How to record the answering message?

Might not be erasing former messages and just recording new ones - Erase function may not be working. Try erasing all messages and see what happens.

Press and hold the ANNC/SKIP button. Record your message at the beep. Release ANNC/SKIP when done.


You may view the manual here.

Call your phone while you're away, and when your message starts to play enter your remote code. After that, you use the keypad on the phone to control message playback, record a new greeting, etc.

"DECT 6.0" is a generic term for the cordless phone technology, and not your phone model number. You'd find that on a label on the back or bottom of the base unit. Without a specific model I can't look for a manual and give details, but if you have the model listed you can download the manual from Panasonic here. It gives all the steps to set up your remote code and the commands to use. If you have a different model phone you can look for your manual at Panasonic's support page.

For the model listed above, the default remote code is 111. The list of remote commands is

Key Remote command
{1} Repeat message
(during playback)*1
{2} Skip message (during
playback)
{4} Play new messages
{5} Play all messages
{6} Play greeting message
{7} Record greeting

Maybe this list works for your phone too.

2. Erase own greeting just recorded >menu>answe...device>erase messa...>erase greet...>Ok
3. Then try Menu> answering device>play greeting....voila. Prerecorded message plays.
Hope This helps.

Generic message mean the origional memo from manufacture? or the record message from caller far end? Try to power off and on again, record your personal anoucement one more time.

I read thru the manual. There is nothing bout recovery of factory messages. If you recorded your own, try deleting it. Or unplug the base from power and try a reset. This is from the manual. At the end, I gave you a link to the manual!

sorry it sounds like the folder may be lost forever.once you pressed the record button, the recorder knew it as a new recording in that folder.look at it like a answering machine going out message. if you made a mistake,and you wanted to record a new message,the old message would be erased.if your folder was on a cassette recorder, you would have only erased those few seconds.
sorry
