TM 1–1520–238–T–1 Change 6 3–3 3–1 SYSTEMS – POWER–UP (cont) 3–1 WARNING DANGER laser light · The TADS has a hazardous class IV neodymium laser. The laser emits a light beam with a light wavelength of 1064 nanometers and is invisible. Accidental application of laser power could result in direct exposure to the invisible beam or reflections from the beam. This could cause blindness or serious eye injury. · To prevent accidental APU start, ensure that the APU circuit breaker in the AFT avionics bay and the APU HOLD circuit breaker on the pilot center circuit breaker panel are open when battery or external electrical power is attached to the helicopter and unqualified personnel are in and around the pilot crew station. · Prior to helicopter operation, ensure that the gun turret area is clear. Failure to clear the area could result in injury to personnel or damage to equipment. CAUTION · If ambient outside temperature is below 18°C (0°F) or above 27°C (80°F) make sure the environmental control system (ECS) is ON. Allow pilot and copilot/gunner (CPG) crew stations to reach a comfortable level before proceeding. Failure to comply could result in damage to equipment
