Standby-mode:
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 pressure transmitter returns to transmis-
sion-mode.

pressure transmitter will start working when the tank valve
is first opened or when gas mixture is drawn through the regulator.
The pressure transmitter will not work if either the tank valve is turned off and
the regulator purged or if no gas mixture has been drawn through the regula-
tor for a period of three minutes.
2.2 Oxy2 operating modes and functions
Switching on:
The Oxy2 can be switched on and off manually or automatically by dipping into
water.
Checking:
Before each dive the Oxy2 has to be checked and a calibration may be required
(see Oxy2 Manual).
Calibration:
The turnable switch has to be turned from position „RUN“ to „CAL“ and after
completing the calibration back to „RUN“ (see Oxy2 Manual).
Pair-mode:
A pairing is necessary every time you change from pressure transmitter to Oxy2.
The Oxy2 sends a pairing data string at the beginning of the battery and O

sensor lifetime check, just after the Oxy2 has been switched on. For detail on
Oxy2 pairing see page 38.
Transmission:
For as long as it is switched on and the switch is in „RUN“ position, the Oxy2
transmits at approximately every 5 seconds the measured oxygen fraction.
Switching off:
The Oxy2 automatically switches off if a dive as not commenced within 30 minu-
tes of either switching on the Oxy2 or a recalibration was done. After a dive it
switches automatically off after 15 minutes.
