Frequently Asked Questions
Do I need to lift the handset to make calls?
Some telephones allow on-hook dialing; refer to your telephone user guide for
instructions. For phones that do not allow on-hook dialing, you will need to lift
your handset for calls.
Why can’t I hear a dial tone through my headset?
You may have selected a telephone switch type that does not correspond to you
telephone. Try selecting another Telephone Compatibility setting (numbers 1-6
on the side of the amplifier).
Make sure you have inserted both the Telephone Cord and the Handset Cord
into the appropriate ports.
Why did my amplified headset system stop working?
Your batteries may be low; replace the 2 AA batteries. You can also purchase
an optional 9VDC @ 50ma AC Adapter, available at most electronics stores or
through GN Netcom (Part No. 760-0050).
