What to do if my Panasonic Telephone does not work?
If your Panasonic Telephone is not working, ensure the batteries are correctly installed. Fully charge the batteries. Check all connections. Unplug the base unit’s AC adaptor to reset the unit and turn off the handset; then reconnect the adaptor, turn on the handset, and try again. Also, the handset may not be registered to the base unit, so you may need to register the handset.
Why can't I hear a dial tone on my Panasonic Telephone?
If you cannot hear a dial tone on your Panasonic Telephone, ensure that you are using the supplied telephone line cord, as your old cord may have a different wiring configuration. Check that the base unit’s AC adaptor or telephone line cord is connected properly. To further diagnose the issue, disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates properly, the unit may need repair. If the working telephone does not operate properly, contact your service provider/telephone company.
Why is my Panasonic Telephone base unit beeping?
If the base unit of your Panasonic Telephone is beeping, it indicates that new messages have been recorded. Listen to the new messages.
Why I cannot make a call from my Panasonic Telephone?
If you cannot make a call on your Panasonic Telephone, you may have dialled a call restricted number. Also, verify that the key lock feature is turned off.
Why is my Panasonic Telephone not recording new messages?
If your Panasonic Telephone is not recording new messages, ensure that the answering system is turned on. If the message memory is full, erase unwanted messages. Check if the recording time is set to 'Greeting Only' and change the setting if needed. If you subscribe to a voice mail service, messages are recorded by your service provider/telephone company, not your telephone. Change the unit’s number of rings setting or contact your service provider/telephone company.
What does it mean when the Panasonic Telephone displays?
If your Panasonic Telephone displays , it means the handset is too far from the base unit, so move closer. Check that the base unit’s AC adaptor is properly connected and reconnect it if necessary. The handset may not be registered to the base unit, so register it. Activating one touch eco mode reduces the range of the base unit in standby mode; turn eco mode off if required.
Why is my Panasonic Telephone handset beeping and flashing?
If your Panasonic Telephone handset is beeping and/or flashing, it likely indicates that the battery charge is low. Fully charge the batteries.
Why has the time shifted on my Panasonic Telephone?
If the time on your Panasonic Telephone has shifted, it is likely due to incorrect time information from incoming Caller ID changing the time. Set the time adjustment to 'Manual' (off).
Why is caller information slow to display on my Panasonic Telephone?
Caller information may be slow to display on your Panasonic Telephone because, depending on your service provider/telephone company, the unit may display the caller’s information at the 2nd ring or later. Set the first ring to 'Off'. Also, try moving closer to the base unit.
