USING THE MONITOR FUNCTION
The MONITOR function allows you listen to sounds from selected station
locations. It is most frequently used to monitor an invalid's or a child's room.
When a station is set to MONITOR, most sounds in that room will be transmitted
to all stations in the RADIO/INTERCOM mode.
1. Determine the station that is to be placed into the MONITOR mode.
2. Set that station's status switch to MONITOR.
3. Turn the station's VOLUME control to maximum.
4. Set listening stations to RADIO INTERCOM.
5. Reset the STATION STATUS switch when monitoring is no longer necessary.
NOTE: If program audio source is present during monitor, the program audio and
the sounds heard in monitor are heard at the same time on all stations in Radio
Intercom mode.
INTERCOM VOLUME CONTROL
The INTERCOM VOLUME control at the Master Station controls the intercom
volume throughout the system.

Optional Accessories

is connected to your IM-3303 Radio Intercom Master Station, the chime

DOOR RELEASE: If an optional NuTone door release push button has been
installed at the IM-3303 Master Station, use the button to open the door.
