My telephone
does not work
at all. • Make sure the battery is installed and charged correctly
(page 7). For optimum daily performance, return the cord-
less handset to the telephone base after use.
• Make sure the power adapter is securely plugged into an
outlet not controlled by a wall switch.
• Make sure the telephone line cord is plugged firmly into the
telephone base and the modular wall jack.
• Unplug the telephone’s electrical power. Wait for approxi-
mately 15 seconds, then plug it back in. Allow up to one
minute for the cordless handset and base to synchronize.
• Charge the battery in the cordless handset for at least 16
hours.
• Remove and re-insert the battery. If that still does not work,
it may be necessary to purchase a new battery. Please refer
to the
Battery installation & charging section of this user's
manual (page 7).
• Disconnect the telephone base from the telephone line wall
jack and plug in a working telephone. If this telephone does
not work, the problem is probably in the wiring or the local
service. Call the local telephone company.
There is no dial
tone. • First, try all the above suggestions.
• Move the cordless handset closer to the telephone base. It
might be out of range.
• The telephone line cord might be malfunctioning. Try install-
ing a new telephone line cord.
• Disconnect the telephone base from the telephone jack and
connect a different telephone. If there is no dial tone on the
telephone either, the problem is in your wiring or local serv-
ice. Contact your local telephone company.
