If you experience any of the problems in this section,
follow the instructions provided.
The PTC does not turn on
•
Charge or replace the PTC’s lithium-ion battery
pack.
•
Contact your Telxon service representative.
The laser scanner fails to read a label
See Appendix C for a list of
supported bar-code types.
•
Make sure the bar-code label you are trying to
scan is one of the bar-code types your PTC is
programmed to recognize.
See Appendix C for recommended
scanning distances.
•
Move the laser scanner closer to or farther away
from the bar-code label. You may not be scanning at
the correct distance.
•
Change the angle of the laser scanner to the
bar-code label. You may be too far above or below
the bar-code label or too far to the side to scan
properly.
See page 20 for instructions.
•
Clean the scanner lens.
•
The PTC’s application program may not support
scanned data at this particular field. Consult the
documentation for the PTC’s application program
to determine when the scanner and SCAN key are
enabled.
•
Point the scanner at a blank surface and press
the SCAN key. Look for the scanning line that
appears on the blank surface when the scanner is
operating. If no scanning line appears, follow your
organization’s procedure to have the scanner
serviced.
