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.

• 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.

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.

Function Status
• At Level 5, all functions are disabled and settings return to their initial factory

current time, date, and other settings.
Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.

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
to become quite hot.Take care when handling the watch to avoid burn injury.
The watch can become particularly hot when exposed to the following
conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight

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.

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.

Illumination Precautions
When you enter the World Time Mode or Alarm Mode, the data you were viewing
