DKS Enterprises 1803PC, 1815, 1817 Adjustments, Speaker Volume, Feedback, Click Sensitivity

SECTION 4 – ADJUSTMENTS

4.1Speaker 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.

4.2Feedback

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.

4.3Click 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.

4.4Display Contrast (1815 Only)

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.

4.5Display Contrast (1817 Only)

1.There are two contrast potentiometers on the 1817 LCD control board labeled CONTRAST. The left one will adjust the contrast on the lower screen and the right one will adjust the contrast on the upper screen. These adjustments are normally set at the factory. Let the system run for 10 minutes before making any display contrast adjustments.
