key to answer a call, and do not pick up the
handset. Use an electret-type headset; a carbon-type headset is not compatible with the system.
Note that headset mode is disabled as a default. Enabling the mode requires preprogramming to prevent
false operation.
