At power-up, all the controls should be in the minimum (far left) position. Have the
diver speak and adjust the DEPTH CONTROL as necessary to achieve the best
speech quality. Then adjust the TREBLE BOOST as necessary to improve the
quality. There is some interaction between these controls so you may have to go
back and adjust the DEPTH CONTROL. Once the best speech quality settings are
found, the NOISE REDUCTION FILTER can be adjusted, if necessary, to reduce
any background noise.
Operating in 2-Wire and Full Duplex (4-Wire) modes are possible with the HSU. In
2-Wire mode, the tender's push-to-talk switch interrupts signals from the diver. In
Full Duplex mode, the tender will hear the diver at all times and tender must use a
headset to talk to the divers without using the push-to-talk switch. Use of a headset
to monitor helium speech is strongly recommended to enhance intelligibility.
