If you cannot register a handset to a base unit on your Panasonic Cordless Telephone, it could be because the maximum number of base units (4) is already registered to the handset. Cancel unused base unit registrations from the handset. Also, ensure that you entered the correct PIN.
If your Panasonic Cordless Telephone handset beeps and/or flashes, it means the battery charge is low. You should fully charge the batteries.

If you cannot hear a dial tone on your Panasonic Cordless Telephone, ensure that you are using the supplied telephone line cord. Your old telephone line cord may have a different wiring configuration. Also, check that the base unit’s AC adapter or telephone line cord is connected. Disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates properly, contact our service personnel to have the unit repaired. If the working telephone does not operate properly, contact your phone service provider.

If the handset display is blank or dark on your Panasonic Cordless Telephone, it could be due to several reasons. The handset may be in screen saver mode. Activate the handset display again by pressing MCN when on a call, or pressing any dial key at all other times. Also, check if “LCD in charging” is set to “Off” while on charge, and change the setting if needed. Ensure the handset is turned on.

If your Panasonic Cordless Telephone handset does not ring, check if the ringer volume is turned off and adjust it. Also, make sure the do not disturb mode is turned off. If the handset is registered to multiple base units, it may not be able to make or receive calls if Eco mode is set to “Eco Plus” and Base unit selection is set to “Auto”. In this case, place the handset near the base unit, and change the setting to “Eco” or “Off”. Repeat for each base unit.
