hi dear ,
check out the moving button on the back side of the scanner or that should be in any side too change that button to unlock side.

Shut down system and let it rest for a while. When restarted, it worked. ???

Hello,
I think you have to call the service. They will change the hole Scanner. Because you can't unlock the scanner by any buttons or mechanical trick!

Unlock the scanner for what? 800 MHz cellular frequencies? This scanner will not "unlock" for those frequencies.

lift up the scanner assembly to expose the underside of the scanner. slide the locking clip up from the locked position to the unlocked position. ( red )

To unlock a scanner open it where you would put cartridges in and look for a red or green colored tab hanging down. There should be a little picture of a padlock. You can switch it from lock to unlock. It's kept locked to protect the scanner during shipping.

Hope this is helpful...
