mode setting, the frequency shifting algorithm’s function will automatically
change as well.

NOISE REDUCTION FILTER (NRF): Incorporates a complex DSP algorithm
which filters out background noise while allowing the diver’s speech to be clear
and intelligible. Amron NRF automatically captures the frequency spectrum of
applied background noise within the audio frequency bandwidth and reduces it
without affecting the diver’s speech. The NRF has four adjustment levels for the
reduction of background noise in both depth modes A & B. When in mode A,
simply toggle the Mode Switch from A to B and back to A. In mode B, simply
toggle the Mode Switch from B to A and back to B. Each time a toggle cycle is
completed, the filter will advance to the next level. Based on the filter level, the
operator will hear a number of beeping tones from 1-4 that corresponds with the
blue LED indicators.

NRF INDICATOR: There are four blue LED indicators that correspond to the
present setting of the noise reduction filter ranging 1-4.
