DOOR STATION VOLUME ADJUSTMENTS
There are 2 adjustments on the door station which may require fine tuning after installation.
Note: A flat bladed screw driver with a blade width of 2 2.4mm is required to perform these adjustments.
The use of an incorrect screw driver will result in the pot being damaged.
Chime volume is adjusted by means of a miniature trim pot (VR2) situated on the door station
circuit board. Turning this pot will vary the chime volume throughout the system. This pot should
be adjusted so the chime volume comes through at an acceptable level at the internal room stations
at their default volume setting.
Speaker volume at the door station is adjusted by means of a miniature trim pot (VR1) situated on
the door station circuit board. Turning this pot will vary the speaker volume. This adjustment is
best made while someone is communicating to the door station from one of the internal stations.
CHANGING THE CHIME
The chime melody can be changed to any one of ten options by means of the two programming
switches (SEL & PROG) situated on the door station circuit board.
Press the Program button (PROG) – The red LED illuminates and the current chime plays.
Press the Select button (SEL) – The next chime option plays.
Repeatedly press the Select button until the desired melody is heard.
Press the Program button to lock in selection – The red LED flashes.
Press the Program button again to exit program mode – The red LED extinguishes.
Note: Pressing the Select button after all ten chime options have been sampled, will return to the first chime option.
