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.
FREE CDT Alarm
When a set Countdown Time reaches 0, the audible will sound during which time the graphic CDT will be displayed with 0 min
flashing on the Main (Fig. 147).
FREE 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. 148).
FREE 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 DA1 (2, 3) will be displayed with the Depth digits flashing on the Main (Fig. 149).
High Nitrogen Alarms
When nitrogen increases to the caution level (4 TLBG segments), the audible will sound during which time the TLBG segments will
flash on the Main (Fig. 150).
In the event that nitrogen continues to increase and reaches the Deco level, the audible will sound again during which time all 5
TLBG segments and the graphic VIO will flash (in place of Temperature), and NDC will be removed.
When the audible is silent, the TLBG will be removed, the graphic UP will alternate with VIO (Fig. 151) until on the surface, then
UP will be removed.
The graphic VIO flashes until 1 minute elapses on the surface, then it shifts upward and alternates with FRE (Fig. 152) and opera-
tion reverts to Violation Gauge Mode for 24 hours.
