Appendix B
Troubleshooting
I hear other
calls while using
my phone.
• Disconnect the telephone base from the
telephone jack, and plug in a different
telephone. If you still hear other calls, the
problem is probably in your wiring or local
service. Call your local telephone company.

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.
• Do not install this phone near a microwave
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 doesn't solve the problem,
re-locate your phone or modem farther
apart from one another, or use a different
surge protector.
• Relocate your phone to a higher location.
The phone will likely have better reception
when not installed in a low area.
• 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).
