NicePower AN-1000AC Active noise cancelling General Aviation Headset (green)

MIND: this lheadset is presented and delivered in plastic bag! Not in a box.

The Active Noise Reduction AN-1000AC ANR Headset is a headset that can isolate, offset and cancel noise. In comparison with passive headsets, it can, under noisy circumstances, provide a quieter and more comfortable sensation, by reducing background noise. Therefore, make it possible to improve the audio 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 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] 125 250 500 1000 2000 3000 4000 6000 8000
Attenuation [dB] 14.3 21.5 27.1 31.8 36 39.5 41.3 39.7 37.0
Standard Deviation 3.3 2.4 1.5 1.6 1.3 2.1 2.1 2.0 1.3

NOTICE: ANR BATTERY MODULE OPERATION

1. The battery module requires two AA battery. The power of G2 ANR comes from AA battery, not aircraft power.
2. Figure 1: There are on/off switch, and Led light on the top of battery box.
A. When the switch is on (I), the Led will be on and the ANR function starts working.
When the switch is off (o), the power for the battery box is shut off and the ANR function stops working.
B. The Led is green when the power is on and the batteries are fully charged. The led turns red when the batteries are low.
3. Battery changing: move the clip to the left or right; press the opener and push it out; put the batteries in according to the "+""-" signs inside; put the opener on and push it back. See figure 3.

To save on batteries, pls shut off the power when the headset is not in use.
