EQUIPMENT LIMITATIONS
To avoid physical and equipment damage when using the
ATN PS28, carefully read and understand the following equip-
ment limitations.
• The equipment requires some night light (moonlight, starlight,
etc.) to operate. The level of equipment performance depends
upon the level of light.
• Night light reduces by passing through the clouds, while oper-
ating under trees, at building shadows, etc.
• The equipment is less effective when viewing into shadows
and other darkened areas.
• The equipment is less effective when viewing through the rain,
fog, sleet, snow or smoke.
• The equipment will not “see” through the dense smoke.
