Power Levels
Congratulations upon your selection of this CASIO watch.
You can get an idea of the watch’s power level by
observing the movement of the xSecond Hand in the
Timekeeping Mode.
• If the xSecond Hand is moving normally at one-second
intervals, power is at Level 1.
• If the xSecond Hand is moving at two-second intervals,
power is at Level 2, which is quite low. Expose the watch
to light as soon as possible so it can charge.

• When power drops to Level 3, all functions will be disabled but the watch will
continue to keep time internally for about one week. If you recharge the battery
sufficiently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
This User’s Guide uses numbers shown above to identify
watch hands and indicators.
Power Recovery Mode
Things to check before using the watch
The watch is designed to go into a power recovery mode that stops hand operation
temporarily whenever power suddenly drops below a certain level due to overuse
of the alarm tone over a short period. Note that all operations are disabled while the
watch is in the power recovery mode.
1. Hold down C for about two seconds to enter the Timekeeping Mode, and
then observe the movement of the xSecond Hand.
The hands will move to the correct positions and the watch will resume normal
operation after power recovers (in about 15 minutes). Putting the watch in a location
where it is exposed to light will help power to recover sooner.
Is the xSecond Hand moving smoothly at one-second intervals?
NO
YES
The watch is charged sufficiently.
For details about charging, see
“Charging the Watch”.
Is the xSecond Hand moving at
two-second intervals or is it stopped
completely?

See “Configuring Current Time and Date Settings”.
Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a
certain period in an area where it is dark. The table below shows how watch functions
are affected by Power Saving.
The watch is now ready for use.
• There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Charging the Watch
Elapsed Time in Dark
Operation
The face of the watch is a solar cell that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.
60 to 70 minutes (second hand
sleep)
xSecond Hand only is stopped at 12 o’clock, all other
functions are enabled.
• All functions, including analog timekeeping, disabled
• Internal timekeeping maintained.
6 or 7 days (function sleep)
Charging Guide
• The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch
is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep
state.
Whenever you are not
wearing the watch, be sure
to leave it in a location
where it is exposed to light.
• Best charging
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch,
makes sure that its face is
not blocked from light by the
sleeve of your clothing.
• The watch may enter a
sleep state if its face is
blocked by your sleeve
even only partially.
• The watch will not enter a sleep state while it is in the Stopwatch Mode.
To recover from the sleep state
Move the watch to a well-lit area or press any button.
Mode Reference Guide
Your watch has four “modes”. The mode you should select depends on what you
want to do.
Warning!
Leaving the watch in bright light for charging 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
To do this:
Enter this mode:
• View the current time in your Home City and in one of 29
cities around the globe
• Too close to an incandescent lamp
• Under direct sunlight
• Configure Home City and daylight saving time (DST)

Alarm Mode
• Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to ensure that power does not run down.
• 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 power to run down.
Make sure that the watch is exposed to bright light whenever possible.

• 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 rechargeable battery replaced or after
power drops to Level 3.
• Note that the STD (standard time)/DST (daylight
saving time) setting affects only the currently selected
time zone. Other time zones are not affected.
Using the Stopwatch
Swapping your Home City and World Time City
You can use the procedure below to swap your Home City and World Time City. This
capability can come in handy when you frequently travel between two locations in
different time zones.
The following example shows what happens when the Home City and World Time
City are swapped while the Home City originally is TOKYO (TYO) and the World Time
City is NEW YORK (NYC).
The stopwatch measures elapsed time and split times.

• If the stopwatch was not reset after the last elapsed time operation, timing will
restart from where it was last stopped, and not from 0.
• The xSecond Hand indicates the 1/10-second count for the first 30 seconds
of a stopwatch elapsed time operation. After that, the hand stops at 12 o’clock
position. 1/10-second timing continues internally after the first 30 seconds, and the
xSecond Hand will jump to the current value whenever B (Stop) or D (Split) is
pressed.
• Though the nRight Dial Hand is stopped while an elapsed time measurement
operation is in progress, the watch keeps track of the 1/100-second count
internally. The nRight Dial Hand will jump to the current 1/100-second reading
whenever you stop the stopwatch or perform a split time operation.
