This function enables a room to be monitored acoustically from another location. The handset should be at least 1 or 2 metres from the expected source of the sound. The handset dials a phone number you saved as soon as the volume in this room reaches a specific level. The called party can hear the sound in the monitored room when the call is answered. 

Note:    Please ensure that the number saved is not an external barred phone number and that an answering machine is not activated for the call number saved. The number saved here is used as a direct call number if the room monitor function is deactivated. The direct call number can be selected by activating the direct call key ().

Attention:    Direct call is not possible if the room monitor function is activated. The phone number must be changed when switching this function from room monitor to direct call if the call is to be transferred to different destinations.

A call received at a handset at which the room monitor function is activated is only signalled on the display. The ringer does not sound and the display and the keypad do not light up.
