Room monitoring mode:
• Active room monitoring with one-way call connection.
• Active room monitoring with two-way call connection.
• Passive room monitoring
Notes:
• The reliability of the room monitoring depends on the quality of the radio connec-
tion.
• Extraneous noises in the monitored room call lead to false calls.
• Therefore no liability can be assumed for failed monitoring calls or for false calls.
Passive room monitoring:
You can also listen into the monitored room using a verification call. Call the monitor-
ing phone from the destination phone. When the destination number is an external
call number, CLIP may not be suppressed. The monitoring phone answers the call
automatically and without acoustic signalling and sets up a one-way or two-way call
connection depending on the settings. This is possible even if a call forwarding is acti-
vated on the monitoring phone.
There is no time limit to the duration of a verification call, which must be terminated
on the destination phone or on the monitoring handset. Once the call has been
cleared down, the monitoring phone immediately switches back to monitoring mode.
