1 . TECHNICAL CHARACTERISTICS
Main parts of the unit are:
• Battery housing: inside the battery housing there is a label with the serial
number and the polarity to insert the battery. Battery should be a 9volt alkaline
one, rechargeable batteries will last shorter. The autonomy with the alkaline
battery (receiving mode) is around 30 hours with 30 minutes of low battery
alarm (one "beep" every 30 seconds)starting when voltage goes below 6.8volt.
• Antenna: it is a ceramic one, made to transmit and receive
ultrasound to a frequency of 32.768 kHz (UCF).
• Wet contact screws: the unit is turning automatically on when it is submerged
into the water, to perform a dry test is possible to turn it on using the fingers.
• PTT & MIC: PTT button is a magnetic one. The D-Mic is a dynamic
(see following specs). The PTT & Microphone assembly is connected to
the main unit with 30cm (1 ft) of polyurethane reinforced cable.

OCEAN REEF patented support to hold the communication
unit in position making the mask more comfortable.
• Range of operation 200-250m in calm water. (This may vary due to
