SECTION 4 – ADJUSTMENTS

4.1 Speaker Volume

1. Open the front of the telephone entry system and locate the speaker volume adjustment.
2. Place a phone call from the telephone entry system to a resident. While they are talking,
adjust the speaker volume potentiometer for adequate sound. To increase the volume
rotate the potentiometer clockwise, to decrease the volume rotate the potentiometer
counter clockwise.

4.2 Feedback

1. Open the front of the telephone entry system and locate the feedback adjustment.
2. Place a phone call from the telephone entry system to a 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.

4.3 Click Sensitivity

1. Open the front of the telephone entry system and locate the click sensitivity adjustment.
2. Place a phone call from the telephone entry system to a resident with a rotary dial type
phone. After they answer, ask the resident to dial 9 while you adjust the click sensitivity
potentiometer (the resident may have to dial 9 several times for you to obtain the correct
adjustment). When the door or gate opens, this is the correct adjustment for the click
sensitivity.
3. NOTE: Adjusting the click sensitivity too high (potentiometer fully clockwise) could cause
the system to respond to loud noises while it is in use. If this happens, rotate the click
sensitivity potentiometer counter clockwise 1/8 turn and re-test the system. You may
have to perform this step several times to find the correct adjustment.

4.4 Display Contrast

1. Open the front of the telephone entry system and locate the contrast adjustment.
2. Turn the contrast potentiometer clockwise and then counter clockwise until the display is
satisfactory.

4.5 Master Code Switch

1. The master code switch is left in the off position for normal operation. Turn the master
code switch on when setting the system master code. See programming instructions to
set the system master code. If the master code switch is turned on and a new master
code is not entered, the system will sound a long tone after approximately 30 seconds.
This tone will continue every 30 seconds until a new master code is entered, or until the
switch is turned off.
