Checking before use
Once the battery has been installed and you have checked that the
cap and cover have been closed properly, dampen your fingers and
touch the two screws (On/Off switch contacts) and activate the
polarity circuit. You will hear a “beep” indicating activation.
If you hear a repeated “beep”, about every 30 seconds,
this means that the battery is running low. Change it.
Run another finger along the antenna. You will hear a “zzzzzz” type
sound coming from the speaker. Try to bring the antenna transducer
near the antenna on a Digital M105 unit, or the antenna on a GSM
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.
Begin speaking while holding the button down. Any units near your
CUBE³ should pick up your voice.
Put on a full-face mask so that it seals properly.
Check that there are no leaks between the edges and your face.
The CUBE³ speaker should be very close to your ear. Check that
the reception device is not too far from your ear.
Check that the microphone is installed correctly, following
the instructions above. Handle the microphone carefully.
