Troubleshooting
• Move the cordless headset closer to the telephone base. You
might have moved out of range.
• Reset the headset. Power off the headset and then power it on.
• 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.
I get noise, static, or a weak signal even when I'm near the
telephone base.
• If you subscribe to high-speed Internet service (DSL - digital
subscriber line) through your telephone line, you must install a
DSL filter between the telephone line cord and the telephone
wall jack. The filter prevents noise and caller ID problems
caused by DSL interference. Contact your DSL service provider
for more information about DSL filters.
• You may be able to improve the performance of your cordless
headset by installing the telephone base at least one foot from
any cordless telephone system. If separating them by one foot
does not help, try moving the headset farther away.
• 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 this headset near a microwave oven or in
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. You may
experience better reception by elevating the telephone base.
