Congratulations upon your selection of this CASIO watch.
x Note that the product illustrations in this manual are intended for reference only, and so the actual
product may appear somewhat different than depicted by an illustration.
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.

Charging the Watch
E-34 Specifications
The face of the watch is a solar panel 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.
Charging Guide
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
x 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.
x The watch may enter a sleep
state (page E-10) if its face is
blocked by your sleeve even
only partially.
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.
x On the dashboard of a car parked in direct sunlight
x Too close to an incandescent lamp
x Under direct sunlight
E-6
E-7
Operation Guide 5235 (OC)
Important!
x 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.
x 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.
Power Recovery Mode
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 continuous signal reception or other operations over a
short period. Note that all operations are disabled while the watch is in the power recovery mode.
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.
Power Levels
B
+
You can get an idea of the watch’s power level by observing the movement of
the x Second Hand.
x If the x Second Hand is moving normally at one-second intervals, power is
at Level 1.
x If the x Second 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 (Low battery alert).

Power Saving
Radio Controlled Atomic Timekeeping
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.
x There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark
Operation
60 to 70 minutes (second hand sleep)
x Second Hand only stopped at 12 o’clock, all other functions enabled

x All functions, including timekeeping, disabled
x Internal timekeeping maintained
x 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.
To recover from the sleep state
Move the watch to a well-lit area or press any button.
This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See “Configuring Current Time and Date Settings Manually” (page E-23) for more
information.
This section explains how the watch updates its time settings when the city code selected as the Home
City is in Japan, North America, Europe, or China, and is one that supports time calibration signal
reception.
If your Home City Code setting is this:
The watch can receive the signal from the transmitter

Troubleshooting
Hand Movement and Position
■ The x Second Hand is moving at two-second intervals.
■ All the watch’s hands are stopped at 12 o’clock and none of the buttons work.
Power may be low. Expose the watch to light until the x Second Hand starts moving normally, at onesecond intervals (page E-8).
■ The hands of the watch suddenly start moving at high speed, even when I do not perform any
operation.
This could be due to any one of the following causes. In all cases, the hand movement does not indicate
malfunction, and should stop shortly.
x The watch is recovering from a sleep state (page E-10).
x The time setting is being adjusted following a successful auto time calibration signal receive operation
(page E-11).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-9). Do not perform any operation until the hands
return to their normal positions (in about 15 minutes). The hands should return to their correct positions
when normal operation returns. To help power recover, leave the watch in a location where it is exposed
to light.
>
4. Check the v Day Indicator to confirm that it is 1, which is its home position.
x If the 1 is not in the center of the v Day Indicator, rotate the crown to
center it.
x Rotating the crown three full consecutive turns clockwise will cause the
v Day Indicator to start changing in a forward direction (increment).
x To stop v Day Indicator movement, press any button.
5. Push the crown back in to return to regular timekeeping.
x This will cause the hands to return to their normal positions and resume
regular timekeeping. Wait until everything stops moving before performing
any other operation.
E-29
■ The current time setting is off by one hour.
x If you are using the watch in an area where time calibration signal reception is possible, see “To
configure Home City settings” (page E-19).
x The period when summer time is applied in the location where you are using the watch may be
different from the period set for your currently selected Home City. Use the procedure under “To switch
between standard time and summer time manually” (E-21) to switch from AUTO to STD (for standard
time) or DST (for summer time).
■ The hands and/or day indicator is off.
This could indicate that the watch has been exposed to magnetism or strong impact, which has caused
problems with proper hand and day indicator alignment. Adjust the watch’s hand and day indicator home
position alignment (page E-27).
Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-8). Continue exposing the watch to light
until the x Second Hand starts moving normally (at one-second intervals).
■ The x Second Hand starts to move at one-second intervals, but then suddenly returns to moving
at two-second intervals.
The watch probably is not sufficiently charged yet. Continue keeping it exposed to light.
■ The current time setting is off by hours.
x Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary (page
E-19).

■ The current time setting changes after I set it manually.
You may have the watch configured for Auto Receive of the time calibration signal (page E-14), which will
cause the time to be adjusted automatically according to your currently selected Home City. If this results
in the wrong time setting, check your Home City setting and correct it, if necessary (page E-19).

from AUTO to STD (for standard time) or DST (for
summer time).
