While Skin Diving/Snorkeling
• Check to make sure that timer operation and depth measurement are
being properly.
• Take care when skin diving/snorkeling near rocks or coral to avoid
scratching the watch.
After Skin Diving/Snorkeling
• To avoid corrosion, rinse your watch thoroughly with fresh water to
remove salt water, dirt, etc. (When possible, soak the watch in fresh
water overnight to make sure that all salt is removed.)
• When using a metal band, occasionally clean inside the gaps in the
band using a soft toothbrush and soapy water. Failure to do so can
result in corrosion of the timepiece, soiling of clothing or irritation to
sensitive skin.
Depth Gauge Mode Precautions
• After you enter the Depth Gauge Mode, the watch automatically takes a
reference pressure reading and sets the result a 0 meters (feet). This
means that before starting a dive, you should enter the Depth Gauge Mode
while at the water's surface, never while the watch is submerged.
• A major change in air temperature or other phenomena while you are using
the Depth Gauge Mode can cause the display to show a value other than 0
meters (feet) when you are at the surface of the water. If this happens, reset
the reference depth to 0 meters (feet). See "To manually reset the reference
depth to 0 meters (feet)" for more information.
• Depth values are displayed in units of 0.1 meter (or 1 foot).
•
(or
0
)is displayed whenever your depth is less than one meter (four
feet).
•
dEEP
is displayed in place of the depth value whenever your depth is
greater than 30 meters (98 feet). If you continue to dive deeper after

will appear in place of the depth value. If
the display after you surface, hold down C for three seconds to exit the
Depth Gauge Mode. If
keeps appearing in place of the depth value, it
xxxx
could mean that the sensor is malfunctioning. Take the watch to the place
where you purchased it or to some other CASIO retailer to have it checked.
• If the elapsed measurement time exceeds three hours, the watch will
automatically switch to the Timekeeping Mode and store the data for the
current dive into log memory.
• The progress beeper and auto-repeat timer alarm do not sound while the
watch is in the Depth Gauge Mode.
• The watch can take about five minutes to display the correct water
temperature when there is a great difference between air temperature and
water temperature, when there is a sudden change in water temperature,
etc.
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. While in the Timekeeping Mode, press C to enter the Depth Gauge Mode.
2. Press B to cycle through the data screens in the sequence shown below.

Countdown Timer
You can set a countdown timer start time in the
1/10 second
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

Configuring the Countdown Timer
The following are the settings you should configure before actually using the
countdown timer.
• Countdown start time
• Auto-repeat on/off
• Progress beeper on/off
Countdown start time
You can set a countdown start time from 1 minute to 24 hours.
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,
and 1 of the final minute of the countdown.
To set the countdown start time and auto-repeat on/off
1. In the Countdown Timer Mode, hold down A
until the hour setting of the countdown start
time starts to flash, which indicates the setting
screen.
2. Press C to move the flashing in the sequence
shown below to select other settings.

3. Perform the following operations, depending
on which setting is currently selected on the
display.
• While the hour or minute setting is flashing,
use D (+) or B (–) to change it.
Auto-repeat indicator
• For a 24-hour countdown, set a start time of
0:00
• While the auto-repeat setting (ON or OFF) is flashing on the display,
press D to toggle auto-repeat on (ON) and off (OFF).
4. Press A to exit the setting screen.
• The auto-repeat indicator (
