TIMEKEEPING  
WORLD TIME  
Use the Timekeeping Mode to set and view  
the current time and date.  
The World Time Mode shows you the current  
time in 27 cities (29 time zones) around the  
world.  
For full information on city codes, see the  
CITY CODE TABLEat the back of this  
manual.  
The time settings of the Timekeeping Mode  
and the World Time Mode are independent  
from each other, so you must make  
separate settings for each.  
Whenever you change the time setting for  
any city in the World Time Mode, the settings  
of all other cities are changed accordingly.  
World Time functions are available in the  
World Time Mode, which you can enter

When the end of the countdown is reached while auto repeat is on, the  
alarm sounds, but the countdown starts again automatically whenever  
the countdown reaches zero. You can stop timing by pressing B, and  
manually reset to the starting countdown time by pressing D.  
Normally, an alarm tone sounds for about 10 seconds when the end of  
the countdown is reached. If you use auto repeat with start time of 10  
seconds or less, the alarm tone sounds for only one second.  
Frequent use of auto repeat with a short countdown time can reduce  
the charge of the storage battery and cause the countdown time alarm  
to become disabled, so it does not sound.

About Auto-Start  
With Auto-Start, the watch performs a 5-second countdown, and  
stopwatch operation starts automatically when the countdown reaches  
zero.  
During the final three seconds of the countdown, a beeper sounds with  
each second.  
BACKLIGHT  
The backlight uses an EL (electro-  
luminescent) panel that causes the entire  
display to glow for easy reading in the dark.  
The watchs auto light switch automatically  
turns on the backlight when you angle the  
watch towards your face.  
The auto light switch must be turned on  
(indicated by the auto light switch on  
indicator) for it to operate.  
To use Auto-Start  
1. While the stopwatch screen is showing all  
zeros in the Stopwatch Mode, press A.  
This displays a 5-second countdown  
screen.  
To return to the all zeros screen, press  
A again.

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on  
whenever you position your wrist as described below in any mode. Note  
that this watch features a Full Auto EL Light,so the auto light switch  
operates only when available light is below a certain level. It does not  
turn on the backlight under bright light.

Alarms, Hourly Time Signal, backlight,  
display, timekeeping disabled.  
Moving the watch to a position that is parallel to the ground and then  
tilting it towards you more than 40 degrees causes the backlight to  
turn on.  
At Level 4, the display is disabled but timekeeping and other functions  
continue to operate internally. Pressing any button causes the  
Timekeeping Mode screen to appear for two or three minutes.  
At Level 5, all functions are disabled. Functions are enabled once again  
after the storage battery is charged, but anything previously stored in  
memory is lost. Because of this, you must set the current time and alarms,  
and re-input Data Bank records after the storage battery is charged.  
Leaving the watch in direct sunlight or some other very strong light  
source can cause the battery power indicator to temporarily show a  
reading that is actually higher than the battery level. The correct  
battery power indicator should appear after a few minutes.  
Frequent backlight and alarm operations over a short period put a  
heavy load on the battery, which can cause the battery power indicator  
to flash, indicating that the backlight and alarm are disabled. Normal  
operations should return after the battery recovers from the overload  
condition. The above condition can occur after about consecutive 200  
backlight operations or about 360 alarm operations.

Warning!  
Always make sure you are in a safe place whenever you are  
reading the display of the watch using the auto light switch. Be  
especially careful when running, riding a bicycle or motorcycle,  
driving a car, or engaged in any other activity that can result in  
accident or injury. Also take care that sudden illumination by the  
auto light switch does not surprise or distract others around you.

modes while the auto light switch is turned on.  
Frequent use of the auto light switch greatly reduces the charge of the  
storage battery. If you use the auto light switch often, be sure to leave  
the watch where it is exposed to sunlight during the daytime so it can  
recharge the storage battery. 10 minutes exposure to sunlight provides  
enough of a charge for about 10 to 20 auto light switch operations.  
Warning!  
Leaving the watch in sunlight to charge its storage battery can  
cause it to become quite hot. Take care when handling the watch to  
avoid burn injury.

Important!  
Storing the watch for long periods in an area where there is no light or  
wearing it in such a way that it is blocked from exposure to light can  
cause storage battery power to run down. Be sure that the watch is  
normally exposed to light whenever possible.  
To enter the Sleep Mode  
In any mode (except while figures are flashing  
on the display for input), hold down C for  
about two seconds.  
Sleep Mode indicator  
This watch employs a solar cell that converts light into electricity that  
charges a built-in storage battery. Normally, the storage battery should  
not need replacement, but after very long use over a number of years,  
the storage battery may lose its ability to achieve a full charge. Should  
you notice problems with getting the storage battery to a full charge,  
contact your dealer or CASIO distributor about having the storage  
battery replaced.  
The storage battery should be replaced with a CASIO-specified ML-2016  
battery only. Other storage batteries can cause damage to the watch.  
Be sure to put the watch into its Sleep Mode and keep in an area  
normally exposed to light when storing it for long periods. This helps to  
keep the storage battery from going dead.  
This enters the Sleep Mode, which causes  
all figures (except Sleep Mode indicator) to  
disappear from the display. Timekeeping  
and other functions continue to be  
performed internally, however.  
Alarms, the Hourly Time Signal, and the  
backlight are disabled while the watch is in  
the Sleep Mode.

watch is more than 15 degrees above or  
below parallel. Make sure that the back of  
your hand is parallel to the ground.  
The backlight turns off in about two  
seconds, even if you keep the watch  
pointed towards your face.  
Auto Display is a demonstration feature that continually changes the  
contents of the digital display. Note that you cannot use any of the  
watchs other functions while Auto Display is operating.  
To turn off Auto Display  
Hold down A for about two seconds until the watch beeps.  
To turn on Auto Display  
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.  
1. In any mode (except while figures are flashing on the display for  
input), hold down C for about two seconds to enter the Sleep Mode.  
2. Hold down A for about two seconds until the watch beeps. This  
indicates that Auto Display is on.  
Leaving the watch in a dark area can cause Auto Display operation  
to stop. Normal operation should resume when the watch is again  
exposed to light.  
Auto Display cannot be turned on while the storage battery is at  
Level 4 or Level 5. Auto Display also turns off automatically  
whenever the storage battery drops to Level 4 or Level 5.

Backlight Precautions  
The electro-luminescent panel that provides illumination loses power  
after very long use.  
The illumination provided by the backlight may be hard to see when  
viewed under direct sunlight.  
The watch may emit an audible sound whenever the display is  
illuminated. This is due to vibration of the EL panel used for  
illumination, and does not indicate malfunction.  
The backlight automatically turns off whenever an alarm sounds.  
The backlight remains lit for about two seconds from the point you  
press the button, even if it is already lit when you press the button. If  
you keep the button depressed for two seconds or more, the backlight  
automatically turns off.

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. If you want to wear the watch on the inside of your wrist,  
turn off the auto light switch feature.
