resetting/initializing your scanner
If the scanner’s display locks up or does not work properly after you connect a power source, you
might need to reset or initialize it. If you have problems with the scanner, first try resetting it,
which will retain items stored in memory. If that does not work, initialize the scanner. You may be
able to save the information in your scanner’s memory to your computer, or another scanner before
initializing it. See “Cloning the Programmed Data”.
resetting your scanner
1. Trun off your scanner, and then turn it on again.
2. Insert a pointed object into the reset hole on the back of the scanner. Then, gently press and
release the reset button. Pressing reset does not clear the scanner’s working memory of the
V-Scanner folders.
initializing your scanner
Initializing your scanner clears all information stored in your scanner’s working memory. Initialize
your scanner only when you are sure it is not working properly.
1. Turn off the scanner, then turn it on again. Multi-system Trunking Scanner appears.
2. Press 0 while Multi-system Trunking Scanner appears.
