The Active Noise Reduction Pilot Headset is a headset that can isolate, offset and cancel noises. In comparison with conventional headsets, it can, under noisy circumstances, provide a quieter and more comfortable sensation, by reducing background noise. Therefore, make it possible to improve the telecommunication quality and articulation, resulting in a higher operation safety factor. The noise cancelling circuitry reduces outside noise considerably more than a standard headset, making it more comfortable for the pilot in the aircraft. HEADSET OPERATION 1. Rotate the flexible boom overhead...

NOTICE： 1. This ANR headset can only work when the plug is connected with the running aircraft equipments or intercoms. The power of ANR function comes from 9V battery, not equipments or intercoms. 2. When the battery power is low, the red LED indicator will flash. Note that the headset will continue to operate as a normal headset under low battery power or no battery power; however the active noise reduction will cease to operate after one hour. Cautions: 1. Proper Fit: Proper fit is critical to its noise attenuation effectiveness. i. Push the headband down until it rests comfortably on...

HEADSET NOISE ATTENUATION DATA The noise reduction or attenuation characteristics of communication headsets must be measured according to an accepted standard procedure if the characteristics of different headset are to be compared in a meaningful way. The Noise Reduction Rating (NRR) is provided in accordance with U.S.EPA Regulation 40 CFR Part 211.Subpart B. The Range of Noise Reduction Rating for Existing Hearing Protectors is approximately 0 to 30. (Higher Numbers Denote Greater Effectiveness) Frequency [Hz] Standard Deviation Specifications Noise Reduction Ratings（NRR） 24dB ： Headphone...
