To enjoy the many features of the system you must read these instructions. Keep this in a handy place for reference and help to perform the less frequently used functions.
SOME HELPFUL SUGGESTIONS
1. This radio and intercom is a SYSTEM of five or more speakers plus a door entry speaker that activates the Westminster Chime. The best performance and quality of audio requires you to understand there are two (2) separate volume controls that regulate the loudness of any room speaker.
a.The main loudness control is on the Master Unit marked RADIO VOLUME. This control regulates the MAXIMUM loudness of volume that will be received at all the room speakers. This volume control should always be adjusted when you select radio program, and be turned slightly LOUDER THAN YOUR COMFORT LEVEL with the Speaker volume control in the Master Unit fully "ON".
b.A secondary loudness control is on every Room Speaker including the Master Unit. This volume control should be used to a MINIMUM (Near Full On) to reduce the loudness setting of the main RADIO VOLUME control to the individual comfort level of any Speaker. Remember, the setting at the Master Unit is slightly louder than normal, and we adjust the individual Master Room speaker a little from full "ON" to the lower comfort level. What we don't do is turn the RADIO VOLUME control on the Master Unit to a very loud unnecessary high setting that can cause the amplifier to go into distortion, and then try to eliminate the poor audio quality (due to distortion) received at the room speaker with a major adjustment to turn the volume lower.
SPEAKER ON OFF VOLUME CONTROLS The ideal position for all SPEAKER controls (Master Room Patio) is the fully clockwise position. The speakers are fully "ON" at this setting. A setting lower than the 3 o'clock position will result in low level intercom communication even if the INTERCOM volume control at the Master Unit is fully ON. To turn a speaker "OFF" turn the volume control fully counterclockwise. At the OFF setting the Room Speaker cannot be MONITORED and will not be included in the ROOM LISTEN FUNCTION. This guarantees "PRIVACY" at each Room Speaker.
INTERCOM VOLUME CONTROL This volume control should be adjusted with the Room Speaker at high settings as described above. Communication and monitoring are most effective when the Room Speaker volume control is fully "ON".
TONE CONTROL This control adjusts the BASS/TREBLE tone of any selected program. Turn the control counterclockwise for more BASS, and clockwise for more TREBLE.
RADIO VOLUME CONTROL This is the MAIN VOLUME CONTROL for audio program. It should be adjusted to a slightly higher than comfort level with the Room Speaker at as near fully "ON" to your personal comfort.
CHIME VOLUME The Door Chime volume is adjusted at the factory assuming a near fully "ON" loudness of the Room Speaker volume control. If a different chime volume is desired, there is labeled internal volume control on the back of the Master Unit. Remove the Master Unit from the wall for adjustment with a small screw driver.

ROOM SELECTOR SWITCHES 1-12 PLUS MASTER UNIT Each switch controls a Room Speaker. Each Switch has three (3) positions, INT-ONLY, MON, and RAD-INT.
1.When the INT-ONLY (Intercom Only) position is selected and the numbered room speaker is "ON" the speaker will receive all intercom communications and the door chimes. The speaker WILL NOT receive a MONITORED ROOM, or RADIO PROGRAM.
2.When the MON (Monitor) position is selected the numbered room speaker is "ON" and the room speaker will transmit to all speakers that are in the RAD-INT position and are also "ON". The room speaker WILL NOT receive communications or chimes unless the MONITOR OVERRIDE switch (described below) is in the "ON" position. The sensitivity of a MONITOR Room Speaker varies with the number of speakers in the MONITOR position that are microphones active at the same time. The system works best with two (2) room speakers in the MONITOR mode at the same time, and the speaker volume control fully "ON".
3.When the RAD-INT (Radio-Intercom) position and the numbered room speaker is "ON" the room speaker will receive everything. The room speaker MUST BE in the RADINT position to receive a Monitored Room. The RAD-INT position is the position most often used to program the Room Speakers.
