CHAPTER 3:
OPERATING INSTRUCTIONS
3.1 Introduction:
This chapter contains instructions for the safe operation of
the DTNVS under normal circumstances and
environments.
3.2 Controls and Indicators:
The DTNVS is designed to adjust for different users and
corrects for most differences in eyesight. The controls and
indicators for the DTNVS are shown in Figure 3-1 and are
described in Table 3-1.
CAUTION
The DTNVS requires some ambient (moonlight,
starlight, or artificial light, etc.) to operate. The level
of
performance depends on the level of light.
Night light is reduced by passing cloud cover, while
operating under trees, in building shadows, etc.
The DTNVS is less effective viewing into shadows and
other darkened areas.
The DTNVS is less effective through rain, fog, sleet,
snow, smoke, and other reflective material.
