SWITCH ERROR – The switch used for volume selection or sleep mode is detected in error (always closed). The
condition is self-correcting if possible. If the error persists, return the unit for repair at an authorized service center.
The scanning operation can continue with this error active.
21
LASER #1 (VERTICAL) ERROR – The laser in the vertical scanning subsystem denotes a failure. The scanner
will try three times to correct the laser operation. If the laser error persists, the vertical scanning subsystem will be
shut down and this error code will remain on the Diagnostic Indicators.
22
LASER #2 (RIGHT HORIZONTAL) ERROR – The right laser in the horizontal scanning subsystem denotes a
failure. The scanner will try three times to correct the laser operation. If the laser error persists, and the left
horizontal laser (#3) is also in error, the horizontal scanning subsystem will be shut down and this error code will
remain on the Diagnostic Indicators.
23
LASER #3 (LEFT HORIZONTAL) ERROR – The left laser in the horizontal scanning subsystem denotes a failure.
The scanner will try three times to correct the laser operation. If the laser error persists, and the right horizontal
laser (#2) is also in error, the horizontal scanning subsystem will be shut down and this error code will remain on
the Diagnostic Indicators.
24
LASER #1 (VERTICAL) HIGH CURRENT WARNING – The laser in the vertical scanning subsystem is drawing
excessive current. This could be a warning for a future total failure. Have the unit checked at an authorized
service center when convenient.
25
LASER #2 (RIGHT HORIZONTAL) HIGH CURRENT WARNING – The laser in the vertical scanning subsystem is
drawing excessive current. This could be a warning for a future total failure. Have the unit checked at an
authorized service center when convenient.
26
LASER #3 (LEFT HORIZONTAL) HIGH CURRENT WARNING – The laser in the vertical scanning subsystem is
drawing excessive current. This could be a warning for a future total failure. Have the unit checked at an
authorized service center when convenient.
27
LASER #1 (VERTICAL) UNDERCURRENT WARNING – The laser in the vertical scanning subsystem is drawing
too little current. The laser is probably not on. This could be the result of a loss of the required set point in
memory. Have the unit checked at an authorized service center.
28
LASER #2 (RIGHT HORIZONTAL) UNDERCURRENT WARNING – The laser in the right horizontal scanning
subsystem is drawing too little current. The laser is probably not on. This could be the result of a loss of the
required set point in memory. Have the unit checked at an authorized service center.
