Display Replacement
IMPORTANT: The display is not waterproof and
should not be exposed to rain, snow, or moisture.
Under extreme conditions, water may enter the
circuitry through the panel buttons. In general, treat
the display as you would a pocket calculator or other
small non -waterproof electronic instrument.
IMPORTANT: The Bendix ® XVision ® Night Vision
System display technology is designed to meet
severe temperature extremes. However, when
installing the display for head-down operation or
for use in extremely warm climates, take necessary
precautions to shield the unit from direct sunlight.
Prolonged exposure to direct sunlight in enclosed
truck cabs can damage the system.

Table 5 on Page 7.

screws will form the threads on the standoffs as
they are tightened. If it feels as though the screw is
binding, back out the screw slightly and continue to
tighten to prevent breakage.
