Section 2: Diving with the Monitor 3 Air

WARNING: There is an acoustic alarm if no-stop time is less than one minute. In this last minute, the no-stop display shows a flashing 0. In order to prevent a decompression dive, you must ascend immediately.

WARNING: It is unsafe diving practice to “push” the Monitor 3 Air, or any other decompression tool, to its limits. Avoid no-stop times of less than 3 minutes at any given depth.

Cylinder Pressure

Cylinder pressure is displayed in pounds per square inch (psi) in 1 psi increments.

If, during the dive, there is an interruption in the transmission of air data to the Monitor 3 Air for more than 30 seconds, the antenna symbol

will appear, accompanied by an acoustic warning. If sensible data is not received within 40 seconds after the antenna symbol appears, the air pressure reading will be replaced by four dashes, and all air time informa- tion will disappear. The most likely cause of transmission interruption is the position of the computer in

relation to the transmitter. As soon as data is transmit- ted again, the computer will display the cylinder pressure and air time information.
