IN CASE OF DIFFICULTY
If you have no dial tone
Check all the previous suggestions. If you still do not hear a dial tone,
disconnect the phone and try another phone in the same jack. If there is
no dial tone on that phone either, the problem is probably in your wiring
or local service. Call your local telephone service company.
If you hear noise or interference when using the phone
You may be out of range. Move closer to the base.
Press h to change to another of the 25 channels available. If
the noise is exceptionally loud, move closer to the base before
changing channels.
Household appliances plugged into the same circuit as the base can
sometimes cause interference. Try moving the appliance or the base
to another outlet.
The layout of your home or office may be limiting the operating range.
Try moving the base to another location, preferably on an upper floor.
If the phone does not ring when you receive a call
Make sure the handset RINGER switch is set to ON.
Make sure the telephone line cord is connected firmly to the base and
the telephone jack. Make sure the power cord is plugged into an
outlet not controlled by a wall switch.
You might be too far from the base. Move closer to the base.
You might have too many extension phones on your telephone line to
allow all of them to ring. Try unplugging some of the other phones.
If you hear other calls while using the phone
Press h to change to another channel.
Disconnect the base from the telephone jack, and plug in a corded
telephone. If you still hear other calls, the problem is probably in
your wiring or local service. Call your local phone company.
If your telephone misdials or you don’t hear the other person
right away
It might take a few seconds for your handset to find a good connection
to the phone system. While it is searching, the PHONE light blinks
rapidly. Do not start dialing until the PHONE light is on steadily.
If you have dial pulse (rotary) service, you’ll need to reset the dial
mode. See Step 10 of “Table/Desk Installation” in the INSTALLATION
section of this manual.
If you have touch tone service and you hear clicks when you are
dialing, you’ll need to reset the dial mode. See Step 10 of “Table/Desk
Installation” in the INSTALLATION section of this manual.
