INTRODUCTION

The GSM CUBE³ is an underwater communication unit capable of
operating wireless, hardwired or interfaced with a VHF radio. Three
units in one!
If the unit is connected to the ALPHAPRO X-DIVERS surface unit
via cable, then communication is on full duplex with the surface unit
(no need to press the transceiver button to communicate). At the
same time the unit is capable of communicating with other wireless
underwater units such as the OCEAN REEF GSM, GSM DC, GSM
G POWER, GSM G POWER SL, M105 and M100. By pressing the
button of the PTT the unit is transmitting on channel 1 of ultrasonic
frequency (channel 1 - 31.768 kHz).
The GSM CUBE³ can be connected to a VHF radio (see page 13)
through the waterproof carrying bag and other relevant connectors
and interfaces.
The GSM CUBE³ is equipped with a special plug for the six pin
connector which can be used when the cable is not connected.
You can also connect and disconnect the unit to/from the cable
while diving.
