Setting Program Audio
Controls
The volume levels required at each station may vary with the
location of the speaker and the size of the room where the
speaker is located. Spend some time experimenting with
volume levels, and adjust each speaker so that you can clearly
hear the radio and intercom. Use the following procedures to set
your system's volume levels.
1. At each remote station, turn the VOLUME control completely
clockwise to maximum volume.
2. At the master station, set the REMOTE SPEAKER STATUS
switches to the RADIO/IP position.
3. Turn the MASTER VOLUME control to maximum volume.
4. Turn the SYSTEM VOLUME control on the master station to
approximately 1/3 level.
5. Select an AM or FM radio station with a strong, clear signal.
6. Adjust the master station's SYSTEM VOLUME control until
you have enough volume at the remote station that requires
the highest volume (i.e. a large living room, family room,
basement, etc.).
NOTE: The master station and all remote stations (except
the door speakers) are equipped with their own volume
controls. Although the master station's SYSTEM VOLUME
sets the System's Volume Level, you may adjust an
individual speaker's volume level as desired.
7. Adjust the MASTER VOLUME control and all remote
stations' volume controls to the volume level you desire.
8. 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 or above.

Setting Intercom Volume

1. Initiate intercom call from the master station by pressing the
INSIDE/PATIO key.
2. Speak with a 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.
NOTE: The volume control at all stations should be set
between 2/3 and 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.
