speaker.

Bring the antenna transducer near the antenna of another active unit (about 5 cm / 2 inches),
keeping your fingers on the On/Off contacts. You should also be able to hear the communication
when the unit is not immersed in water.
Pushing the PTT button you will hear a
“beep”

the PTT button pressed and check that the other unit is receiving.
Do the opposite operation to check the receiving of your GSM Mercury.

Flip and hold for two seconds the level style button, you will enter the “program mode”, check
the settings of your unit and exit by following the instruction at page 6.
If you need to use the D.A.T. mode remember that only one diver per time should use
the DAT mode!
Disregarding this direction will cause communication to be confused and useless.
A repeated voice signal
“Battery Low”
(about every 30 seconds) means that the
battery is running low. You still have about 2 hours depending on your use prior to
recharge.
