Problem
Probable Cause
Solution
Information could not be
read from the tag.
The tag may be outside of
the scanning area.
Make sure the tag is no
more than 60 inches from
the scanner.
The tag may have passed
too quickly past the
scanner.
Make sure the tag is in
the scanning area for at
least 3 milliseconds.
No RF Power
The supplied SCS
Diagnostic tag may be
used to verify that the
scanner is transmitting RF
power. When held within
a few inches of the
transmit antenna, the LED
on the Diagnostic tag will
glow Red, indicating the
presence of the RF field.
Same as above, but
the Activity/Error LED
flickers constantly.
RF Interference is
disrupting scanner-to-tag
communications.
See “Chapter 3-RF
Communications” for
suggestions on improving
communications.
