Operation is completely wireless via the included wireless remote control. It is guaranteed to be waterproof up to 100 metres, as are the vest and batteries. No additional cables are needed. The remote control can be worn on the wrist or secured elsewhere on the equipment. Holding down the button on the controller for 3 seconds will switch the system on (make sure that the batteries are also individually switched on, otherwise the system will not work!) A vibration signal will be felt on the belly when the system is switched on. By repeatedly pressing briefly on the button of the remote control, the heat level can be changed. Each time, a corresponding vibration signal can be felt. By pressing and holding the button again for at least 3 seconds, the system will switch off and a long vibration signal can be felt on the abdomen.
If desired, the system can be switched on on land and the remote control left on shore while the diver goes underwater with the activated system.
