Configuring The Countdown Timer - Casio 3047 Operation Manual

Depth Gauge Mode Precautions
• After you enter the Depth Gauge Mode, the watch takes a reference
pressure reading automatically 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 reset the reference depth to
0 meters (feet) manually" for more information.
• Depth values are displayed in units of 0.1 meter (or 1 foot).
•
(or ) appears on the display whenever your depth is less than one
0
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
appears, . will appear in place of the depth value. If

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 switch
to the Timekeeping Mode automatically 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.
To take a direction reading in the Depth Gauge Mode
• • • • • Never operate the buttons of the watch while underwater.
1. In the Depth Gauge Mode, place the watch on
12 o'clock position
a flat surface, or if you are wearing the watch,
Timekeeping
Mode Time make sure that your wrist is horizontal (in
relation to the horizon).
2. Point the 12 o'clock position of the watch in
the direction you want to read.
3. While the elapsed measurement time/current
depth screen is displayed, press A to start
direction reading operation.
• After about two seconds, the direction that the

• About five or six seconds after you display the
Digital Compass screen, the watch will return
to the Depth Gauge screen automatically.
• The watch will also return to the Depth Gauge
screen if you press A again.
Depth Data Recall Mode
You can use the Depth Data Recall Mode to view log data that was recorded
in the Depth Gauge Mode. There is enough memory to store up to 40 log
entries, plus one maximum depth record. Each log entry 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.
Dive Date (Month – Day)
Water temperature at maximum depth: This value shows the water
temperature at the maximum depth attained during the dive.
The following information is stored in the maximum depth record when a new
maximum is attained.
Total Time Submerged
Maximum depth value: Maximum depth value in memory
Dive Date (Month – Day)
Water temperature at maximum depth
• If the depth that is attained is the same as the current maximum depth
value, the older data takes priority and the maximum depth record is not
updated.
• The maximum depth record is not cleared even if you delete the 40 log data
entries.
• Perform the following steps to view the log data that is currently stored in
memory.

Countdown Timer
You can set a countdown timer start time in the
Timekeeping Mode Time
range of one minute to 60 minutes. 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
countdown timer.
• Countdown start time and reset time
• Auto-repeat on/off
• Progress beeper on/off
Countdown start time
You can set a countdown start time from one minute to 60 minutes.
Auto-repeat
Whenever zero is reached, the watch beeps (auto-repeat timer alarm) and
auto-repeat restarts the countdown automatically 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. Auto-repeat will repeat up to 10 times.
Progress Beeper
The progress beeper actually includes two beepers: a reset time beeper and
a reset period progress beeper.
• The reset time beeper and reset period progress beeper sound only while
the progress beeper is turned on.
Reset Time Beeper
The reset time beeper is similar to the countdown end beeper. When the
progress beeper is turned on, the watch beeps each second of the final 10
seconds before the countdown reaches the reset time.
