Hi there and welcome
Do you mean you wish to register the Kindle with your own account instead of the one it is currently registered to?
ok, first you need to de-register it which removes all content until you register it again
to do this
If you are not already on the Home screen, press the Home button. 2. Press the Menu button. Make sure that Whispernet is turned on. 3. Move the 5-way down until "Settings" is underlined and press to select. 4. Press the 5-way to select "register" or "deregister" from the Settings screen. 5. If you're registering Kindle, enter your Amazon.com user name and password (the e-mail address and password ***** with your Amazon account) using the keyboard. 6. Navigate the 5-way to select "OK" to finish the process or "Cancel" to abort.
Then repeat the process and choose register and register with your own account
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
