When the regulator is unpressurised the transmitter is in the off-mode. In that
case, air pressure is measured every 5 seconds. When pressure increases (on
opening the valve), the transmitter leaves the off-mode automatically. When
the tank valve is closed and the regulator inlet pressure is reduced to below
8 bar, the transmitter falls back into off-mode.
After switching on (opening of the tank valve), the transmitter sends its address
to the dive computer for a short time. This is the code in order that the dive
computer can be paired to the transmitter.
As long as tank-pressure is decreasing (during normal breathing) the pressure
is transmitted to the dive computer on average every 5 seconds.
If there is no decrease in tank-pressure (no breathing), the transmission is stop-
ped after 3 minutes in order to save energy. Pressure measuring continues.
As soon as breathing is resumed, the transmission also starts again – the trans-
mitter returns to transmission-mode.

without transmitter
The transmitter starts working if the tank valve is
opened or when air is consumed on breathing.
The transmitter does not work if the regulator is un-
pressurised or if there is no air consumed for 3 mi-
nutes.
The dive computer can only receive data from the
transmitter if the computer and transmitter are
paired. If the pairing has not been carried out, there
are no air data displayed by the dive computer and
Aladin ® Air Z works as a conventional dive computer.
