PROGRAMMING AND ADJUSTMENTS FOR VF102 DOOR STATION DOOR STATION ADJUSTMENTS There are 3 adjustments on the Door Station that may require fine-tuning after installation. A flat bladed screwdriver with a blade width between 2mm and 2.4mm is required for these adjustments. Using the wrong screwdriver will damage the pot. Speaker Volume Speaker volume at the Door Station is adjusted by means of a miniature trim pot (VR1) located in the centre of the circuit board. Turning this pot will vary the speaker volume. This adjustment can be made while someone is communicating to the Door Station from one of the internal stations or while the chime is activated. Chime Volume Chime volume is adjusted by means of a miniature trim pot (VR2) situated at the bottom of the circuit board as indicated below. Turning this pot will vary the chime volume throughout the entire system. This pot should be adjusted so the chime volume comes through at an acceptable level at an internal Room Station with its slide volume control set to around level 4 or 5. Microphone Gain The microphone gain pot (VR3) is generally set half way and would rarely require adjustment. The microphone level can be turned down where the Door Station causes feedback in a Room Station due to close proximity or can be turned up if the communication level from the Door Station is too low - see "Adjustments for VR102 Room Stations" for more detail.
