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 XVision
®
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.
CB Style Mount (Dashboard and/or Overhead)
1. Unscrew and disconnect the 25-pin connector of the
display harness.
2. Unscrew the threaded knobs from the display and
brackets. Refer to Figure 30. Set the knobs and
washers aside.
3. Remove the old display.
4. Set the DIP switches on the new display according to
Table 5 on Page 7.
5. Slide one of the washers onto one of the threaded knobs.
6. Hold one washer between the new display and a bracket
while threading the washer/knob from the outside of the
bracket. Refer to Figure 30 on Page 15.
7. Repeat steps 5 and 6 for the other side of the display.
8. Plug the 25-pin connector of the display harness into
the new display.
Friction Hinge Mount (Visor)
1. Disconnect the 25-pin connector of the display harness.
2. Flip the display down to allow access to the friction
hinge supports.
3. Remove the four #10 Plastite
®
pan head screws that
secure the display to the headliner.
4. Remove the old display.
5. Remove the two M2.5 threadroll pan head screws that
secure the friction hinge supports to the display.
6. Secure the friction hinge supports to the new display
with the two M2.5 threadroll pan head screws.
IMPORTANT:
Do not exceed 15 in-lbs. when
fastening. If 15 in-lbs. are exceeded, the screw head
will shear off or the stand-offs will strip. The threadroll
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.
7. Secure the friction hinge supports to the headliner with
the four #10 Plastite
®
pan head screws.
8. Torque the screws to approximately 15 in-lbs.
9. Connect the 25-pin connector of the display harness to
the new display.
