Auto Return Feature
• After you perform an operation in any mode (except for the backlight
operation), pressing M returns to the Timekeeping Mode.
• If you leave a screen with flashing digits or cursor on the display for two
or three minutes without performing any operation, the watch automatically
saves anything you have input up to that point and exits the setting screen.
• If you leave the watch in Site and Identification Modes for about one
hour without performing any operation, it automatically changes to the
Timekeeping Mode.
Data and Setting Scrolling
The B and C buttons are used in various modes and screens to scroll
through data on the display. In most cases, holding down these buttons
during a scroll operation scrolls through the data at high speed.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping
Mode is also applied in the Dive Time Measurement, Site, and Alarm Modes.
• With the 12-hour format, the P (PM) indicator appears to the left of the
hour digits for times in the range of noon to 11:59 pm. No indicator is
shown from midnight to 11:59 am.
• With the 24-hour format, times are indicated in the range of 00:00 to
23:59, with 24 indicator.
Timekeeping Mode Notes
• The day of the week is automatically displayed in accordance with the
year, month, and day settings.
• The year can be set in the range of 1995 to 2039.
• The watch’s built-in full automatic calendar automatically makes
allowances for different month lengths and leap years. Once you set the
date, there should be no reason to change it except after the replacement
of the watch’s battery.
Site Mode
• The current time in all Site Mode sites is calculated in accordance with
the Greenwich Mean Time (GMT) differential for each site, based on the
current Home Site time setting in the Timekeeping Mode.
• The GMT differential is the time difference of the time zone where the
site is located from Greenwich Mean Time.
• The seconds count of the Site Time is synchronized with the seconds
count of the Timekeeping Mode.
• GMT differential is calculated by this watch based on Universal Time
Coordinated (UTC) data.
Backlight Precautions
• The electro-luminescent (EL) panel loses illuminating power after very
long use.
• The illumination provided by the backlight may be hard to see when
viewed under direct sunlight.
• The watch will emit an audible sound whenever the display is illuminated.
It does not indicate malfunction of the watch.
• The backlight automatically turns off whenever an alarm sounds.
Auto light switch precautions
• Avoid wearing the watch on the inside of your wrist. Doing so causes the
auto light switch to operate when it is not needed, which shortens battery
life.
• The backlight turns off in about two seconds, even if you keep the watch
pointed towards your face.
• The backlight may not light if the face of the watch is more than 15 degrees
off the parallel as shown below. Make sure that the back of your hand is
parallel to the ground.
• Static electricity or magnetic force can interfere with proper operation of
the auto light switch. If the backlight does not light, try moving the watch
back to the starting position (parallel with the ground) and then tilt it back
toward you again. If this does not work, drop your arm all the way down
so it hangs at your side, and then bring it back up again.
• Under certain conditions the backlight may not light until about one second
after you turn the face of the watch towards you. This does not necessarily
indicate malfunction of the backlight.

About the Battery
Whenever battery power is below a certain level, the flashing indicator
appears, display characters appear dim, the backlight may fail to light, the
alarm may fail to sound and the auto light switch does not operate. For safety
reasons, the watch will not enter the Dive Time Measurement Mode when
battery power is low. This is indicated by the message BATT appearing
when you hold down M to enter the Dive Time Measurement Mode. Using
the watch while the battery is low can result in abnormal operation.
Even when battery power is not low, leaving the backlight on can cause
the flashing indicator to appear temporarily. In this case, the
indicator should disappear from the display after a while. However, note
that alarm and backlight functions, which are normally disabled when battery
power is low, are also disabled when the indicator is temporarily flashing
due to the condition described above. Normal watch operation will return
after the indicator disappears. If it doesn’t disappear, have the battery
replaced. The amount of time it takes for the low battery warning indicator
to disappear depends on operating conditions.
ALWAYS LEAVE BATTERY REPLACEMENT UP TO THE DEALER
WHERE YOU BOUGHT THE WATCH OR TO AN AUTHORIZED CASIO
DISTRIBUTOR. BE SURE TO SHOW THE FOLLOWING
INFORMATION TO THE PERSON REPLACING THE BATTERY.
Attention dealer or CASIO distributor
Be sure to use the following procedure when replacing the battery.
1. Open and remove the back cover.
• Opening the back cover causes the message OPEN to appear on the
display.
• If CLOSE appears on the display when you open the back cover,
replace the back cover. Wait for a few minutes and try again.
2. Remove the battery holder.
3. Remove the old battery and load a new one.
4. Replace the battery holder.
5. Touch the AC contact and the battery (+) side with metallic tweezers.
6. Close the back cover.
• The message WAIT appears on the display about 20 seconds after
you perform the AC (all clear) operation in step 5 of the above
procedure, indicating that the watch is performing an internal self-
check for data errors. Note that the OPEN message remains on the
display during the internal self-check procedure, even after you close
the back cover.
