ATTENTION: If during operation an intense dot of light is
generated instead of a thin line of light, immediately remove
power from decoder and replace the scanner.
CAUTION:
Do not stare into laser beam to avoid damage to your eyes.
!
ATTENTION: The scanner contains no user-serviceable parts.
Laser safety regulations require that only people with the proper
training can open the housing.
Laser On Indicator
Laser light is difficult to see. The front window of the scanner contains a Red
LED to warn the operator when the laser is ON.
Turning the Laser Beam ON and OFF
The 2755-DS1A and -DD1A Enhanced Decoders have controls that allow
the laser to be:
•
ON continuously
•
triggered ON by the package sensor
Note: In this mode, assume that the beam from the package sensor to
its reflector could be interrupted at any time, which will turn the
scanner ON until the symbol is decoded.
•
always OFF: used during maintenance so it cannot turn ON accidentally
and damage someone’s eyes.
Note: If the scanner is OFF, do not assume that it is in this mode.
Verify the decoder control setting each time you set up or adjust the
scanner.
This control is accessed through a standard computer terminal or personal
computer with a terminal emulator. See the Enhanced Decoder Manual
(Publication No. 27550-833) for more information.
