Understanding the Diving Mode Screen
The Surface screen appears while you are on the surface, while the
Submerged screen appears while you are submerged.
The dive time value shows the elapsed time you spend submerged.
Pressing C while the Surface screen or Submerged screen is on the
display changes to the Maximum Depth screen for about three seconds.
The dive start time shows when your dive first reached submerged depth
after you entered the Diving Mode.
The maximum depth value shows the maximum depth you reached during
your dive, as measured by the watch.
See COMPARTMENT NITROGEN LOADING GRAPH.
Using the Diving Mode
Make sure you are out of the water whenever performing button operations
before or after diving.

watchs surface timer starts to count the

surface interval is counted up to 48 hours or
until you begin your next dive.

In the Timekeeping Mode (after exiting the
Diving Mode following a valid dive), press D
to display the Surface Interval screen.
To return to the Timekeeping screen, press

Using the Watch while Skin Diving
You can use this watch while skin diving without affecting dive data or surface
interval timing. Log data is not stored in memory and surface interval timing
continues as long as you do not start a valid dive.
Log Memory
After finishing a dive, log data for the dive is stored into the watchs Log
Memory when you exit the Diving Mode and enter the Timekeeping Mode.
The watch has enough memory to store up to 20 log data records. The
following are the items stored for each log data record.
When the Surface Interval time reaches 48 hours, the displayed time
changes automatically of
xx:xx.
Up to 20 log data records can be stored in memory. Once memory is full,
memory is updated by storing the newest record and deleting the oldest
record.
In addition to the log data listed above, the watch also stores depth data in
memory. See DIVE PROFILE for more information.

To enter the Diving Mode before diving
In any other mode, hold down C for about two
seconds to enter the Diving Mode.
While the watch is in the Diving Mode, it will
automatically start measurements whenever
you are submerged and stop measurements
whenever you are on the surface.
To exit the Diving Mode after diving
After finishing your diving, hold down C for about two seconds to exit the
Diving Mode and enter the Timekeeping Mode.
Note that you cannot exit the Diving Mode while you are submerged.
Note
If you switch to the Timekeeping Mode after surfacing, be sure to switch
back to the Diving Mode before starting your next dive. If you stay in the
Diving Mode after surfacing, your next dive will be considered a
continuation of the previous dive, with data being added on accordingly.
Exiting the Diving Mode after a valid dive causes information about the
dive to be recorded in the watchs Log Memory.
If you leave the watch with the Diving Mode Surface Screen on the display
without performing a button operation for about one hour after surfacing, it
automatically exits the Diving Mode and enters the Timekeeping Mode.
Always check to make sure the watch is actually in the Diving Mode before
actually starting a dive.
Dive times can be measured up to 11 hours 59 minutes and 59 seconds.
When the dive time reaches 12 hours, the watch automatically stores log
data up to that point and exits the Diving Mode and enters the Timekeeping
Mode. The watch also starts measuring the surface interval at this time.

1. Use C to enter the Recall Mode.
The initial screen that appears is the data screen for the last (newest)

Each press of A toggles between the date screen and maximum depth
screen.
Pressing B and D at the same time displays the date screen for the last
recorded log data.
Note
The watch comes with sample data for a single dive in its Log Memory for
demonstration purposes.
The Maximum Depth screen alternates every five seconds between display
of the maximum depth and average depth.
The Unused Record screen shows the number of records in memory that
do not contain any data. It is located after the oldest record currently stored
in memory.
