Diagnostic Indicator Display
There is a two-digit error code display located on the center printed circuit board (see illustration below). The
following is a list of possible error codes and their meanings. Some errors will require immediate scanner
maintenance.

Code
Description
01 Reserved
Figure 5. Diagnostic Indicator Display
02
RAM ERROR – The scanner’s Random Access Memory
(RAM) is tested as faulty. Return the unit for repair at an
authorized service center.
03
PROGRAM ERROR – The scanner’s software program is
failing. Return the unit for repair.
05
CONFIGURATION ERROR – The non-volatile
configuration memory did not agree with the data last
saved. Default configuration data is then used and the
scanner continues operating. This error is also
accompanied by 3 beeps. This error will remain during
operation as a reminder that this power cycle is scanning
against a default-generated configuration.
06
COMMUNICATION ERROR - The RS232 data line is being
held active. This causes the scanner to read a “break”
signal constantly and continuous attempts are made to
enter MetroSet configuration mode. A short on the RX
Data line can cause this condition. It can also be the result
of a laptop in power save mode. The scanner will abort
attempts to enter configuration mode after a short timeout.
The scanner can automatically recover from this condition
once the short in the RX Data line is corrected.
21
LASER #1 (left) ERROR – The laser in the left scanning
subsystem denotes a failure. The scanner will try three
times to correct the laser operation. If the laser error
persists, the left scanning subsystem will be shut down and
error code 21 will remain on the diagnostic indicator
display. If the right scanning subsystem is still healthy, it
will remain active and scanning until the unit can be
scheduled for repair at an authorized service center.
22
LASER #2 (right) ERROR – The laser in the right scanning subsystem denotes a failure. The
scanner will try three times to correct the laser operation. If the laser error persists, the right
scanning subsystem will be shut down and error code 22 will remain on the diagnostic indicator
display. If the left scanning subsystem is still healthy, it will remain active and scanning until the unit
can be scheduled for repair at an authorized service center.
