Active room monitoring:
As soon as the ambient noise level near the monitoring phone exceeds the config-
ured level (noise sensitivity:
Very low , Low , Medium , High ) for more than 2 seconds, a
call is immediately triggered to an internal or external destination number you have
specified (destination phone). is displayed.
When the call is answered on the destination phone, a call is set up: one-way (connec-
tion only from the monitoring to the destination phone) or two-way (mutual call con-
nection during 1 minute in hands-free mode). Provided the call connection is not pre-
viously terminated neither on the monitoring nor on the destination phone, the con-
nection will automatically be terminated after 1 minute. The microphone for room
monitoring is reactivated after 1 minute and a call only triggered when the config-
ured level is again exceeded.
When the destination phone is busy, the microphone for room monitoring is reacti-
vated after 15 seconds. When the destination phone does not answer, the call is termi-
nated and the microphone for room monitoring is reactivated after 1 minute. A call is
only triggered again when the configured level is again exceeded.
When the monitoring phone receives an internal or external call from another phone
as the destination phone, this call is only visually but not acoustically signalled. You
can answer the call on the monitoring phone. You can also make a call on the moni-
toring phone. Once the call has been terminated, the monitoring phone immediately
switches back to monitoring mode. Please note that room monitoring is deactivated
as long as the monitoring phone is called or is in a call connection. Avoid these moni-
toring gaps by activating a call forwarding on the monitoring phone. A verification
call of the destination phone is yet possible with call forwarding.
Room monitoring mode:
• Active room monitoring with one-way call connection.
• Active room monitoring with two-way call connection.
• Passive room monitoring (
Listen only ).
Notes:
• Room monitoring based on DECT technology cannot be 100% reliable.
• 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.
