THE TRANSMITTER
The compact transmitter module screws into a standard
7/16" HP port. The transmitter automatically activates when it senses pressure from the cylinder. Once activated, it sends pressure information via a low frequency radio wave to the wrist unit.
One of the unique features of the transmitter is that it sends along a special code each time it transmits pressure information. The computer "listens" to the code, and, if it is the correct code, accepts the pressure information. This feature allows more than one Monitor 3 Air system to be used without information becoming mixed up, i.e. you reading your dive buddy's air information.
