This watch receives a time calibration signal and updates
its time setting accordingly. The time calibration signal
includes both Standard Time and Daylight Saving Time
(summer time) data.

• This watch is designed to pick up the time calibration
transmitted in Japan (Fukuoka/Saga and Fukushima)
and the United States (Fort Collins, Colorado).

• See the information under “Signal Receive
Troubleshooting” (page E-26) 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 (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
current digital time and date manually” (page E-40) 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 Amer ica” in this manual refers to the area that consists of
Canada, the continental United States, and Mexico.

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 six
times a day. When any auto receive is successful, remaining auto receive
operations are not performed. For more information, see “About Auto Receive”
(page E-20).

• Manual Receive

Manual receive lets you start a time calibration signal reception with the press of a
button. For more information, see “To perform manual receive” on page E-23.

E-15

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 pointing 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.

• Proper signal reception can be difficult or even impossible under the conditions listed
below.

Inside or
among
buildings

• Signal reception normally is better at night than during the day.

• Time calibration signal reception takes from two to seven minutes, but in some

cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.

• Signal reception may not be possible at the distances that are further than those
noted below during certain times of the year or day. Radio interference also may
cause problems with reception.

Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)

• Even when the watch is within the reception range of the transmitter, signal
reception will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.

• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.

About Auto Receive

With Auto Receive, the watch performs the receive operation each day automatically
up to six times between the hours of midnight and 5 a.m. (according to the
Timekeeping Mode time). When any receive operation is successful, none of the other
receive operations for that day are performed.

E-20

Note

• When a calibration time is reached, the watch will receive the calibration signal only
if it is in either the Timekeeping Mode or World Time Mode. Reception is not
performed if a calibration time is reached while you are configuring settings.

• Auto receive of the calibration signal is designed to be performed early in the
morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can receive the signal easily.

• Remember that reception of the calibration signal depends on the current time in
your Home City, as kept in the Timekeeping Mode.

E-21

About the Receiving Indicator

The receiving indicator shows the strength of the calibration signal being received. For
best reception, be sure to keep the watch in a location where signal strength is
strongest.

Receiving indicator

Weak

• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.

• Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal reception.

Signal Receive Troubleshooting

Check the following points whenever you experience problems with calibration signal
reception.

Problem

Cannot perform
manual receive.

Auto receive is
turned on, but
the Level 3
indicator does
not appear on
the display.

Probable Cause

• The watch is not in the Timekeeping
Mode.

• Your Home City is a city code that does
not support signal reception.

• You changed the time setting manually.

• The watch was not in the Timekeeping

or World Time Mode, or you performed
some button operation during auto
receive.

What you should do

• Enter the Timekeeping Mode
and try again (page E-23).

• Select one of the following city
codes as your Home City
(page E-12): SEL, TYO, YVR,

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary
battery) that is charged by the electrical power produced by the solar cell. The
illustration shown below shows how you should position the watch for charging.

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 cell is
blocked by clothing, etc.

• You should tr y to keep the watch
outside of your sleeve as much as
possible. Charging is reduced
significantly if the face is even only
partially covered.

E-48

Solar cell

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 normally is exposed to bright light
whenever possible.

• This watch uses a special rechargeable battery to store power produced by the solar
cell, 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.

• Never try to remove or replace the watch’s special battery yourself. Use of the wrong
type of battery can damage the watch.

• The current time and all other settings return to their initial factory defaults whenever
battery power drops to Level 5 (page E-50) and when you have the battery replaced.

• Turn on the watch’s Power Saving function (page E-55) and keep it in an area
normally exposed to bright light when storing it for long periods. This helps to keep
the rechargeable battery from going dead.

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.
Also note that allowing the watch to become very hot can cause its liquid crystal
display to black out. The appearance of the LCD should become normal again when
the watch returns to a lower temperature.

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

Auto Return Features

• If you leave the watch in the Alarm or Hand Setting Mode for two or three minutes
without performing any operation, it will return to the Timekeeping Mode automatically.

• If you leave the watch with a flashing setting on the display for two or three minutes
without performing any operation, it will exit the setting mode automatically.

Scrolling

The B and D buttons are used in various modes to scroll through data on the
display. In most cases, holding down these buttons during a scroll operation scrolls
through the data at high speed.

Initial Screens

When you enter the World Time Mode, the data you were viewing when you last exited
the mode will appear first.

E-58

Radio-controlled Timekeeping Precautions

• Strong electrostatic charge can cause the time setting to be thrown off.

• Even when the watch is within the reception range of the transmitter, signal

reception will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.

• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.

• 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.

E-59

• 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 cannot be performed starting from January 1, 2100.

• This watch can receive signals that differentiate between leap years and non-leap
years.

• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.

• Normally, the signal reception date shown by the Last Signal screen is the date data
included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows the date as kept in the Timekeeping Mode at
the time of signal reception.

• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time with the precision noted in “Specifications”.

• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code, DST (summer
time) (page E-44), and auto receive settings (page E-24). The following are the initial
factory defaults for these settings.

Transmitters

The time calibration signal received by this watch depends on the currently
selected Home City code (page E-12).

• When a U.S. time zone is selected, the watch receives the time calibration signal
transmitted from the United States (Fort Collins).

• When a Japanese time zone is selected, the watch receives the time calibration
signals transmitted from Japan (Fukushima and Fukuoka/Saga).

while the current count is in the range of 30 to 59

• The letters “UTC” is the abbreviation for “Universal Time Coordinated”, which 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.

12-hour/24-hour Timekeeping Formats

The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode also is
applied in all other modes.

• When you are using 12-hour timekeeping, a PM indicator (PM) appears in the upper
left display between noon and 11:59 p.m. No indicator is displayed between midnight
and 11:59 a.m.

• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.

Illumination Precautions

• Illumination may be hard to see when viewed under direct sunlight.

• Illumination turns off automatically whenever an alarm sounds.

• Frequent use of illumination runs down the battery.

• Watches that do not have WATER RESIST or WATER RESISTANT marked on the
back cover are not protected against the effects of sweat. Avoid using such a watch
under conditions where it will be exposed to large amounts of sweat or moisture, or
to direct splashing with water.

• Even if a watch is water-resistant, do not operate its buttons or crown while it is
submersed in water or wet.

• Even if a watch is water-resistant, avoid wearing it in the bath or in areas where
detergents (soap, shampoo, etc.) are being used. Such conditions can reduce water
resistance.

• After submersion in seawater, use plain water to rinse all salt and dirt from the
watch.

• In order to maintain water resistance, have the gaskets of your watch replace
periodically (about once every two or three years).

• A trained technician will know how to check your watch for proper water resistance
whenever you have its battery replaced. Battery replacement requires the use of
special tools. Always request battery replacement from your original retailer or from
an authorized CASIO Service Center.

E-67

• Some water-resistant watches come with fashionable leather bands. Avoid
swimming, washing, or any other activity that causes direct exposure of a leather
band to water.

• The inside surface of the watch glass may fog when the watch is exposed to a
sudden drop in temperature. No problem is indicated if the fogging clears up
relatively quickly. If the fogging does not clear or if water has gotten into the watch,
take the watch in for repair immediately.

• Continued use of the watch with water inside can result in damage to electronic and
mechanical components, the face of the watch, etc.

• Your water-resistant watch has been tested in accordance with the International
Organization for Standardization regulations ISO2281 and FTC (USA) “GUIDE FOR
THE WATCH INDUSTRY.” Guide 5.

Band

• Tightening the band too tightly can cause you to sweat and make it hard for air to
pass under the band, which can lead to skin irritation. Do not fasten the band too
tightly. There should be enough room between the band and your wrist so you can
insert your finger.

E-68

• Deterioration, rust, or corrosion of the band can cause it to break, which may result
in the watch falling off your wrist and becoming lost. Be sure to take good care of the
band and keep it clean. Should you notice any breakage, discoloration, looseness or
other problem with the band, immediately contact your original retailer or an
authorized CASIO Service Center to have it checked, repaired, or replaced. Note
that you will be charged for any repair or replacement of the band.

Temperature

• Never leave the watch on the dashboard of a car, near a heater, or in any other
location that is subject to very high temperatures. Do not leave the watch where it
will be exposed to very low temperatures, either. Temperature extremes can cause
the watch to lose or gain time, to stop, or otherwise malfunction.

• Leaving the watch in an area hotter than +60°C (140°F) for long periods can lead to
problems with its LCD. The LCD may become difficult to read at temperatures lower
than 0°C (32°F) and greater than +40°C (104°F).

E-69

Impact

• Your watch is designed to withstand impact incurred during nor mal daily use and
light activity such as playing catch, tennis, etc. Dropping the watch or otherwise
subjecting it to strong impact, however, can lead to malfunction.
Note that watches with shock-resistant designs (G-SHOCK, Baby-G, G-ms) can be
worn while operating a chain saw or engaging in other activities that generate strong
vibration, or while engage in strenuous sports activities (motocross, etc.).

Magnetism

• The hands of analog and combination (analog-digital) watches are moved by a
motor that uses magnetic force. When such a watch is close to a device (audio
speakers, magnetic necklace, cell phone, etc.) that emits strong magnetism, the
magnetism can cause timekeeping to slow down, speed up, or stop, resulting in the
incorrect time being displayed.

E-70

Electrostatic Charge

• Exposure to very strong electrostatic charge can cause the watch to display the
wrong time. Very strong electrostatic charge even can damage electronic
components.

• Electrostatic charge can cause the display to go blank momentarily or cause a
rainbow effect on the display.

Chemicals

• Do not allow the watch to come into contact with thinner, gasoline, solvents, oils, or
fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain
such ingredients. Doing so can cause discoloration of or damage to the case, resin
band, leather band, and other parts.

Storage

• If you do not plan to use the watch for a long time, wipe it thoroughly free of all dirt,
sweat, and moisture, and store it in a cool, dry place.

E-71

Resin Components

• Allowing the watch to remain in contact with other items or storing it together with
other items for long periods while it is wet can cause the color of the other items to
transfer to the resin components of the watch. Be sure to dry off the watch
thoroughly before storing it and make sure it is not in contact with other items.

• Leaving the watch where it is exposed to direct sunlight (ultraviolet rays) for long
periods or failure to clean dirt from the watch for long periods can cause it to
become discolored.

• Friction caused by certain conditions (frequent external force, sustained rubbing,
impact, etc.) can cause discoloration of painted components.

• If there are printed figures on the band, strong rubbing of the printed area can cause
discoloration.

• Failure to clean dirt from the watch for long periods can cause fluorescent color to
fade. Wash dirt off with water as soon as possible and then dry the watch.

• Semi-transparent resin parts can become discolored due to sweat and dirt, and if
exposed to high temperatures for long periods.

• Contact an authorized CASIO Service Center to have resin components replaced.
Note that you will be charged for replacement costs.

E-72

Natural Leather and Imitation Leather Bands

• Allowing the watch to remain in contact with other items or storing it together with
other items while it is wet for long periods can cause the color of the other items to
transfer to the natural leather or imitation leather band of the watch. Be sure to dry
off the watch thoroughly before storing it and make sure it is not in contact with other
items.

• Leaving a leather band where it is exposed to direct sunlight (ultraviolet rays) for
long periods or failure to clean dirt from a leather band for long periods can cause it
to become discolored.

Important!

• Subjecting a natural leather or imitation leather band to rubbing or dirt can cause
color transfer and discoloration.

Metal Components

• Failure to clean dirt from a metal band can lead to formation of rust, even if the band
is stainless steel or plated. If the watch is exposed to sweat or water, wipe it
thoroughly with a soft, absorbent cloth and then store it in a well-ventilated location
to dry.

E-73

• To clean the band, use a soft toothbrush or similar tool to scrub it with a weak
solution of water and a mild neutral detergent. Take care to avoid getting solution on
the watch case.

Bacteria and Odor Resistant Band

• The bacteria and odor resistant band protects against odor generated by the
formation of bacteria from sweat, which ensures good comfort and hygiene. In order
to ensure maximum bacteria and odor resistance, keep the band clean. Use an
absorbent soft cloth to wipe the band clean of dirt, sweat, and moisture. The bacteria
and odor resistant band suppresses the formation of organisms and bacteria. It does
not protect against rash due to allergic reaction, etc.

Display

• Display figures may be difficult to read when viewed from an angle.

E-74

User Maintenance

Caring for Your Watch

• A dirty or rusty case or band can soil the sleeve of your clothing, cause skin
irritation, and even interfere with watch performance. Be sure to keep the case and
band clean at all times. Rust tends to form easily after the watch is exposed to
seawater and then left without cleaning.

• Sometimes a smudge like pattern may appear on the surface of a resin band. This
will not have any affect on your skin or clothing. Wipe the band with a cloth to clean
it.

• Keep a leather band clean by wiping it with a dry cloth. Both resin bands and leather
band can become worn and cracked over time when subjected to normal daily use.

• Should your band become badly cracked or worn, be sure to have it replaced with a
new one. Request band replacement from your original retailer or an authorized
CASIO Service Center. Note that you will be charged for band replacement costs,
even if your watch is still covered by its warranty.

E-75

• Remember that you wear your watch next to your skin, just like a piece of clothing.
Because of this, you should always keep your watch clean. Use a soft, absorbent
cloth to wipe off any dirt, sweat, water, or other foreign matter from the case and
band.

Dangers of Poor Watch Care

Rust

• Though the stainless steel used for the watch is highly rust-resistant, rust can form if
the watch is not cleaned after it becomes dirty. Failure of oxygen to come into
contact with the metal because it is dirty causes breakdown of the oxidization layer
on the metal surface, which leads to the formation of rust.

• Even if the surface of the metal appears clean, sweat and rust in crevasses can soil
the sleeves of clothing, cause skin irritation, and even interfere with watch
performance.

Premature Wear

• Leaving sweat or water on a resin band or storing it an area subject to high moisture
can lead to premature wear, cuts, and breaks.

E-76

Skin Irritation

• Individuals with sensitive skin or in poor physical condition may experience skin
irritation when wearing a watch. Such individuals should keep their leather band or
resin band particularly clean, or switch to a metal band. Should you ever exper ience
a rash or other skin irritation, immediately remove the watch and contact a skin care
professional.

Battery

• 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 rechargeable battery is charged when the solar cell is exposed to light, and so
regular periodic replacement is not required. However, charging and discharging of
the battery over the years leads naturally to a loss in its ability to sustain a charge
and shortens its operating time. If this happens, contact your original retailer or
authorized CASIO Service Center.
