LUNA 2.0 AI USER MANUAL
3 .9 Warnings during diving
The LUNA 2.0 AI can alert you to potentially dangerous situations through warnings and alarms. You can modify the
warning and alarm settings in the menus or via LogTRAK.
Warnings represent situations that require the diver’s attention; however, ignoring them does not necessarily
represent an immediate risk. It is up to you to decide which ones you would like to be active.
Warnings are shown on white background in the middle of the display. Additionally, audible signals are available
when the sound function is enabled. You can also set a visual warning function, where the LUNA 2.0 AI’s display
backlighting would indicate if a warning was triggered. If this feature is enabled, the backlight will light up in bright
red color for the duration of the respective warning. Refer to chapter Setting the visual warning signal to learn
how to enable this feature.
If a warning is triggered it will be automatically shown on the display. After a couple seconds it disappears from the
screen but the diver can still review all warnings and alarms that were triggered during the dive by scrolling through
the different screens with the pushbuttons.
In the following sections the available warnings in the LUNA 2.0 AI are described.
WARNING
• When diving in GAUGE mode, all warnings are OFF except for the half tank, max depth, max dive time and pressure signal
warnings.
• When the LUNA 2.0 AI is set to silent mode (buzzer off), all audible warnings are muted.
3 .9 .1 Maximum depth
If you have enabled the maximum depth warning, the below display will be shown when the selected depth is
reached. Refer to chapter Dive depth warning to learn how to enable this warning.
3 .9 .2 CNS O
2
= 75%
The LUNA 2.0 AI tracks your oxygen uptake via the CNS O
2
clock. If the calculated value of CNS O
2
reaches 75%,
the LUNA 2.0 AI will emit a sequence of audible beeps for 12 seconds and the following display will be shown.
3 .9 .3 No-stop time = 2 min
If you wish to avoid unintentionally performing a decompression dive, the LUNA 2.0 AI can activate a warning
when the no-stop time reaches 2 minutes. This applies to both L0 no-stop and MB no-stop time (see chapter
Diving with MB-levels for more information). It gives you the opportunity to start ascending before incurring a
decompression stop or a level stop obligation.
