Troubleshooting
The batteries do not hold a charge.
If the cordless handset is in the telephone base or charger and the charge
f
light is not on, refer to The charge light is off or blinking (page 152).
Charge the battery in the cordless handset for at least ten hours. For
f
optimum daily performance, return the cordless handset to the telephone
base or charger when not in use.
If the battery is depleted, it may take approximately 30 minutes to charge
f
the handset before it shows Low battery. Refer to the table on page 11
for details.
You may need to purchase a new battery. Please refer to
f
Battery installation and charging in this user's manual on pages 11-12.
I get noise, static, or weak signals even when I'm near the telephone base.
If you subscribe to high-speed Internet service (DSL - digital subscriber
f
line) through your telephone line, you must install a DSL filter between
the telephone line cord and the telephone wall jack (page 10). The filter
prevents noise and caller ID problems as a result of DSL interference.
Please contact your DSL service provider for more information about
DSL filters.
You may be able to improve the performance of your cordless phone
f
by installing your new telephone base as far as possible from any other
existing cordless telephone system that may already be installed.
Other electronic products such as HAM radios and other DECT phones, can
f
cause interference with your cordless phone. Try installing your phone as
far away as possible from these types of electronic devices.
Do not install this phone near a microwave oven or on the same electrical
f
outlet. You may experience decreased performance while the microwave
oven is operating.
If you plug your phone in with a modem or a surge protector, plug the
f
phone (or modem/surge protector) into a different location. If this does
not solve the problem, relocate your phone or modem farther apart from
one another, or use a different surge protector.
Move your phone to a higher location. The phone may have better
f
reception in a high area.
If other phones in your home are having the same problem, contact your
f
telephone service provider (charges may apply).
