ATN PS-15 Operator's Manual page 4

NOTES
• At operating temperatures below –20°C (–4°F), alkaline bat-
teries are not recommended, as operating life will be severely
reduced. Lithium-iron disulfide 1.5V AA batteries or equivalent
should be used below –20°C (–4°F).
• The IR illuminator principally serves to let you see in the
scarcely-lit surroundings at a viewing range of up to 3 meters
optimally.
EqUIPMENT LIMITATIONS
To avoid personal injuries and equipment damage which may occur
due to improper use of ATN PS15, please, carefully read and under-
stand the following safety precautions.
• The equipment requires some background light (moonlight, star-
light, etc.) to operate. The level of performance depends upon the
level of light.
• Night light is reduced by passing cloud cover, while operating
under trees, in building shadows, etc.
• The equipment is less effective viewing into shadows and other
darkened areas.
• The equipment is less effective through rain, fog, sleet, snow or
smoke.
• The equipment will not "see" through dense smoke.
