Your telephone may not be fully immune to the radio transmission between your headset and base. To
overcome this problem, move the base at least 30 cm/12” away from the phone. If you have a European
version, you can instead choose to set the headset to Low Power mode.
The person on the other end of the line says he/she cannot hear me.
Ensure that the Telephone Termination Switch is in the correct position and that you have adjusted the
Transmit Power. Please refer to the relevant section in the reference guide.
When I press the MFB the GN1000 lifts but the call is not connected.
When using your GN9120/GN9125 with a GN1000, make sure that the base is connected to the telephone’s
handset port and not the headset port. Please refer to the illustrations in the GN1000 Quick Guide.

Please make sure that the GN9120/GN9125 is compatible with your telephone system, and set the
GN9120/GN9125 in the correct mode. For standard telephones and for use with GN1000, please make
sure to put the GN9120/GN9125 in RHL mode.

Your headset may need pairing to the base. Refer to page 7 “Registering a new master headset” in this
