Troubleshooting
My cordless handset isn't performing normally.
• Make sure the power cord is securely plugged into the
telephone base. Plug the power adapter into a different
working electrical outlet not controlled by a wall switch.
• Move the cordless handset closer to the telephone base. You
might have moved out of range.
• Reset the telephone base. Unplug the electrical power. Wait
for 15 seconds then plug it back in. Allow up to one minute
for the cordless handset and 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.
