Battery installation & charging
The battery may have enough charge for short calls. For optimal
performance, we recommend that you charge the handset for
16 hours. You can keep the battery charged by returning the
handset to the telephone base after each use. When the battery
power is fully depleted, a full recharge takes about 16 hours.
When fully charged, the handset battery provides approximately
eight hours of talk time and four days of standby time.

minutes before registering to the main
telephone base.
To register a handset to your telephone

When you are replacing rather than adding a handset, for
your handsets to be numbered sequentially, you need to
delete all the handset registrations on the telephone base.
To de-register all handsets

for about 10 seconds (until the IN USE light turns on
and starts to flash), then release the FIND HANDSET
button.

light is still flashing. The IN USE light will flash for
approximately seven seconds.
3. Soon the handsets will show CONNECTING... and it will
take about 10 seconds to complete the de-registration
process. All handsets will show NOT REGISTERED if
deregistration is successful.
After deleting all handset registrations, you will need to
individually register each handset with the telephone base
(see page 4 for registration instructions).
NOTES:
1. If the de-registration process is not successful, you may need to reset
the system and try again. To reset: pick up the handset and press
the /FLASH button, then press the OFF/CLEAR button and place
the handset back into the telephone base. You may also reset by

below.
My phone
doesn’t work
at all
• Make sure the power cord is securely
plugged in.
• Make sure that the battery connector is
securely plugged into the cordless handset.
• Make sure the telephone line cord is securely
and firmly plugged into the telephone base
and the telephone wall jack.
• Charge the battery in the cordless handset
for at least 16 hours. For optimum daily
performance, return the cordless handset to
its base when not in use.
• Reset the telephone base. Unplug the unit’s
electrical power. Wait for approximately 15
seconds, then plug it back in. Allow up to
one minute for the cordless handset and
telephone base to reset.

I cannot get a
dial tone
• First try all the suggestions above.

of range.

Appendix

Troubleshooting
• If the previous suggestions don’t work,
disconnect the telephone base from the
telephone jack and connect to a different
phone. If there is no dial tone on that phone
either, the problem is in your wiring or
local service. Contact your local telephone
company.
• Your line cord might be malfunctioning. Try
installing a new line cord.
• First try all the suggestions above.
• Make sure you have a dial tone before
dialing. The cordless handset may take a
second or two to find the telephone base
and produce a dial tone. This is normal. Wait
an extra second before dialing.
• Eliminate any background noise. Noise from
a television, radio or other appliances may
cause the phone to not dial out properly. If
you cannot eliminate the background noise,
first try muting the cordless handset before
dialing, or dialing from another room in your
home with less background noise.
• If the other phones in your home are having
the same problem, the problem is in your
wiring or local service. Contact your local
telephone company (charges may apply).

oven or on the same electrical outlet. You
may experience decreased performance
while the microwave oven is operating.
• If your phone is plugged in with a modem
or a surge protector, plug the phone (or
modem/surge protector) into a different
location. If this solves the problem, re-locate
your phone or modem farther apart from one
another, or use a different surge protector.

be limiting the operating range. Try moving
the telephone base to another location,
preferably on an upper floor.
• If the other phones in your home are having
