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 transmis-
sion 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.

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
