Hello,
The official code is a TRU9488, but after a power failure a few days ago, the machine has been blinking between "E4" and the UNIDEN continuosly.

The owner's manual says nothing about any E4 problems and it is still the weekend, so tech support (?) isn't open.

Has anyone and any experience and success with this problem? I am suspecting a battery issue.

Thank you!!!
