Suggestion
Clean the charging contacts on the cordless handset(s) and telephone
base each month using a pencil eraser or a dry non-abrasive fabric.
Make sure the power adapter and telephone line cords are plugged in
correctly and securely.
Unplug the power adapter. Wait for 15 seconds before plugging it back
in. Allow up to one minute for the cordless handset and telephone
base to synchronize.
The telephone might be malfunctioning. Please refer to the Limited
Warranty section of this user's manual for further instruction.
This is a signal that the battery is very low, completely depleted, or
when there is no electrical contact between the battery and the tele-
phone base.
Ensure the connector of the battery is securely plugged into the hand-
set and place the handset in the telephone base for charging.
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 installing 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 this telephone either, the
problem is in the wiring or the local service. Contact the local tele-
phone company.
