This means you give the complete authority to another user. After that, you cannot use the scanner or do anything with it before calling it back in the "Authorized Device".
The authorized user can use the scanner and even share it with others. But you can call it back any time and set the valid time for the user.
Please contact dealers or Panda support for the Licenses Code and search the receiver by email or user name. The expiration is used to set the valid time.
