Operation Guide 5060
Congratulations upon your selection of this CASIO watch.
Power Levels
B
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 in one-second
steps, power is at Level 1.
+
This watch does not have a city code that corresponds to the UTC offset of –3.5
hours. Because of this, the radio-controlled atomic timekeeping function will not
display the correct time for Newfoundland, Canada.
• If the xSecond Hand is jumping at two-second steps,
power is at Level 2, which is quite low. Expose the watch
to light as soon as possible so it can charge.
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage
or loss suffered by you or any third party arising through the use of this product or
its malfunction.

• 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 normal 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.
Things to check before using the watch
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 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.
Is the xSecond Hand moving smoothly in one-second steps?
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.

• To set the time manually
See “Configuring Current Time and Date Settings Manually”.
Power Saving
The watch is now ready for use.
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.
• For details about the watch’s radio controlled timekeeping feature, see “Radio
Controlled Atomic Timekeeping”.
• There actually are two sleep state levels: “second hand sleep” and “function sleep”.

• All functions, including analog timekeeping, disabled
• Internal timekeeping maintained.
6 or 7 days (function sleep)
• 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.
• The watch will not enter a sleep state while it is in the Stopwatch Mode or
Countdown Timer Mode.
Charging Guide
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.
To recover from the sleep state
Move the watch to a well-lit area or press any button.
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
• Too close to an incandescent lamp
• Under direct sunlight
Important!
• 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.

To toggle the Home City time between standard time and daylight saving time
1. Perform the step 1 under “To configure Home City settings”.
To do this:
Enter this mode:
• Each time you select a city code, the zHour Hand, cMinute Hand, and
bLower Dial Hand move to the current time for that city code. Do not perform
the next operation until these hands stop moving.
• View the current date in the Home City
• Configure Home City and daylight saving time

Note
With this watch, everything starts from the Timekeeping Mode.
• After you specify a city code, the watch will use UTC* offsets in the World Time
Mode to calculate the current time for other time zones based on the current time
in your Home City.
To determine the watch’s current mode
Check the position of the vLeft Dial Hand as shown
under “To select a mode”.
* Coordinated Universal Time, the world-wide scientific standard of timekeeping.
The reference point for UTC is Greenwich, England.
• Selecting some city codes automatically makes it possible for the watch to
receive the time calibration signal for the corresponding area. See “Radio
Controlled Atomic Timekeeping” for details.
To return to the Timekeeping Mode from any other
mode
Hold down C for about two seconds until the watch beeps
twice.

Mode positions. Note, however, that 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.

a stopwatch elapsed time operation. After that, the hand stops at 0. 1/20-second
timing continues internally after the first 30 seconds, and the vLeft Dial Hand will
jump to the current value whenever B (Stop) or D (Split) is pressed.

To swap your Home City and World Time City
1. In the World Time Mode, use D to select the World
Time City you want.
• In this example, you would move the xSecond Hand
to NYC in order to select New York as the World
Time City.
• Wait until the nRight Dial Hands complete their
move to the time in the currently selected World Time
City. You will not be able to perform step 2 of this
procedure until the hands stop moving.
• Each press of C in the home position adjustment mode will cycle through the
adjustment settings as shown below.
3. After confirming that the xSecond Hand is at the proper home position, press C.
This will switch to zHour Hand and cMinute Hand home position adjustment.
• The zHour Hand and cMinute Hand are at their proper home positions if
they both move to 12 o’clock. The bLower Dial Hand also will move along with
zHour Hand movement, and cannot be adjusted individually. If the hands are
not positioned correctly, use D (+) and B (–) to move
B

them to their proper home positions.
4. After confirming that the zHour Hand and cMinute
Hand are in their correct home positions, press C.
This will switch to nRight Dial Hand home position
adjustment.
• The nRight Dial Hands are at their proper home
positions if they both move to 12 o’clock. If the hands
are not positioned correctly, use D (+) and B (–) to
move them to 12 o’clock.

2. Hold down B for about three seconds until the watch
beeps.
• This will make the World Time City (NYC in this
example) your new Home City. At the same time, it will
change the Home City you had selected prior to step
2 (TYO in this example), your World Time City.
• After swapping the Home City and World Time City,
the watch will stay in the World Time Mode. The
xSecond Hand will point to your new World Time City
(TYO in this example).
