In Case of Fault
If you believe your scanner is defective, you should contact your dealer for
assistance. However, before you do so, check that the fault was caused by a
human error. Carefully reread the relevant section in the Owners Manual.
Initializing 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

NOTE: This procedure preserves the information you stored in the scanner's
working memory, while resetting all global radio parameters to factory de-
