NOTE:
Your speech should be considerably slower than normal, and each word should be
pronounced clearly and distinctly. Speak one word at a time instead of in owing
sentences. Do not shout, but use slightly loud conversation volume. Minimize
exhalation while speaking. Your communication will be more easily understood
if you are relaxed, since speech is less intelligible when a diver is anxious.
You should conduct a pool checkout and have more pool practice before using
the system in open water. While Magnacom
®
transceivers provide divers with
good underwater communications, they do not change or eliminate the potential
hazards of diving!
CAUTION: Use any standard safe entry into the water, but be aware of the
additional equipment you are wearing. The transceiver and cables should be
positioned so they do not snag or hit against anything during entry. Keep a copy
of this checklist handy for reference before entering the water.
3.8 RECEIVING A MESSAGE
3.9 DOFFING THE DIVER UNITS
1. Disconnect the Hi-Use
®
connector from the full-face mask, HM-2 mouth mask,
or LAR V Adapter. Doff the rebreather.
2. As soon as possible after each dive, rinse the unit in freshwater to remove salt
and other mineral deposits.
3. Although the SW-1000-SC is ruggedly constructed for long life in the marine
environment, we strongly recommend that you place it in a protective carrying

Relax
Concentrate on hearing.
Try different earphone positions until the best one is found.
Minimize exhalation bubble noise, but do not hold your breath. Most divers nd
that an inhalation cycle is the best time to receive a message. While off-gassing,
the bubble noise makes hearing difcult (with open-circuit scuba).
3.7 SLEEP MODE
Disconnecting the e/m harness (cable) from the transceiver, with the transceiver
remaining under water, results in the transceiver entering “Sleep Mode.” During
this mode of operation, battery consumption is dramatically reduced—allowing
the swimmer to exit the water or perform other operations not requiring through-
water communications. The transceiver “wakes up” upon re-connection of the
e/m cable and returns to normal operation. The remaining amount of operational
time depends on the state of charge before the Sleep Mode was activated and the
length of time the transceiver had been in Sleep Mode before re-activation.
