Table 13-1. Troubleshooting the PDT 8100 (continued)
Problem
Your PDT 8100 terminal
does not accept scan
input.
Note: If, after performing these checks, the terminal is still not reading
symbols, contact your distributor or Symbol Technologies.
Cause
Scanning application is
not loaded.
Unreadable bar code.
Distance between exit
window and bar code is
incorrect.
Terminal is not
programmed for the bar
code.
Terminal is not
programmed to generate
a beep.
Battery is low.
Maintenance and Troubleshooting
Solution
Verify that the terminal is loaded with a
scanning application. See your System
Administrator.
Be sure the symbol is not defaced.
Be sure you are within proper scanning range.
Be sure the terminal is programmed to accept
the type of bar code you are scanning.
If you are expecting a beep on a good decode
and don't hear one, check that the application is
set to generate a beep on good decode.
If the scanner stops emitting a laser beam when
you press the trigger (scan button), check your
battery level. When the battery is low, the
scanner shuts off before the terminal notifies
you of the low battery condition.
Note: If the scanner is still not reading symbols,
contact your distributor or Symbol
Technologies.
