Troubleshooting
I get noise, static, or a weak signal even when I'm near the
telephone base.
• You may be able to improve the performance of your cordless
headset by installing the headset base or 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 headset base or telephone base as far away as
possible from these types of electronic devices.
• Do not use this headset near a microwave oven. 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 headset base or telephone base to a higher
location. You may experience better reception by elevating the
headset base or telephone base.
• If other phones in your home or office are having the same
problem, the problem is in your wiring or telephone service.
Contact your telephone service provider (charges may apply).
I cannot hear a ring tone from the headset when there is an
incoming call.
• The headset does not have an external ringer. You can only
hear the ring tone when you are wearing the earpiece.
If you have pressed MUTE/ /
ringing, it mutes the ring tone of the headset. The ring tone
resumes on the next call.
• You may have too many extension phones on your telephone
line to allow all of them to ring simultaneously. Try unplugging
some of the other phones.
