Troubleshooting
• Test a working phone at the phone jack. If another phone has
the same problem, there may be a problem with the phone
jack, wiring or service. Contact your telephone service provider
(charges may apply).
I hear other calls while using my headset.
• Plug a different telephone into the telephone jack that you
are currently using. If you still hear other calls, the problem
is probably in your building's wiring or local service. Call your
telephone service provider.
I want to use my headset with a different telephone base.
• You need to deregister the headset from the current telephone
base (page 10), and then register it to the new telephone base
(page 9).
My calls cut in and out while I'm using my cordless headset.
• Other electronic products such as HAM radios and other DECT
phones can cause interference with your cordless headset. Try
installing your telephone base as far away as possible from
these types of electronic devices.
• Do not install the headset near a microwave oven or on
the same electrical outlet. You may experience decreased
performance while the microwave oven is operating.
• If your headset is located near a modem, move your headset
and modem further apart from each other.
• Relocate your telephone base to a higher location. The headset
will have better reception when not installed in a low area.
• If other phones in your home or office are having the same
problem, the problem is in your wiring or local service. Contact
your telephone service provider (charges may apply).
