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
X
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
X
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 use this headset near a microwave oven. You may
X
experience decreased performance while the microwave oven
is operating.
If your headset is located near a modem, move your headset
X
and modem further apart from each other.
Relocate your telephone base to a higher location. You may
X
experience better reception by elevating the telephone base.
If other phones in your home or office are having the same
X
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
X
hear the ring tone when you are wearing the earpiece.
If you have pressed MUTE on the headset when it is ringing, it
X
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
X
line to allow all of them to ring simultaneously. Try unplugging
some of the other phones.
The layout of your home or office might be limiting the
X
operating range. Try moving the telephone base to another
location, preferably to a higher location.
