Log Data
Exiting the Depth Gauge Mode after a dive causes the measured data to be
stored automatically into log memory. Stored data remains in log memory
until you start a new dive, which causes the existing data to be replaced with
the data of the new dive.
There is memory for a single log memory record, which includes the following
data.
Total Time Submerged: This value shows the cumulative amount of time
(hours, minutes, seconds) that you spend submerged at a depth of
one meter (four feet) or greater.
Maximum depth: This value shows the maximum depth you attained during
the dive.
Water temperature at maximum depth: This value shows the water
temperature at the maximum depth attained during the dive.
Perform the following steps to view the log data that is currently stored in
memory.
To view log data
1. Enter the Depth Gauge Mode.
2. While
(or
0
) is shown on the display, press
C
to cycle through the data
screens in the sequence shown below.

Countdown Timer
You can set a countdown timer start time in the
range of 1 minute to 24 hours. An alarm sounds
when the countdown reaches zero. An auto-
repeat feature causes the countdown to restart
automatically when the end of a countdown is
reached, and a progress beeper signals the
progress of the countdown. All of this makes the
countdown timer a valuable tool for timing the
start of a yacht race.
•
All of the operations in this section are
performed in the Countdown Timer Mode,
which you enter by pressing
D
.
Configuring the Countdown Timer
The following are the settings you should configure before actually using the

Auto-repeat
Whenever zero is reached, the watch beeps (Auto-repeat timer alarm) and
auto-repeat automatically restarts the countdown from the countdown start
time you set. Turning off auto-repeat causes the countdown to stop and the
countdown start time to appear on the display when the end of the countdown
is reached.
Progress Beeper
When the progress beeper is turned on, the watch beeps at minute 10, 5, 4,
3, 2, and 1, of the countdown, and at the second 50, 40, 30, 20, 10, 5, 4, 3, 2,
