Owner's Manual blood pressure monitor

Section 2: Diving with the Monitor 3 Air
22
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.
