A user manual for your Panasonic phone is available on Panasonic's official website, Panasonic.com. To find a manual for your specific phone, go to panasonic.com, click Support on the top of the page, mouse over Downloads, and then click User manuals/installation manuals. From there, follow the instructions provided.
In order to read the manual, you may need to download Adobe Acrobat Reader. A link to download Adobe Acrobat Reader is available on the same page you used to download the manual for your phone. Alternatively, you can download the program at get.adobe.com. If you are still having trouble operating your Panasonic phone after reading the user's manual, call Panasonic's Customer Care Center.
