Maintenance
Your device provides reliable and efficient operation with a minimum of
care. Although specific maintenance is not required, the following periodic
checks ensure dependable operation:
Inspecting Cords and Connectors
Inspect the interface cable and connector for wear or other signs of dam-
age. A badly worn cable or damaged connector may interfere with engine
operation. Contact your distributor for information about cable replace-
ment.
Troubleshooting
The engine automatically performs self-tests whenever you turn it on. If
your engine is not functioning properly, review the following
Troubleshoot-ing Guide to try to isolate the problem.
Is the power on? Is the laser aimer on?
If the laser aimer isn't illuminated, check that:
• The cable is connected properly.
• The host system power is on (if external power isn't used).
Is the engine having trouble reading your symbols?
If the engine 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 engine or in the decoder to which the
engine connects.
Is the bar code displayed but not entered?
The bar code is displayed on the host device correctly, but you still have to
press a key to enter it (the Enter/Return key or the Tab key, for example).
• You need to program a suffix. Programming a suffix enables the
engine to output the bar code data plus the key you need (such as
"CR") to enter the data into your application. Refer to
