station’s volume controls to the volume level you desire.
In order to have proper intercom audio levels, it is
recommended that the MASTER VOLUME and remote
stations’ VOLUME controls be set at
2 ⁄
3
volume or higher.
SETTING INTERCOM VOLUME
1. Initiate an intercom call from the master by pressing the
INSIDE/PATIO key.
2. Speak with a clear normal voice about 2-3 feet from the
master station’s speaker.
3. Adjust the INTERCOM VOLUME control until the initiating
station’s audio is clearly heard at all stations in the
system.
PLEASE NOTE: The volume control at all stations should be
set between
1 ⁄
2
to maximum volume for proper intercom
operation.
4. Repeat the above procedure at several remote station
locations until an acceptable intercom audio level is
achieved at all stations.
SETTING INTERNAL INTERCOM VOLUME
CONTROL
The internal intercom volume control has been factory set for
optimum intercom operation. Should the intercom gain need
to be adjusted beyond the range of the Intercom Volume
Control behind the left front door, use the following procedure:
1. Refer to Figure 27. Using a thin-blade screwdriver, adjust
the internal control counter-clockwise as viewed from the
rear of the master station panel. This adjustment will
reduce the intercom gain.
2. To increase the intercom gain, turn the internal control
clockwise.
