Appendix F
Troubleshooting
SYMPTOM:
I get the “No Card Detected” icon in the task tray and
can’t trigger the laser or scan any bar codes.
POSSIBLE REASON
SOLUTION
Your mobile computer does not
recognize the ISC.
Make sure the ISC is inserted
properly. If necessary, remove and
reinsert. If using battery power, be
sure to tap
Yes
if asked if you want
to use battery power.
SYMPTOM:
When I try to scan, the laser fires, but no data appears on
my screen, and the laser eventually shuts off.
POSSIBLE REASON
SOLUTION
The laser beam is too close or too far
from the bar code.
Practice so you get accustomed the
most effective distance and scanning
angle.
The bar code is incorrectly formatted
or poorly printed.
Try scanning a bar code that is
correctly formatted or printed well,
such as on a retail package.
The bar code symbology may be
disabled in the ISC configuration.
Use Scan Demo to determine the
symbology. If needed, reconfigure
the ISC.
SYMPTOM:
When I press the trigger button, nothing happens.
POSSIBLE REASON
SOLUTION
You programmed the trigger button
incorrectly.
Test the button by assigning a
different program to it and make sure
it works properly.
