purchase, be sure to read this manual carefully.

Mean Time differential of –3.5 hours. Because of this, the radio-controlled
atomic timekeeping function will not display the correct time for
Newfoundland, Canada.

Bright light
Solar cell
Keep the watch exposed to bright light
The electricity generated by the solar cell 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.
Warning!
• The measurement functions built into this watch are not intended for use in taking
measurements that require professional or industrial precision. Values produced
by this watch should be considered as reasonably accurate representations only.
• The Tide Graph displayed by this watch is not intended for navigational purposes.
Always use proper instruments and resources to obtain data for navigation
purposes.
• This watch is not an instrument for calculating low tide and high tide times. The
Tide Graph of this watch is intended to provide a reasonable approximation of
tidal movements only.
• CASIO COMPUTER CO., LTD. assumes no responsibility for any loss, or any
claims by third parties that may arise through the use of this watch.
• 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 cause 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.

• About 1.5 seconds after you enter the World Time Mode or Alarm Mode from
another mode, the watch’s hands will start to move to the time setting for the mode
you entered. All button operations are disabled while the hands are moving. If you
need to pass through the World Time Mode or the Alarm Mode to get to another
mode (such as when going from the Tide Graph Mode to the Timekeeping Mode),
press C (mode change) to advance to the next mode before the hands start
moving. Once the hands do start moving, you will need to wait until they stop before
you can advance to the next mode.
Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
• Supported time calibration signals: Germany (Mainflingen), England (Anthorn),
United States (Fort Collins), Japan (Fukushima or Fukuoka/Saga).
• See the information under “Signal Reception Troubleshooting” if you experience
problems with time calibration signal reception.
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 will normally use the watch. For more
information, see “To specify your Home City”.
• 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
“Timekeeping”
for more information about manual time settings.
• 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.
To specify your Home City
1.In the Timekeeping Mode, hold down A for about five
seconds until the watch beeps twice. This indicates the
watch is in the setting mode.
•
Entering the setting mode will cause the stopwatch
second hand to move to the city code of the currently
selected Home City.
2.Use D to change the Home City setting.
• Each press of D causes the stopwatch second hand
to advance clockwise to the next city code.
• All hands (except for the second hand) and the date
display will change automatically to the applicable
settings for the currently selected city code. All button
operations are disabled while the hands and date
display are changing.
• Time calibration signal reception is supported when
any one of the city codes shown in the table below is
selected as your Home City.

• In addition to the above, you also can select city codes that are outside the ranges
of the time calibration signal transmitters supported by this watch.
• Note that this watch does not have a city code that corresponds to Newfoundland.
3. After the Home City setting is the way you want, press 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 or you can set the time
manually.
