WARNINGS, CAUTIONS, NOTES Pay special attention when accompanied by these symbols: A WARNING indicates a procedure or situation that, if not avoided, could result in serious injury or death to the user. A CAUTION indicates any situation or technique that could cause damage to the product, and could subsequently result in injury to the user.
(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).

DIN connection for the transmission and microphone button and two quick connections. For optimum functioning we recommend using the unit on OCEAN REEF Space masks, as the unit’s acoustic characteristics are designed to suit these masks. How to install the NACS...
Installing the microphone The CUBE³ uses a dynamic microphone, ”D-Mic” encapsulated and protected by a hydrophobic membrane. The microphone allows dependable clear reproduction of the human voice. It removes unnecessary noise such as the noise of bubbles being exhaled from the mask. The D-Mic uses a hydrophobic membrane that allows air to pass through while protecting the microphone from water.
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.

When the battery has been installed, check that the battery housing and O-ring are clean. The O-ring must always be lubricated with a thin layer of silicone lubricant. (5) Holding the cap in position, position the cover and screw the two screws in place until they are tight.
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.
Functioning of the GSM CUBE³ with the ALPHA-PRO X-DIVERS The GSM CUBE³ is made to allow the connection to the ALPHA- PRO X-DIVERS. You can connect the CUBE³ to the cable outside or inside the water; simply take away the plug from the 6 pin connector and plug it into the ALPHA-PRO X-DIVERS cable.
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.
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.
PRECAUTIONS Do not use solvents (such as diluents) to clean the unit. They can cause irreparable damage. Only use neutral detergents. Use running water to remove the seawater from your GSM CUBE³ after use. The system must be kept completely dry and in good condition.

Routinely clean the microphone contacts and check the integrity of the hydrophobic membrane and the case. If the microphone is flooded, it CANNOT be recovered and must be replaced. Do not touch the hydrophobic membrane with any sharp objects that may damage it.
Warranty (1) OCEAN REEF communication units are guaranteed to be free of material or manufacturing defects for a period of 24 months from the time the unit is purchased. For the duration of the guarantee, the Company’s responsibility is limited to replacement of any parts that are defective in our opinion, and that have not been used incorrectly or handled negligently.
TROUBLESHOOTING Problem Possible cause action The unit does not The battery is Insert a charged switch on (it still missing, the contacts battery. Remove works via cable) are isolated, the isolation caps battery is dead The polarity is Insert the battery inverted.
