Using a handset as a
room monitor
If the room monitor is activated, a previ-
ously stored destination number is called
as soon as a set noise level is reached in
the room.
You can store an internal or external
number in your handset as the destination
number.
The room monitor call to an external
number stops after around 90 seconds.
The room monitor call to an internal
number (handset) stops after around
3 minutes (depending on the base
station). During use as a room monitor,
all keys are barred except for the end call
key a. The speaker of the handset is
muted. The end call key can only be used
to deactivate the handset.
When the room monitor is activated,
incoming calls to the handset are indi-
cated without a ringer tone and are only
shown on the screen. The display and
keypad are not illuminated and advisory
tones are also turned off.
If you accept an incoming call, the room
monitor mode is suspended for the dura-
tion of the call, but the function remains
activated.
If you switch off the handset, the room
monitor mode is deactivated. You must
reactivate the function when you switch
the handset back on.
