Section 2: Diving with the Monitor 3 Air

WARNING: Never allow the ATR to go below three minutes. If the ATR goes below three minutes there is a danger of insufficient air supply for the ascent as well as an increased risk of decompression sickness and serious injury or death may result.

WARNING: Correct calculation of ATR when using a reserve or “J”-type valve is possible only if the reserve lever of the valve is in the open (down) position during the dive.

WARNING: If the ATR drops below three minutes, an acoustic attention signal sounds at the ATR digits start to flash.

WARNING: When the last minute has passed (ATR=0) an acoustic alarm is activated every 4 seconds. The digital ATR and graphical ATR start to flash. Start your ascent immediately!

Note: The acoustic alarm on exceeding the ATR is suppressed at depths less than 23 feet if the Monitor 3 is in a no-decompression stop phase.

High Air Consumption Warning

The high air consumption warning appears when you significantly increase your breathing rate. This could be the result of sudden physical effort, emergency situation, or significant leak in the air supply. When this symbol appears, reduce exertion and breathe more slowly.
