FREE DIVE ALARMS
FREE mode alarms, which are separate from NORM (or GAUG) alarms, sound either 1 or 3 times as 3 beeps then clear. They
cannot be acknowledged or silenced.
CDT Alarm
When a set Countdown Time reaches 0:00, the audible will sound during which time the graphic CD will be displayed with 0:00
(min:sec) flashing on the Main (Fig. 116). If Temperature and EDT are on the Main, CDT replaces them during the audible then
they are restored.
EDT Alarm
When set On, the EDT alarm activates every 30 seconds during a dive. The audible will sound during which time the EDT digits
will flash on the Main (Fig. 117). If the CDT is on the Main, EDT replaces it during the audible then the CDT is restored.
Depth Alarms
When set On, the Depth alarms (1, 2, 3) activate at their respective set Depths. The audible will sound during which time the
graphic D1 (or D2, D3) will be displayed in place of Temperature or the graphic CD with the Depth digits flashing on the Main
(Fig. 118). After the audible is silent, Temperature or the graphic CD will be restored.
High Nitrogen Alarms
When nitrogen increases to the caution level (14 TLBG segments, 70%), the audible will sound during which time the TLBG seg-
ments will flash on the Main (Fig. 119).
In the event that nitrogen continues to increase and reaches the Deco level, the audible will sound again during which time all 20
segments of the TLBG, the Up Arrow icon, and the graphics UP and VIO will flash (Fig. 120).
When the audible is silent, the TLBG will be removed, the graphics and Arrow icon will continue to flash until on the surface, then
UP and the Arrow will be removed.
The graphic VIO flashes until 1 minute elapses on the surface, then it alternates with FRE and operation reverts to Violation
Gauge Mode for 24 hours.
