CDT (Countdown Timer) SETUP
This screen allows you to program a countdown timer with audible alarm. Choose ON, OFF, or SET. To set the
timer you must save an hour value then the minute value. You may choose a value between 0:01 and 23:59.
Once the CDT is set to ON, it may be started and paused in the ALT 2 screen. Selecting ON does not start the
CDT; it must be activated in the Watch ALT 2 screen. See Alt 2 section in this chapter for further details.

CHRONO (CHRONOGRAPH)
The chronograph has a 9 lap memory. After 9, subsequent laps will be recorded and the earliest lap discarded.
If the Chrono continues to run and reaches 9:59:59.99, it will stop and record that as a Lap. Subsequent presses
of SELECT then have no effect.
NOTE: If the Chrono continues to run and reaches 9:59:59.99, it will stop and record that as a Lap.
Subsequent presses of SELECT then have no effect.
NOTE: Once the Chrono has been set and started, it will remain on and displayed (or continue to run
in the background) while on the surface until reset by the user. Upon descending to 5 FT/1.5 M (i.e.,
entry into a Dive, Gauge, or Free Mode dive), operation will be terminated and the counter will reset to
0:00:00.00 (hr:min:sec.centisecond).
