Installation
Carefully read this chapter before installing the system. We list rules and
recommendations for installing and connecting your scanner.
!
•
WARNING: Do not make any other adjustments to the
equipment than those specified in this manual.
•
WARNING: If at any time during operation an intense dot
of light is generated instead of a thin line of light,immediately
turn the laser off, using the toggle switch on the back of the
scanner, then remove power to the decoder.
CAUTION: Do not look directly into the laser beam. It could
damage your eyes.
!
WARNING: No user maintenance of the hardware is required.
Do not open the unit’s housing!
The angle and distance between the scan head and the label is an important
consideration. These considerations, orientation and alignment, are
described in Chapter 3, Installation Considerations.
Normally, the only tools you will need for installation will be the adjustment
tool supplied with your scanner. If the optional Swivel Mounting Base and
Plate are used (Catalog No. 2755–NM1 and 2755–NM2), you will also need
a screwdriver and a
3 /
16
–inch Allen wrench.
