Troubleshooting
I cannot hear any ring tone from the cordless headset when there is an
incoming call.
The headset does not have an external ringer. The ring tone can only be heard
through the headset earpiece.
Make sure the headset ringer volume is not set to the lowest level (page 36).
If you have pressed MUTE/FLASH on the cordless headset when it is ringing, it
mutes the ring tone of the headset. The ring tone resumes on the next call.
The headset may be too far from the telephone base. Move it closer to the
telephone base.
You may have too many extension phones on the telephone line to allow all of them
to ring simultaneously. Unplug some of them.
The layout of your home or office may be limiting the operating range. Try moving
the telephone base to another location, preferably on a higher location.
If other telephones in your home are having the same problem, the problem is in
the wiring or telephone service. Contact your telephone service provider.
Other electronic products such as HAM radios and other DECT phones can cause
interference with your cordless phone. Try installing your phone as far away as
possible from these types of electronic devices.
Test a working telephone at the telephone wall jack. If another telephone has the
same problem, there may be problem with the telephone wall jack. Contact your
telephone service provider.
The telephone line cord may be defective. Install a new telephone line cord.
I cannot register a cordless headset.
Only two headsets can be registered to this telephone system (page 106).
If you have already registered the maximum numbers of handsets and/or headsets,
you need to follow the deregistration instructions before registering a headset.
Refer to Expand your telephone system on page 105 and Deregister handsets/
headsets on page 107.
Make sure that all registered handsets, headsets and the telephone base are in idle
mode when registering a headset.
Follow the steps in Common cure for electronic equipment (page 120), then try
again to register a headset.
