Reset Global Parameters to Factory Defaults
If your scanner does not appear to be functioning properly, you can
reset the global radio parameters to their factory state without losing
any of your programmed data. Any custom changes you have made
to the radio’s global parameters will be lost.
Note: This procedure preserves the information you stored in
the scanner’s working memory, while resetting all global radio
parameters to factory defaults. V-Scanner memory is not affected by
this operation.
