Chapter 4 — Troubleshooting and Maintaining the CN50
CN50 Mobile Computer User’s Manual 57
Resetting the CN50
You rarely need to reset the computer. If the computer does not
resume after pressing the £ button, or if the computer or an
application lock up, you may need to reset the CN50. The CN50 uses
the configuration currently saved in flash memory during the boot
process. There are two ways to reset the CN50:
• Warm booting the CN50
• Cold booting the CN50
Warm Booting the CN50
You may need to perform a warm boot to correct conditions where an
application stops responding to the system. You can send a warm
boot command by using a Microsoft API.
The com
puter systematically shuts down, restarts, and goes through
the initialization process.
The scanner does not
read the bar code
labels quickly, or the
scanning beam
seems to be faint or
obscured.
The scanner window may be dirty. Clean the window
with a solution of ammonia and water. Wipe dry. Do
not allow abrasive material to touch the window.
The scanned bar
code data that
appears in your
application does
not match the data
encoded in the bar
code label.
The CN50 may have decoded the bar code label in a
different bar code symbology. Try scanning the bar
code label again. Make sure you scan the entire label.
