3.4 INHALATION NOISE REDUCTION CONTROLS
Amron’s INR module features an individual inhalation noise reduction circuit for each diver
that can eliminate inhalation noise completely or suppress the inhalation noise to the degree
the operator demands. The net result is improved communications and intelligibility between
the tender and divers.
3.4.1 INR LED INDICATOR – Located in each diver’s section next to the INR control
knob on the front panel and will illuminate blue when the unit is attenuating the
diver’s inhaling noise.
3.4.2 INR CONTROL KNOB - Located in each diver’s section next to the INR LED
Indicator on the front panel and used by tender to control the level of inhalation
noise reduction.
