What to do if my Panasonic KX-TG5621S Cordless Telephone does not work?

If your Panasonic Cordless Telephone is not working, please ensure the battery is correctly installed and fully charged. Also, check all connections. Unplugging the base unit’s AC adapter to reset the unit, then reconnecting it, might also resolve the issue. If the handset isn't registered to the base unit, register it.
