Precautions
Observe the following precautions for your safety and the safety of your A704-5
Wireless Lighting System.
2.1 Viewing
Precautions
Infrared Light Emitting Diode (LED) Viewing
Do not view a Model A704-5 actively emitting infrared or visible light from the side of
the light (close to or on beam) from a range of less than 4 feet (1.2 meters). Please see
the following diagram for further details.
A safe limit for near-infrared viewing, established by the American Conference of Governmental and
Industrial Hygienists (ACGIH), is 65mW/in
2
(10mW/cm
2
) as the maximum exposure limit for viewing for up
to 16 minutes. This power density can be produced by a Model A704-5 at the lens surface when actively
emitting infrared light. High-power visible-spectrum LEDs also pose an eye safety risk if viewed
inappropriately.
Figure 2-1: LED Viewing Precautions
2.2 Battery
Precautions
Use extreme caution when handling the light. This product is capable of generating
enormous short-circuit currents. Remove all jewelry (bracelets, metal-strap watches,
rings) before attempting to handle or remove the batteries.
Take care when connecting or disconnecting cables. A damaged cable can cause
problems with the electrical circuit. For instructions on disconnecting and reconnecting
the batteries within the light, see Appendix A: Battery Replacement.
