3. The GSM CUBE can also become a GSM VHF by interfacing it with the appropriate VHF interface and radio The GSM VHF is a very unique communication system with the integration of Ultrasonic Underwater communication features and the VHF long distance communication requirements It is mainly dedicated to Rescue Team Divers and was developed thanks to the collaboration with the Italian Red Cross The unit is comprised of a complete GSM standard hardwired to a specially modified waterproof radio carrying bag in which a number of different models of VHF radios may be inserted and interfaced It is necessary to specify the kind of radio used and OCEAN REEF will customize the required interface cabling For more information about the GSM VHF please refer to the GSM VHF manual GSM CUBE MANUAL REL 1 0 13 Instructions for underwater communication When speaking to other divers remember that they are diving It is best to attract their attention before sending a message Talking and listening while underwater requires practice With experience divers will become more proficient in the use of the communications system Speak slowly and pronounce each word clearly Only speak after having sent a call impulse by pressing the button on the microphone It is advisable to practice in a swimming pool before using the device in open water Bubbles and especially small air bubbles that are in contact with or near those communicating reduce
