Section 5:Helpful Hints - OTS Aquacom MK2-DCI User Manual

1) Before diving operations begin, check to be sure the microphone, earphones,
and wire connections are secure and operating properly. Ninety percent of all
problems in communications turn out to be a problem with one of the above.
2) When in the four-wire mode, you must use a headset with a boom microphone,
and the Diver Select switch must be in the "BOTH" position. If feedback is
present, switch off the front panel speaker (Fig. 1, #24).
3) Avoid excessive tender-to-diver volume. Most of the time, when there is too
much volume, the diver will hear distortion and ask for more volume!
4) Before diving operations, always check the battery power level, and replace or
recharge the batteries if necessary.
5) Make certain the headphone and remote PTT plugs are securely inserted into
the proper receptacle.
6) When in the four-wire mode and a wire breaks, try setting the system up in the
two-wire communication mode (Fig. 2), and continue diving operations.
7) Secure the MK2-DCI if using the unit on a vessel that is rolling about. Also
strain-relief the umbilical(s) so they will not pull on the MK2-DCI.
8) Ensure the umbilicals are dressed out so as not to trip anyone.
