Once completed the GWX70 Weather Radar installation, the following procedures must be accomplished: electrical test, software upload and functional test on ground. WARNING This radar device produces microwave radiation. Do not operate this device until all safety precautions and instructions herein and in GWX 70 Weather Radar Installation Manual have been read. Improper use or exposure may result in bodily injury. WARNING All personnel should remain the prescribed Safe Distance from this radar. Never expose any part of the body to an unterminated waveguide. The minimum Safe Distance is the semi-circular area Page 12 of 23

13 within a radius of 11ft from the GWX 70 Weather Radar 10 Antenna. All personnel and fuel tanks, must remain outside of this zone. Begin Radar transmitting only when it is safe to do so. WARNING Airborne weather radar should be operated on the ground only by qualified personnel. WARNING Installed airborne radar should not be operated while the aircraft is in a hanger or other enclose unless the radar transmitter is not operating, or the energy is directed toward an absorption shield which dissipates the radio frequency energy. Otherwise, radiation within the enclosure can be reflected throughout the area. WARNING To prevent possible human body damage, the following precautions should be taken: 1. Personnel should never stand nearby or in front of a radar antenna which is transmitting. When the antenna is not scanning the danger increases. 2. The recommended Safe Distance which is previously established should be followed. The distance from any person to the radar should be greater than the recommended safe distance. 3. Personnel should be advised to avoid the end of an open waveguide unless the radar is turned off. 4. Personnel should be advised to avoid looking into a waveguide, or into the open end of a coaxial connector or line connector to a radar transmitter output, as severe eye damage may result. 5. Personnel should be advised when high power radar transmitters are operated out of their protective cases, X-rays may be emitted. Stray X-rays may emanate from the glass envelope type pulser, oscillator, clipper, or rectifier tubes, as well as magnetrons. To prevent possible fuel ignition, an installed airborne weather radar should not be operated while an aircraft is being fuelled or de-fuelled. Page 13 of 23
