Viewing Recorded Data
You can use the Data Recall Mode to view data that was recorded in the Timekeeping Mode or the sensor
modes. You can also view Depth Meter auto recorded data.
• See the following sections for more information: Recording the Date and Time (page E-38), Recording
Barometric Pressure (page E-52), Recording the Bearing to an Objective (page E-64), Recording Altitude
(page E-70), Recording Temperature (page E-80), Recording Depth and Dive Time (page E-83)
To display a data record
1. In the Timekeeping Mode, press
B
.
•
This will enter the Data Recall Mode.
• RECALL a
ppears on the display for one second, followed by data record that was displayed when
the Data Recall Mode was last exited.
2. Use
A
to select the record you want.
• Records are displayed in the chronological order they were recorded.
• Manually saved records are assigned numbers in the sequence they are recorded. If you create a
n
e
w data record (by saving data) while there are already 40 records in memory, record number 01
(the oldest) will be deleted automatically to make room for the new one. The numbers of the other
records will also be shifted accordingly.
• Holding down
A
sc
rolls records at high speed.
E-86
• Even if an error occurs, dive time measurement will continue if it is
already started.
• Hold down
B
for about three seconds to enter the Timekeeping Mode.
• Recovering from an error displays the measurement value, but a
fl
ashing warning mark (
!
) will also be displayed.
If a sensor error occurs, do not use the watch for diving and contact an authorized CASIO service
center as soon as possible for repair.
Troubleshooting when a Flashing Warning Mark ( ! ) Appears
A fl ashing warning mark (
!
) in the Depth Meter Mode means some problem occurred during a
measurement, or that there was some operation error. The warning mark also will appear (without
fl ashing) whenever the log data that was recording during the measurement problem or operation error is
displayed. Log data for which the warning mark appears should not be used, because it contains large
error.

Water depth sensor error
E-85
Negative water depth error
The conditions described below may result in impossible depth readings
(–1.0 meter or less).
• Using the watch where abnormal barometric pressure changes occur.
• Entering the Depth Meter Mode while in the water and then surfacing
or exiting the water after a dive.
Such conditions will cause a negative depth reading error and cause the warning mark (
!
) to fl
ash on the
display. Almost all negative depth errors occur on the water surface. To clear a negative depth error,
switch momentarily from the Depth Meter Mode to another mode (Timekeeping Mode, etc.) A fl ashing
warning mark (
!
) indicates that a negative error has occurred, and that there will be large error in
displayed data.
• A negative depth error does not indicate malfunction of the watch. The watch will operated normally
after the error is cleared. However, any data that was measured prior to the depth error will have large
error. Returning to the Timekeeping Mode and entering the Depth Meter Mode again to re-start new
measurement is recommended.
• Normal data measurement and log data auto recording will be performed after a negative depth error
screen appears, but the warning mark (
!
) will continue to fl
ash.
Sensor error
A sensor error occurs, indicated by display of
ERR
if strong impact or other force damages a sensor,
causes faulty sensor connection, etc.

Important!
• The watch has memory for storage of up to 40 records of various types besides depth records. Note
th
at recording new data when there are 40 records in memory causes the oldest record to be deleted
automatically to make room for the new record. See “Viewing Recorded Data” (page E-87).
To record depth manually
In the Depth Meter Mode, hold down
A
for at least two seconds.
• This records the depth along with the current date and time.
Measurement Error Troubleshooting
Dive measurement start error
If you start a dive without entering the Depth Meter Mode and then enter
the Depth Meter Mode at a depth greater than 1.5 meters, the current
depth will be displayed using the standard atmosphere 1,013 hPa as the
0-meter depth.
• Since the water surface is not measured as 0 meters, there is large
error between the measured depth and the actual depth.
• At this time, a warning mark (
!
) will fl
ash on the display to warn you.
• In this case, measurement starts at a depth of 1.5 meters or greater, so
the displayed dive time will be shorter than the actual dive time.
Water Depth Measurement Precautions
Underwater pressure increases along with the depth. In the case of seawater (Specifi
c Gravity: 1.025),
water pressure increases one atmosphere (1.03kg/cm
2
) with each 10-meter increase in depth. The water
depth sensor of your watch detects water pressure, and the watch uses the relationship between water
pressure and depth to display a seawater depth value.

• Holding down
B
for two seconds while dive time measurement is in progress will return to the
Timekeeping Mode, but measurement values will not be stored in memory at that time.
• If you do not perform any operation for about 60 minutes, the watch will record the depth at that point
and return to the Timekeeping Mode.
Taking direction and Temperature Readings while Diving
While depth/diving time measurement is in progress, press
A
to cycle through the sensor modes until the
Digital Compass Mode or Temperature Mode screen appears. See “Selecting a Mode” (page E-30).
• Depth/diving time measurement continues to be performed even while the Digital Compass Mode or
Temperature Mode screen is displayed.
• This watch will automatically return to the Depth Meter Mode screen if you do not perform any operation
for about 10 seconds while the Digital Compass Mode or Temperature Mode screen is displayed.
Important!
• The watch will take approximately fi ve minutes to become acclimatized to sudden temperature
changes (difference between air temperature and water temperature, change in the water temperature,
etc.) and display the actual water temperature.
Recording Depth and Dive Time
There are two types of recorded Depth Meter Mode data: auto recorded data and manually recorded data.
Auto recorded data includes maximum depth and dive time, along with the current date and time. Manually
recorded data includes depth, along with the current date and time. Recorded data can be recalled for
viewing as required.
E-82
• When you start your dive and reach a depth of 1 meter, the watch will automatically start depth and
dive time measurement.
Water depth
Dive time
C
• If you ascend to a depth of 1 meter or less, the watch will create a record of your maximum depth and
dive time, along with the current date and time, and stop dive time measurement.
– An auto measurement result is displayed for two to three minutes.
Maximum depth Dive Time
– Pressing
A
or
C
returns to the normal depth measurement value.
– While the result is displayed, submerging to a depth greater than one meter will re-start auto
measurement.
• Pressing
B
while dive time measurement is in progress will not change to another mode. Perform the
button operation after measurement is ended.
E-81
Using the Depth Meter Mode
You can use the Depth Meter Mode to measure water depth and dive time, and automatically store
measurements in memory. You can also take direction and temperature readings while measuring depth
and dive time.
Important!
• Before diving, enter the Depth Meter Mode while on a boat or in another location outside the water.
• Displayed measurement values are approximate and are intended for general reference only. The
Depth Meter Mode of this watch is intended for use while free diving, snorkeling, etc.
Note
• In the Depth Meter Mode, the second hand indicates water depth.
• In the Depth Meter Mode, Auto Light is disabled.
Measurement Data and Ranges
Water Depth Measurement Measurement unit: 0.1 meter
Measuring range: 0 to 50 meters*
Dive Time Measurement unit: 1 second
Measurement range: 59 minutes, 59 seconds
* A measurement outside the allowable range is displayed as

.
Measuring Water Depth and Dive Time
While in the Timekeeping Mode or a sensor mode, use
A
to cycle through the sensor modes until
DEPTH
appears on the display. See “Selecting a Mode” (page E-30).
• This enters the Depth Meter Mode and starts depth measurement.
E-80
Recording Temperature
You can use the procedure in this section to create a record of the current temperature, along with the
date and time of the reading. You can later recall a record to view it.
Important!
• The watch has memory that is shared for storage of up to 40 records, including temperature records.
Note that recording new data when there are 40 data records in memory causes the oldest record to
be deleted automatically to make room for the new record. See “Viewing Recorded Data” (page E-87).
To record the temperature
While taking temperature readings, hold down
A
for at least two seconds.
• This records the temperature along with the current date and time.
• The watch will return to the Temperature Mode screen automatically after recording is complete.
Thermometer Precautions
• Temperature readings are affected by your body temperature, direct sunlight, and moisture. To achieve
a more accurate temperature reading, remove the watch from your wrist, place it in a well ventilated
location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30
minutes for the case of the watch to reach the surrounding temperature.
