My telephone base doesn’t work at all.
Make sure the power cord is securely plugged in.
Make sure you plug the telephone line cord securely and firmly into the
telephone base and the telephone wall jack.
Reset the telephone base. Unplug the electrical power. Wait approximately
15 seconds, then plug it back in. Allow up to one minute for the 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.
You may need to purchase four AA alkaline batteries as backup battery to
make the telephone base work in the event of a power failure. Please refer
to
Optional backup battery installation on page 9 in this user’s manual.
I cannot get a dial tone from the corded handset.
First try all the suggestions above.
Make sure you plug the handset cord securely and firmly into the
HANDSET jack on the telephone base and the corded handset.
If the previous suggestions do not work, disconnect the telephone base
from the telephone jack and connect to a different telephone. If there is
no dial tone on that telephone either, the problem is in your wiring or local
service. Contact your telephone service provider.
Your line cord might be malfunctioning. Try installing a new line cord.
I cannot dial out.
First try all the suggestions above.
Make sure you have a dial tone before dialing. The corded handset might
take a second or two to connect 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 might cause the telephone to not dial out properly. If you
cannot eliminate the background noise, first try muting the corded handset
before dialing, or dialing from another room by a cordless handset with less
background noise.
If the other telephones in your building are having the same problem,
contact your telephone service provider.
