Procedure for assembling the PTT & D-mic
• Unscrew the communication port plug (labelled
COMMUNICATION), insert the PTT & microphone through the
mask into the “communication” port with the hydrophobic
membrane facing the visor.
• If the membrane is turned the wrong way, facing the mouth,
phonic performance will be diminished. Check that the
microphone is in the position shown in pictures. Move the
microphone so that it does not interfere with the diver’s lips or
the pressure compensation bracket.
Installing the battery
GSM CUBE³ (when used via wireless) works with a conventional 9V
alkaline battery.
Do not use manganese batteries.
(1) Unscrew the two screws on the cover and remove the cover and
cap with its O-ring.
(2) Remove the dead battery from the main compartment.
(3) Install a new battery in the compartment,
making sure that the polarity is correct (see label
on the inside).
(4) Clean and lubricate the O-ring. Reposition the
cap. The cap MUST face the right direction. The flat
side of the battery cap must be on the front side in
order to get a good seal.
