– The RBT must never reach <0:> (alarm signal), because a minimal reserve
pressure at the surface would not be guaranteed. Danger of insufficient air
supply for the ascent!
– Correct calculation of the RBT is only possible if the valve of any reserve
function is open during the dive.
– The acoustic alarm on exceeding the RBT is suppressed at depths less
than 7 m if Aladin
®
Air Z is in the no-stop phase.
Messages:
– If the RBT drops below three minutes, an acoustic attention signal is
activated and the RBT (only figures) starts flashing.
– When the last minute has passed (RBT=0) an acoustic alarm is activated
every 4 seconds. The RBT is flashing.
Procedure: Start ascent at once.
