Speaker Volume

The speaker volume potentiometer is labeled SPEAKER VOL on the control board. The speaker volume should be adjusted for

adequate sound. Adjusting the speaker volume too loud could cause feedback from the microphone.

1. Open the front of the telephone entry system and locate the speaker volume adjustment.

2. Push the "Push To Call" button to place a call to the resident. While they are talking, adjust the speaker volume potenti-

ometer for adequate sound. To increase the volume rotate the potentiometer clockwise, to decrease the volume rotate the

potentiometer counter clockwise.

Feedback 1

The feedback 1 potentiometer is labeled FB1 on the control board. This adjustment minimizes feedback from the microphone to

the speaker when the system is connected to the resident telephone.

1. Open the front of the telephone entry system and locate the Feedback 1 adjustment.

2. Push the "Push To Call" button to place a call to the resident. After they answer, ask the resident to remain silent.

3. While rubbing your finger across the microphone hole, rotate the feedback potentiometer clockwise, and then counter

clockwise. When the noise from the speaker is minimum, this is the correct adjustment for the feedback potentiometer.

Feedback 2

The feedback 2 potentiometer is labeled FB2 on the control board. This adjustment minimizes feedback from the microphone to

the speaker when the system has placed a call to an outside phone line. Note: Feedback 2 is not used when the 1812 is

programmed in the intercom mode.

1. Open the front of the telephone entry system and locate the Feedback 2 adjustment.

2. Enter one of the preprogrammed phone number directory codes (01, 02, 03) on the system keypad to place a call to

an outside number (see 2.5.3 to program an outside number). After the party answers, ask them to remain silent.

3. While rubbing your finger across the microphone hole, rotate the feedback potentiometer clockwise, and then counter

clockwise. When the noise from the speaker is minimum, this is the correct adjustment for the feedback potentiometer.
