Lost instruction book

Did you lose the ability to read the model number on the bottom of the base or phone?

Typical Panasonic remote retrieval of messages involve the use of a code, as simple as 11. So you call in, press *11 and follow the guide to play back messages.

Of course, the key is to getting a manual. If you're looking for a USA manual, try this link: http://service.us.panasonic.com/operman/default.aspx
