Getting Acquainted
Solar panel
The electricity generated by the solar panel of the watch is
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. Even if the face of the watch is
blocked only partially from light, charging will be reduced
significantly.

• 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 to be 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.

Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration
signal. You also can perform a manual procedure to set the time and date, when
necessary.
• The first thing you should do after purchasing this watch is to specify your
Home City, which is the city where you normally will use the watch. For more
information, see “To specify your Home City” on page E-12.
• When using the watch outside the areas covered by the time signal transmitters, you
will have to adjust the current time setting manually as required. See “Configuring
Time and Date Settings Manually” (page E-41) for more information about manual
time settings.

To specify your Home City
1. In the Timekeeping Mode, keep A depressed (for
about five seconds) as the second hand moves to the
last signal reception result (“Y” or “N”), then to “READY”
(or “R” for some models), and then to the city code of
the currently selected Home City.
• This indicates the city code setting mode.
2. Use D to move the second hand clockwise to the city
code you want to use as your Home City.
• For information about the Home City, see “Home City
Codes and Transmitters” (page E-13). The watch will
receive the time calibration signal of the transmitter of
the selected city code.
City code
3. After the Home City setting is the way you want, press
Second hand
A to return to the Timekeeping Mode.
• Normally, your watch should show the correct time as soon as you specify your
Home City code. If it does not, it should adjust automatically after the next auto
receive operation. You also can perform manual receive (page E-26) or you can set
the time manually (page E-41).
• Even if the time calibration signal is received correctly, there are some times when
the analog hands may not indicate the correct time. If this happens, use the
procedures under “Auto Hand Home Position Correction” (page E-45) to check the
home positions of the hands, and make adjustments as required.
Home City Codes and Transmitters
• The time calibration signal the watch will attempt to pick up depends on its current
Home City code setting as shown below. If you use the watch in Japan or Europe
(each of which has two different transmitter locations), it will try to receive the time
calibration signal from one of the transmitters in your current location. If it cannot
receive the signal, it will then try to receive the time calibration signal from the other
transmitter.

the time calibration signal transmitters supported by this watch.
• Note that this watch does not have a city code that corresponds to Newfoundland.
• The U.S. time calibration signal can be picked up by the watch while in North
America. The term “North America” in this manual refers to the area that consists of
Canada, the continental United States, and Mexico.
• As of December 2010, China does not use Daylight Saving Time (DST). If China
does go to the Daylight Saving Time system in the future, some functions of this
watch may no longer operate correctly.
• Using this watch in a country covered by a time calibration that is different from the
countries it supports may result in incorrect time indication due to local application of
summer time, etc.

Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
If your Home Time city code is one that supports time calibration signal reception
(except for China), the watch will automatically switch between standard time and
summer time in accordance with the signal data. For other city codes, you will need to
switch manually.
• For information about the DST setting, see “To set your Home City time” (page
E-38).
• As of December 2010, China does not use Daylight Saving Time (DST). If China
does go to the Daylight Saving Time system in the future, some functions of this
watch may no longer operate correctly.

Operation Guide 5179
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to six
times a day (five times for the China signal). When any auto receive is successful, the
remaining auto receive operations are not performed. For more information, see
“About Auto Receive” (page E-23).
Important!
• When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side facing towards a window.
This watch is designed to receive a time calibration signal late at night. Because of
this, you should place the watch near a window as shown in the illustration when you
take it off at night. Make sure there are no metal objects nearby.
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive” (page E-26).

About Auto Receive
The watch receives the time calibration signal automatically up to six times a day (five
times for the China signal). When any auto receive is successful, the remaining auto
receive operations are not performed. The reception schedule (calibration times)
depends on your currently selected Home City, and whether standard time or Daylight
Saving Time is selected for your Home City.

Strong magnetism or impact can cause the hands and/or day setting to be off, even if
the watch is able to perform the signal receive operation. Auto hand home position
correction corrects the hand position automatically.
• Auto correction is performed in the Timekeeping Mode only.
• The auto correction operation corrects the positions of the second, minute, and hour
hands. Home position correction of the dial hands and day must be performed
manually, using the procedure under “Manual Home Position Correction” (page
E-48).
• Each hour, the watch performs automatic correction of the hand positions.
Correction can be performed for error up to 55 minutes slow or 5 minutes fast.
• You also can trigger the auto hand home position correction operation manually, if
you want. See “To trigger the auto hand home position correction operation
manually” (page E-46) for more information.
• The auto hand home position correction operation can take up to three and a half
minutes to complete.

To trigger the auto hand home position correction operation manually
• Perform the following procedure when the time setting is
off.
In the Timekeeping Mode, hold down D for about six
seconds until the second hand completes one full
revolution.
• Though the second hand will stop momentarily about
three seconds after you hold down D, do not release
the button yet. Wait until the second hand completes a
full revolution before you release D.
• To interrupt an ongoing correction operation and return
to the Timekeeping Mode, press D again.
• If you release D when the second hand stops the first time (after about three
seconds) in the above operation, the watch will enter the manual home position
correction mode, which is described under “Manual Home Position Correction” (page
E-48). If this happens, press A to return to the Timekeeping Mode and then perform
the above operation again.
The manually triggered auto home position correction operation performs the following
two steps.
1. The hands will move automatically in order to determine the home positions of the
watch.
2. After the hand home positions are determined, the watch will return to normal
timekeeping automatically. This completes the correction operation.

Manual Home Position Correction
Strong magnetism or impact can cause the hands and/or day setting to be off, even if
the watch is able to perform the signal receive operation. If this happens, perform the
following home position correction procedure.
• Hand home position correction is not required if the time and day settings are
correct.
• You also can use auto hand home position correction (page E-45) to correct the
home positions of the second, minute, and hour hands.
1. In the Timekeeping Mode, hold down D for about three
seconds until the second hand stops. Release D at
this time.
• Each press of C cycles through available settings in the sequence shown below.

Power Supply
This watch is equipped with a solar panel and a special rechargeable battery
(secondary battery) that is charged by the electrical power produced by the solar
panel. The illustration shown below shows how you should position the watch for
charging.
Solar panel
Example: Orient the watch so its face is
pointing at a light source.
• The illustration shows how to position
a watch with a resin band.
• Note that charging efficiency drops
when any part of the solar panel is
blocked by clothing, etc.
• You should try to keep the watch
outside of your sleeve as much as
possible. Even if the face of the watch
is blocked from light only partially,
charging will be reduced significantly.

Important!
• 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. Make sure that the watch is exposed to bright light whenever
possible.
• This watch uses a special rechargeable battery to store power produced by the solar
panel, 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 special rechargeable battery to charge fully, contact
your dealer or CASIO distributor about having it replaced.
• The special rechargeable (secondary) battery used by your watch is not intended to
be removed or replaced by you. Use of a rechargeable battery other than the special
one specified for this watch can damage the watch.
• The current time and all other settings return to their initial factory defaults whenever
the watch is left uncharged for about one week after battery power drops to Level 3,
and when you have the battery replaced.
• Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to keep the rechargeable battery from going dead.
Jumps two seconds
• The second hand jumping every two seconds (Level 2) indicates that battery power
is quite low. Expose the watch to light as soon as possible to charge the battery.
E-54
E-55
• When battery power is at Level 2, time calibration signal reception is disabled.
• 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. If the watch is left uncharged for
about one week after battery power drops to Level 3, the current time and all other
settings return to their initial factory defaults.
Charging Precautions
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.
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
Charging Guide
After a full charge, timekeeping remains enabled for up to about five months.
• The following table shows the amount of time the watch needs to be exposed to light
each day in order to generate enough power for normal daily operations.

This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Features
• If you do not perform any operation for about two or three minutes in the current time
setting mode, or in the hand/day home position correction mode, the watch will
return to the Timekeeping Mode automatically.
• If you do not perform any operation for about two or three minutes while a setting
mode is selected, the watch will exit the setting mode automatically.
High-Speed Movement
• The above exposure time values are all for reference only. Actual required exposure
times depend on lighting conditions.
E-58
Reference
• In most cases when configuring settings, holding down a button will start high-speed
scrolling of the applicable setting.
• High-speed movement of hands and day will continue until you press any button.
E-59
Operation Guide 5179
Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• The time calibration signal bounces off the ionosphere. Because of this, such factors as
changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to
higher altitudes due to seasonal atmospheric changes or the time of day may change
the reception range of the signal and make reception temporarily impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make manually.
• The watch is designed to update the date and day of the week automatically for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal will not be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time with the precision noted in “Specifications”.
Timekeeping
• 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 normally should be no reason
to change it. Note, however, that if the watch is left uncharged for about one week
after battery power drops to Level 3, the current time and all other settings return to
their initial factory defaults.
• The date will change automatically when the current time reaches midnight. The
date change at the end of the month may take more time than normal.
• The current time for all time zones in the Timekeeping Mode and World Time Mode
is calculated in accordance with the Coordinated Universal Time (UTC) offset of
each zone, based on your Home Time Zone time setting.
• UTC is the world-wide scientific standard of timekeeping. It is based upon carefully
maintained atomic (cesium) clocks that keep time accurately to within microseconds.
Leap seconds are added or subtracted as necessary to keep UTC in sync with the
Earth’s rotation. The reference point for UTC is Greenwich, England.

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.
• There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area.
• Press any button.
