Troubleshooting
My cordless handset isn't performing normally.
•
Make sure you plug the power cord securely into the telephone base. Plug the power
adapter into a different, working electrical outlet without a wall switch.
•
Move the cordless handset closer to the telephone base. You might have moved
out of range.
•
Unplug the electrical power. Wait for 15 seconds, and then plug it back. Allow up
to one minute for the cordless handset and telephone base to reset.
•
Other electronic products such as HAM radios and other DECT phones can cause
interference with your cordless phone. Try installing your phone as far away as
possible from these types of electronic devices.
The batteries do not hold a charge.
•
Charge the battery in the cordless handset for at least 10 hours. For optimum daily
performance, return the cordless handset to the telephone base or charger when
not in use.
•
If the battery is depleted, it might take approximately 30 minutes to charge the
handset before it shows Low battery. Refer to the table on page 4 for details.
•
You might need to purchase a new battery. Please refer to Battery installation
and charging in this user's manual on page 4.
I experience poor sound quality when using the speakerphone.
•
For increased sound quality while using the speakerphone, place the handset on a
flat surface with the dial pad facing up.
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 line) through
your telephone line, you must install a DSL filter between the telephone line cord
and the telephone wall jack (see page 3). 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 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 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 outlet.
You might experience decreased performance while the microwave oven is
operating.
•
If you plug your phone in with a modem or a surge protector, plug the 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 might have better reception in a
high area.
•
If other phones in your home are having the same problem, contact your telephone
service provider (charges may apply).
