GRE PSR 310 software update

[CALFIREFOBS]

Howdy folks
Can anyone out there advise me on updating the software for my GRE PSR 310? I'd like to keep the scanner, I'm hoping for a simple fix.
I'm not having problems with it, it's a great scanner.
Thanks!

First press 3 then turn on. What version is shown? 1.5 is the latest. Updates to 1.5 available here GRE America Inc. Word of caution read the instructions file in the zip folder step by step.

Thanks again.

The GRE website under psr 310/410 cpu version 1.08 but that's the path to firmware 1.5.
