Getting Acquainted  
Congratulations upon your selection of this CASIO watch. To get the most out of your  
purchase, be sure to read this manual carefully.  
Keep the watch exposed to bright light  
The electricity generated by the solar cell of the watch is  
Bright Light  
stored by a built-in battery. Leaving or using the watch  
where it is not exposed to light causes the battery to run  
down. Make sure the watch is exposed to light as much as  
possible.

l
Solar cell  
When you are not wearing the watch on your wrist,  
position the face so it is pointed at a source of bright  
light.  
You should try to keep the watch outside of your sleeve  
as much as possible. Charging is reduced significantly if  
the face is only partially covered.  
E-1  
The watch continues to operate, even when it is not exposed to light. Leaving the  
watch in the dark can cause the battery to run down, which will result in some watch  
functions being disabled. If the battery goes dead, you will have to re-configure  
watch settings after recharging. To ensure normal watch operation, be sure to keep it  
exposed to light as much as possible.  
The actual level at which some functions are disabled depends on the watch model.  
Be sure to read “Power Supply” (page E-33) for important information you  
need to know when exposing the watch to bright light.  
If the display of the watch is blank...  
If the display of the watch is blank, it means that the watch’s Power Saving function  
has turned off the display to conserve power.

To configure the countdown timer  
Dual timers can be set with two different starting times. The watch can be configured  
so the two timers alternate, so when one reaches the end of its countdown, the other  
timer starts.You can specify a “number of repeats” value from 1 (once) to 10 (ten  
times), which controls how many times the two-timer countdown operation is  
performed. The starting time of each timer can be set in five-second steps up to 99  
minutes, 55 seconds.  
1. While the countdown start time is on the display in the  
Countdown Timer Mode, hold down A until the current  
countdown start time starts to flash, which indicates the

(approximately 1.5 seconds) and LT3 (approximately 3  
seconds).  
Example: Orient the watch so its face is

The illustration shows how to position a  
watch with a resin band.  
4. Press A to exit the setting screen.  
Note that charging efficiency drops when  
any part of the solar cell is blocked by  
clothing, etc.  
You should try to keep the watch outside of  
your sleeve as much as possible. Charging  
is reduced significantly if the face is  
covered only partially.  
E-32  
E-33  
Important!  
To check the current battery level  
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 rechargeable battery  
power to run down. Be sure that the watch is exposed to bright light whenever  
possible.  
When the battery level is at Level 1 (HI) or Level 2 (MID), the corresponding battery  
level indicator (HI or MID, page E-8) will appear only if you press C in the  
Timekeeping Mode. For other battery levels, the applicable indicator appears  
automatically.  
This watch uses a rechargeable battery to store power produced by the solar cell, so  
regular battery replacement is not required. However, after very long use, the  
rechargeable battery may lose its ability to achieve a full charge. If you experience  
problems getting the rechargeable battery to charge fully, contact your dealer or  
CASIO distributor about having it replaced.  
Battery level indicator  
Never try to remove or replace the watch’s rechargeable battery yourself. Use of the  
wrong type of battery can damage the watch.  
The current time and all other settings return to their initial factory defaults whenever  
battery power drops to Level 5 (pages E-36 and E-37) and when you have the  
battery replaced.  
Turn on the watch’s Power Saving function (page E-46) and keep it in an area  
normally exposed to bright light when storing it for long periods. This helps to keep  
the rechargeable battery from going dead.

Level Battery Level Indicator  
Function Status  
At Level 5, all functions are disabled and settings return to their initial factory  
defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the  
current time, date, and other settings.  
Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.

Leaving the watch exposed to direct sunlight or some other very strong light source

Certain charging conditions can cause the watch to become very hot. Avoid leaving  
the watch in the areas described below whenever charging its rechargeable battery.  
Also note that allowing the watch to become very hot can cause its liquid crystal  
display to black out. The appearance of the LCD should become normal again when  
the watch returns to a lower temperature.  
After some time, battery power will recover and

Warning!  
Leaving the watch in bright light to charge its rechargeable battery can cause it

The hour and minute hands should move to 12 o’clock  
(their home position), and “0:00” will flash on the  
display.  
If the hour and minute hands are not at 12 o’clock,  
use D (+) and B (–) to move them there.  
Holding down either button will cause the hands to  
move at high speed. Once started, high-speed hand  
movement will continue even if you release the button.  
To stop high-speed hand movement, press any button.  
High-speed hand movement started with the D (+)  
button will stop automatically after 12 revolutions of  
the minute hand. If started with the B (–) button, it  
will stop after one revolution of the minute hand.  
Adjusting Home Positions  
Strong magnetism or impact can cause the hands of the watch to be off. If this  
happens, perform the applicable home position adjustment procedures in this section.  
Hand home position adjustment is not required if the analog time and digital time are  
the same in the Timekeeping Mode.  
To adjust home positions  
1. In the Timekeeping Mode, hold down A for about five seconds.You can release the  
button after “H.SET” appears on the display.  
Though “ADJ” will appear on the display after about two seconds, do not release  
the button yet. Keep it depressed until “H.SET” appears.  
Correct hour and  
minute hand positions  
2. After everything is the way you want, press A to return to the Timekeeping Mode.  
After performing home position adjustment, enter the Timekeeping Mode and check  
to make sure that the analog hands and the digital display indicate the same time. If  
they do not, perform home position adjustment again.

The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch  
is already in the sleep state when 6:00 AM arrives, however, it will remain in the  
sleep state.  
To recover from the sleep state

Timekeeping  
Auto Return Features  
Resetting the seconds to 00 while the current count is in the range of 30 to 59  
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are  
reset to 00 without changing the minutes.  
If you leave the watch in the Alarm Mode, or with the battery level indicator displayed  
for two or three minutes without performing any operation, it automatically returns to  
the Timekeeping Mode.  
If you leave the watch with a flashing setting on the display for two or three minutes  
without performing any operation, the watch automatically exits the setting screen.  
The year can be set in the range of 2000 to 2099.  
The watch’s built-in full automatic calendar makes allowances for different month  
lengths and leap years. Once you set the date, there should be no reason to change  
it except after you have the watch’s battery replaced or when battery power drops to  
Level 5.  
The current time for all city codes in the Timekeeping Mode and World Time Mode is  
calculated in accordance with the Coordinated Universal Time (UTC) for each city,  
based on your Home City time setting.  
Scrolling  
The B and D buttons are used in various modes and setting 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.  
Initial Screens  
Illumination Precautions  
When you enter the World Time Mode or Alarm Mode, the data you were viewing  
when you last exited the mode appears first.  
Illumination may be hard to see when viewed under direct sunlight.  
Illumination automatically dims if it is lit and an alarm or time up alarm sounds.  
Frequent use of illumination runs down the battery.
