No sound transmitted from the lift car to the call receiver.
Connect a normal phone (e.g. Comphone) to the plug on the main
unit and make a call to the car (press “1”). If the sound transmission
is OK in both directions, check if your emergency operator supports
the chosen alarm type. If no protocol is used, change the call type
to “VOICE”. If no sound is transmitted from the lift car, check the
polarity of the microphone wiring.
Poor/distorted sound quality.
Volume might be set too loud! Lower the volume and check again.
Interfering noise when the call is connected
If the main unit is installed on the car roof, the problem might be
due to induction in the phone cable. According to the phone
companies’ regulations, the phone line must be installed in a
separate cable.

Change the antenna position when a call is connected until you find
the optimal antenna position. Do not install the antenna near the
main unit or close to the cabelling.
