LUNA 2.0 AI USER MANUAL
WARNING
If the RBT drops to 3 minutes or less, you may not have enough gas supply to complete a safe ascent. Start ascending when
you see this warning.
3 .9 .10 Pressure signal
If the LUNA 2.0 AI receives no signal from the transmitter for 70 seconds, an audible sequence goes off and the
message BAD SIGNAL appears on the display for 12 seconds. After 30 seconds without receiving signal the LUNA
2.0 AI emits another audible sequence and the message SIGNAL LOST appears on the display, after which the
tank pressure is replaced with - - -.
In the event of a “signal lost” situation, all tank pressure-related information on the LUNA 2.0 AI ceases to be valid.
In such a case, you must use a backup instrument for pressure monitoring and seek a safe ascent to the surface.
Running out of gas under water is dangerous and may lead to severe injury or death by drowning.
3 .9 .11 100/100 no-stop = 2 min
When diving with GF setting other than 100/100, the underlying 100/100 information is not directly visible on the
display (though it is accessible as alternate information). You can choose to have your LUNA 2.0 AI warn you when
the underlying 100/100 no-stop time reaches 2 minutes while diving with an active GF setting other than 100/100.
3 .9 .12 Entering GF stops
When diving with a GF setting other than 100/100, the LUNA 2.0 AI can warn you when you are no longer in the
GF no-stop phase. For more information, see chapter Diving with Gradient Factors (GF).
