Failure Modes

Flashing Blue and One Razzberry Tone
This indicates that the scanner has experienced a laser subsystem failure.
The scanner will try up to 3 times to correct the failure condition. If the
laser subsystem continues to fail, that subsystem (horizontal or vertical)
will be shut down and an error indication will be shown on the Diagnostic
Indicator Display. This error stays on the display until corrected. If the
remaining subsystem is still operational, scanning will continue using the
operational components!
Flashing Blue and White and Two Razzberry Tones

laser subsystem continues to fail, that subsystem (horizontal or vertical)
will be shut down and an error indication will be shown on the Diagnostic
Indicator Display. This error stays on the display until corrected. If the
remaining subsystem is still operational, scanning will continue using the
still operational components!
Continuous Razzberry Tone with both LEDs off
If, upon power up, the scanner emits a continuous razzberry tone, then the
scanner has an electronic failure. Return the unit for repair at an
authorized service center.
Three Beeps - on power up
If the scanner beeps 3 times on power up then, the nonvolatile memory
that holds the scanner configuration has failed. Return the unit for repair
at an authorized service center.
