OPERATE AN/VAS-5 DRIVER'S VISION ENHANCER (DVE) (M58 ONLY) -- Continued
0035 02
NOTE
The time necessary for the system electronics to stabilize depends on ambient temperature. As
ambient temperature rises or cools, the stabilizing time changes slightly.
The words "NO SENSOR VIDEO CHECK VIDEO SWITCH" will appear on the display
only if the VIDEO switch is in the EXT position or the display circuitry has no video input. If
the video returns, the words are removed.
2.
Set POWER switch to ON (up position). The power light-emitting diode (LED) will illuminate. Allow five minutes for
system electronics to stabilize for maximum image clarity.
3.
Leave the VIDEO switch in the SENSOR (up position) for sensing input from the sensor to the display. For external
input to the display, set switch to EXT (down position).
4.
Adjust the seat height and/or Display Module to place the display at eye level. Loosen the two display adjustment
knobs on both sides of the Display Module. Adjust the tilt of the Display Module either up or down. Retighten the
adjustment knobs.
WARNING
If the display becomes degraded while driving the vehicle, such as the presence of dead pixels
(the very small dots that make up the display image) and/or video noise that prevents the driver
from performing his mission, then immediately bring the vehicle to a safe stop to avoid collision.
If the problem cannot be fixed, report the situation to higher level maintenance.
NOTE
The DISPLAY BRIGHTNESS control should not be adjusted too high (saturated) or too low,
or the scene may be uncomfortable to view and some useful video information may be lost.
Also, with the control adjusted too high, you may reduce your eye's night vision capability
and compromise light discipline.
If the ambient light within the vehicle changes, it may be necessary to compensate by
readjusting the DISPLAY BRIGHTNESS control.
5.
DISPLAY BRIGHTNESS Control -- While viewing the display scene, adjust DISPLAY BRIGHTNESS control until
scene brightness is suitable for operator viewing. It may be helpful to readjust the Display Module tilt and/or seat
height for best viewing.
