The Heads-up display (HUD) works in-conjunction with the Primary
display and uses four LED lights to warn the diver of the
changing status of the unit. The different colour LEDs correspond
to different groups of Alarm types. As a basic rule, a Flashing
LED is a warning. A static ‘on’ or ‘off’
LED is an OK condition. A fast flash indicates a different
Alarm state to a slow flash. As there are many combinations,
the diver should use the HUD in combination with the primary
display. When the primary display is in the Main Dive Screen,
the top right corner of the display will give an indication
of the highest priority Alarm, which will correspond to a
flashing LED on the HUD.
In the case of more than one Alarm state, the diver should
look at the Sum – (Summary) screen to get more information.
An alarm status will also actuate a vibrating action throughout
the mouth piece.

(2005) incorporates a vibrating mouth peice warning signal
as well as lights.
Above; Here the Alarm and
Oxygen signal lights actuate.
From the Sum – (Summary) screen,
the diver can also deactivate the vibration alarm that comes
on when major alarms are detected, however the HUD light will
not turn off. The only exception to this is the Absorbent
remaining alarm which can have both indicators turned off
but will reactivate both after 30 minutes.
The table below gives the Alarm types
indicated by the HUD.
Alarms
will occur on the Primary display and the HUD.
The HUD will give a visual (flashing light)
and a tactile/audible warning (it vibrates).
The HUD will vibrate until the alarm function
either corrects itself, you correct it or you
turn off the vibration function for that alarm.
You can turn the function off by going to the
first page of the SUM screen and turning off
the music note (short push, right button). If
the vibration continues then something else
is still in alarm. Visual alarms cannot be turned
off. If you turn off the vibration alarm for
the ‘stack low’ alarm it will automatically
reactivate every 30 minutes. The HUD white alarm
light will also be turned off for 30 minutes.
The first screen entered shows the first page
of current alarm conditions.
• To move between pages, use a short press
of both buttons.
• To disable an alarm from activating
the HUD vibration motor, use a short press of
the right button to toggle the mode on and off.
You will notice the music note symbol disappears.
Visual screen and HUD alarms will still be apparent.

categories, and the specific alarms in each
