Installation manual

4 Check that the MIC and Voice are connected to JP15 on the Control
Panel. If voice is not heard, the problem is in the Audio path.
5 Check that the Keypad Volume Control knob on the Keypad and the
trimmer in the Door Station is not all the way down.
None of the Indicator LEDs on the Keypad are on
At least one LED should always be on steady or blinking.
1 Check that the 12V and Ground are connected to the corresponding
terminals on the Comfort panel, and the wires are not reversed.
2 Use a multimeter to check that 12V is actually coming to the Keypad
Playback of Recording is Distorted
Usually, this is because the Microphone trimmer is set to too high a
gain. Reduce the gain by tuning the MIC trimmer VR1 lower (clockwise)
on the Control panel.
Cannot Hear Two-way Audio for Voice Station or Door Station
If the remote phone is unable to hear the Keypad or Door Station
whenever there is a sound on the monitored area, there may be wrong
settings in some of the Tuning Parameter Locations. The following
apply to Rev C boards with version 4 firmware. The 1st two columns
show Tune Parameter values in the CS-Xpress Tuning Parameter
screens to check, while the 2nd two columns show the Locations and
values to check. Check either the CS-Xpress or Locations values.
