Make sure the battery is installed and charged
correctly. For optimum daily performance,
return the cordless 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 unit's electrical power. Wait for
approximately 15 seconds, then plug it back
in. Allow up to one minute for the cordless
handset and telepone base to synchronize.
Remove and re-insert the battery of the
handset. If that still does not work, it may be
necessary to purchase a new battery.
Disconnect the telephone base from the
modular 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.

Place the handset in the telephone base or
charger for recharging.
Remove and re-install the battery and use it
normally until fully discharged, then recharge
the handset on the telephone base or charger
for 16 hours.
If the above measures do not correct the
problem, the battery may need to be replaced.
