Visual
Alternating Flashing of Blue and White
This indicates the scanner is configuration mode. A
razzberry tone indicates that an invalid bar code has been
scanned while in this mode.
The scanner needs to have a Flash ROM upgrade if the
alternating flashing of the white and blue LEDs occurs during
startup and is accompanied by three beeps.
Steady White, Blue off
This indicates the scanner may be waiting for
communication from the host.
Failure Modes
One Razzberry Tone – On Power Up or During Scanning
This indicates the scanner has experienced motor or laser
failure
Three Beeps – On Power Up
If the scanner beeps 3 times on power up then the non-
volatile memory (NovRAM) that holds the scanner
configuration has failed. If the scanner does not respond
after reconfiguring, return the scanner for repair to an
authorized service center.
