Connecting external music on hold (MoH) ¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢
To feed in external music on hold, connect
the headphone output of an audio device
(CD player, cassette recorder or stereo sys-
tem) with a 3.5 mm jack plug to the jack
socket X (external MoH) on the underside of
the telephone system (Figure 1).
Set the volume of external music on hold on
the audio device. To set or check the
volume, call an internal user of the tel-
ephone system from an external source. The
external connection is put on hold when the
internal user presses the inquiry key "R" or
the "brokering key". You hear the music on
hold and can adjust the volume.
Note: tunes played must be free from third-
party proprietary rights (GEMA-free).
