• 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).
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/
FLASH
on the headset when it is
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.
• The layout of your home or office might be limiting the
operating range. Try moving the telephone base to another
location, preferably to a higher location.
• 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.
• Install the battery again, and then place the cordless headset
in the headset charger. Wait for the cordless headset to
reestablish its connection with the telephone base. Allow up to
one minute for this to take place.
• Your telephone line cord may be defective. Install a new
telephone line cord.
• 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).
