Troubleshooting
The reader will automatically perform a set of self-tests whenever you
turn it on. If your reader doesn’t seem to be functioning properly, follow
these steps to try and isolate the problem.
1. Is the power on? Does the illumination beam come on?
If no illumination beam, check that...
• all connections are fully seated and in the appropriate port(s).
• the host system power is on (if external power isn’t used).
• the trigger works.
2. Is the reader having trouble reading your symbols?
If the reader isn’t reading symbols well, check that the symbols...
• aren’t smeared, rough, scratched, or exhibiting voids.
• aren’t coated with frost or water droplets on the surface.
• are enabled in the reader. See the Product Reference Guide
(PRG) for more about configuring the reader to read symbolo-
gies.
