Scanner has all channels locked out

[WalterGraben]

Have Radio Shack Triple Trunking Handheld Radio Scanner purchased last Dec. When I push Scan it shows all channels locked out. When I run the channels and mark all unlock and to scan it still says all channels locked out. I have read manuel and tried steps shown to no avail. Need Help.

You may have the BANKS locked out (i.e. yes all the TG's are unlocked, but the banks are locked).
