DIVE MODE

Prior to the first dive of a new series, if Wet Activation is set Off, Dive Mode will not activate during operation in any Watch Mode.  

It must to be in FREE Mode prior to activating Dive Mode.  

If Wet Activation is set On, Dive Mode will activate from any operating surface mode including Watch modes once the A/d senses 

the DSD (Dive Start Depth) set for 5 seconds. 

Once the first dive of a series is completed, repetitive dives will be activated regardless of what surface operating mode it is in. 

Dives start upon descent to the DSD (Dive Start Depth) set (0,6 , 1,2 , or 1,8 M; or 2 , 4 , or 6 FT) for 1 second and end upon 

ascent to a Depth <  0.6 M (2 FT)** for the BDSI (Between Dive Surface Interval) time set, thus descending before the BDSI time 

elapses is the same dive and descending at => the BDSI is a new repetitive dive. 

**Upon ascent to < 0,6 M (2 FT), the Dive Main will display 0,0 M (0 FT) until you surface or descent is made to the DSD 

set during the BDSI.

BACKLIGHT

cally after 10 seconds.  If it is already On, it will remain On for 10 seconds from the time that the Alarm strikes unless you turn it Off 

during that 10 second time.

After the first

•  S (< 2 sec) - to save Lap 1’s time and display the graphic LAP2 with the Timer continuing to count up.  

Total Run Time is always 

displayed until stopped. 

•  S (< 2 sec) - to save/display other Laps in progress up to # 9.  

>> Subsequent Laps continue to be recorded with the earliest being discarded after 9, starting again with #1.
