No sound transmitted from the lift car to the call receiver
Press “0” to get an outside line. Make a call. 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 microphone.
Poor/distorted sound quality
Volume might be set too loud! Lower the volume and check again.
Interfering noise when the call is connected
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.

install the antenna near the unit or close to the cabelling.
