Applications

The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude. Measured values are then shown on the display. Such features make this watch useful when hiking, mountain climbing, or when engaging in other such outdoor activities.

• The measurement functions built into this watch are not intended for taking measurements that

require professional or industrial precision. Values produced by this watch should be considered as reasonable representations only.

•

When engaging in mountain climbing or other activities in which losing your way can create a dangerous or life-threatening situation, always use a second compass to conﬁ rm direction readings.

• 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.

About This Manual

• Depending on the model of your watch, digital display text appears

either as dark ﬁ gures on a light background, or light ﬁ gures on a dark background. All examples in this manual are shown using dark ﬁ gures on a light background.

• Button operations are indicated using the letters shown in the

illustration.

• 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.

ENGLISH

Important!

• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure

readings produced by its pressure sensor. This means that readings taken at different times at the same location may produce different altitude values due to changes in barometric pressure. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located.

• When using the altimeter of this watch for mountain climbing or other activities, it is highly

recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly calibrate the altimeter with the latest information. For more information, see “To specify a reference altitude value” (page E-61).

• Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other

activities, be sure always to take along another compass to conﬁ by the digital compass of this watch are different from those of the other compass, perform bidirectional calibration of the digital compass to ensure more accurate readings.

Important!

• 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.

• Turn on the watch’s Power Saving function (page E-13) and keep it 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. Expose the watch to bright light whenever possible.

Power Levels

You can get an idea of the watch’s power level by observing the battery power indicator on the display.

Charging the Watch

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, leave it in a location where it is exposed to light.

• Best charging performance is

achieved by exposing the watch to the strongest light available.

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

Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).

•

• Leaving the watch exposed to direct sunlight or some other very strong light source can cause the

battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.

• All data stored in memory is deleted, and the current time and all other settings return to their initial

factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.

Power Recovery Mode

• Performing multiple sensor, illumination, or beeper operations during a short period may cause all of

the battery power indicators (H, M, and L) to start ﬂ ashing on the display. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor operations will be disabled until battery power recovers.

• Battery power will recover in about 15 minutes. At this time, the battery power indicators (H, M, L) will

stop ﬂ ashing. This indicates that the functions listed above are enabled again.

Radio Controlled Atomic Timekeeping

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 “Conﬁ guring Current Time and Date Settings Manually” (page E-30) 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:

LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW Anthorn (England), Mainﬂ ingen (Germany)

Power Saving

When turned on, 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 information about enabling and disabling power saving, see “To turn Power Saving on and off”

(page E-97).

• There actually are two sleep state levels: “display sleep” and “function sleep”.

• Even when the watch is within range of a transmitter, signal reception may be impossible due to the

effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the inﬂ

uence of the conditions listed above becomes even greater.

• Signal reception may not be possible at the distances noted below during certain times of the year or

day. Radio interference may also cause problems with reception.

Radio-controlled Atomic Timekeeping Precautions

• Strong electrostatic charge can result in the wrong time setting.

• Even if a receive operation is successful, certain conditions can cause the time setting to be off by up

to one second.

• The watch is designed to update the date and day of the week automatically for the period January 1,

2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.

• If you are in an area where signal reception is not possible, the watch keeps time with the precision

noted in “Speciﬁ cations”.

The receive operation is disabled under any of the following conditions.

•

– While power is at Level 3 (L) or lower (page E-10) – While the watch is in the power recovery mode (page E-11) – While a direction, barometric pressure/temperature, or altitude reading operation is in progress – When the watch is in the function sleep state (“Power Saving”, page E-13) – While barometric pressure change indicator is being measured – While a trek log updating is enabled – While a countdown timer operation is in progress (page E-84)

• A receive operation is cancelled if an alarm sounds while it is being performed.

Taking Direction Readings

The Digital Compass Mode uses a built-in direction sensor to take direction readings and display the results. North is indicated by three graphic segments ( the bearing and the bearing angle to your objective.

• For information about what you can do to improve digital compass reading accuracy, see “Calibrating

the Bearing Sensor” (page E-35) and “Digital Compass Precautions” (page E-42).

To take a direction reading

1. Make sure the watch is in the Timekeeping Mode or any one of the sensor modes.

• The senso r modes are: Digit al Compass M ode, Baromete r/Therm ometer Mod e, and Altimete r

Mode

2. Place the watch on a ﬂ at surface. If you are wearing the watch, make sure that your wrist is horizontal (in relation to the horizon).

3. Point the 12 o’clock position of the watch in the direction whose reading you want to take.

The margin of error for the bearing angle and the literal direction indication to your objective is ±11

degrees while the watch is horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 304 to 326 degrees.

• Note that taking a direction reading while the watch is not horizontal (in relation to the horizon) can

result in large direction reading error. You can calibrate the bearing sensor if you suspect the direction reading is incorrect.

• See “Digital Compass Precautions” (page E-42) for important information about taking direction readings.

Calibrating the Bearing Sensor

You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. You can use any one of two different bearing sensor calibration methods: bidirectional calibration or magnetic declination correction.

Bidirectional Calibration

•

Bidirectional calibration calibrates the bearing sensor in relation to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed to magnetic force. This type of calibration should be used if the watch becomes magnetized for any reason.

Important!

• To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before

using it. The watch may produce incorrect direction readings if you do not perform bidirectional calibration.

Magnetic Declination Correction

•

With magnetic declination correction, you input a magnetic declination angle (difference between magnetic north and true north), which allows the watch to indicate true north. You can perform this procedure when the magnetic declination angle is indicated on the map you are using. Note that you can input the declination angle in whole degree units only, so you may need to round off the value speciﬁ ed on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.

Precautions about bidirectional calibration

You can use any two opposing directions for bidirectional calibration. You must, however, make sure

•

that they are 180 degrees opposite each other. Remember that if you perform the procedure incorrectly, you will get wrong bearing sensor readings.

• Do not move the watch while calibration of either direction is in progress.

• You should perform bidirectional calibration in an environment that is the same as that where you plan

to be taking direction readings. If you plan to take direction readings in an open ﬁ calibrate in an open ﬁ eld.

Setting a map and ﬁ nding your current location

Having an idea of your current location is important when mountain climbing or hiking. To do this, you need to “set the map”, which means to align the map so the directions indicated on it are aligned with the actual directions of your location. Basically what you are doing is aligning north on the map with north as indicated by the watch.

• Note that map reading skills and experience are required to determine your current location and

destination on a map.

Location

• Taking a direction reading when you are near a source of strong magnetism can cause large errors in

readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.)

• Accurate readings are impossible indoors, especially inside ferroconcrete structures. This is because

the metal framework of such structures picks up magnetism from appliances, etc.

• Accurate direction readings are also impossible while in a train, boat, air plane, etc.

The northerly direction can be expressed either as magnetic north or true north, which are different from each other. Also, it is important to keep in mind that magnetic north moves over time.

• Magnetic north is the north that is indicated by the needle of a compass.

• True north, which is the location of the North Pole of the Earth’s axis, is the

north that is normally indicated on maps.

• The difference between magnetic north and true north is called the

“declination”. The closer you get to the North Pole, the greater the declination angle.

Example: Advancing to an objective while monitoring the direction to it

Even if you lose sight of your objective, you can use a map to store the required bearing in bearing memory and refer to the memorized information to advance to your objective.

1. Set the map (page E-40).

2. Without changing the orientation of the map, place the watch on it at your current location, and point 12 o’clock at your desired objective on the map.

3. With the 12 o’clock position of the watch pointed towards your objective on the map, press C.

• The watch sta rts taking di rection reading s, with the ﬁ rst res ult appearing a fter about o ne second.

4. During the approximately 60 seconds that direction readings are being taken, press E to store the bearing direction in memory.

• To recall a stored bear ing and display its li teral direction in dication and b earing angle, pre ss C.

Now you can advance towards your objective while observing the stored direction on the watch display.

Important!

• As you progress, the direction to your bearing will change, so you need to keep updating the

information in bearing memory.

E-41

Storage

• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of

this, you should store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), and household appliances (TVs, personal computers, washing machines, freezers, etc.)

• Whenever you suspect that the watch may have become magnetized, perform the procedure under “To

perform bidirectional calibration” (page E-37).

Pressure Sensor and Temperature Sensor Calibration

The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally require no further adjustment. If you notice serious errors in the pressure readings and temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

Important!

• Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before

performing the calibration procedure, compare the readings produced by the watch with those of another reliable and accurate barometer.

• Incorrectly calibrating the temperature sensor can result in incorrect readings.

Carefully read the following before doing anything. –

Compare the readings produced by the watch with those of another reliable and accurate thermometer.

– If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the

temperature of the watch time to stabilize.

E-52

Barometer and Thermometer Precautions

• The pressure sensor built into this watch measures changes in air pressure, which you can then apply

to your own weather predictions. It is not intended for use as a precision instrument in ofﬁ cial weather prediction or reporting applications.

• Sudden temperature changes can affect pressure sensor readings. Because of this, there may be

some error in the readings produced by the watch.

• Temperature reading are affected by your body temperature, direct sunlight, and moisture. To achieve

a more accurate temperature reading, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the surrounding temperature.

To calibrate the pressure sensor and the temperature sensor

1. Take a reading with another measurement device to determine the exact current barometric pressure or temperature.

Using the Altimeter Mode

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor.

• The displayed altitude reading is a relative altitude that is calculated based on measurement of

changes in barometric pressure by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at different times at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located.

• When using the altimeter of this watch for mountain climbing or other activities, it is highly

recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly calibrate the altimeter with the latest information.

Important!

• See “To specify a reference altitude value” (page E-61) and “Altimeter Precautions” (page E-71) for

information about how to minimize differences between readings produced by the watch and values provided by local altitude (elevation) indications.

Getting Ready

Before actually taking an altitude reading you need to select an altitude screen format and select an altitude reading interval.

Using Reference Altitude Values

To minimize the chance of reading error, you should update the reference altitude value before setting off on a trek or any other activity where you plan to take altitude readings. While mountain climbing, it is highly recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly update the reference altitude value with the latest information.

• Reading error can be caused by changes in barometric pressure, and by temperature changes due to

change in barometric pressure and/or elevation.

• Though altitude readings can be taken without setting a reference altitude, doing so may produce

readings that are very different from altitudes indicated by other altitude markers and indications.

• Before performing the procedure below, look up the altitude of your current location on a map, the

Internet, etc.

Types of Altitude Data

Your watch can record three types of altitude data in its memory: manually saved data, auto save values, and trek log values.

• Use the Data Recall Mode to view data stored in memory. See “Viewing Altitude Records” (page E-72)

for details.

Manually Saved Records

Any time you perform the procedure below in the Altimeter Mode, the watch will create and store a record with the currently displayed altitude reading, along with the date and time the reading was taken. There is enough memory to store up to 30 manually saved records, which are numbered from

Trek Log Values

While trek log updating is enabled, altitude values (high altitude/low altitude, cumulative ascent/descent) for a particular trek are automatically checked and updated at regular intervals, even if you exit the Altimeter Mode. Values include the date and time each is updated. Up to 14 records of trek log values can be maintained in memory, and each record is assigned a number from Mt.1 through Mt.14 in the sequence they are stored.

• For up to 12 hours after trek log value updating is enabled, the values are updated automatically even

• Trek log value updating stops automatically whenever the battery charge goes low.

Note

• Even if you exit the Altimeter Mode while trekking, updating of the trek log high altitude, low altitude,

and cumulative ascent and descent values continues.

• Your watch has enough memory for 14 trek log records, which means you can maintain values for up to

14 treks.

How does the altimeter work?

Generally, air pressure decreases as altitude increases. This watch bases its altitude reading on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO). These values deﬁ ne relationships between altitude and air pressure.

• Note that the following conditions will prevent you from obtaining accurate readings:

When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact

There are two standard methods of expressing altitude: absolute altitude, which expresses an absolute height above sea level, and relative altitude, which expresses the difference between the altitudes of two different places. This watch expresses altitudes as relative altitude.

(300 m) + e (620 m) = 920 m

(320 m) + r (500 m) = 820 m

• Logging of trek log data continues even if you exit the Altimeter Mode.

Note

• The high altitude, low altitude, total ascent, and total descent values are retained in memory when you

exit the Altimeter Mode. To clear values, perform the procedure under “To delete data in a speciﬁ memory area” (page E-76).

Altimeter Precautions

• This watch estimates altitude based on air pressure. This means that altitude readings for the same

location may vary if air pressure changes.

• Do not rely upon this watch for altitude reading or perform button operations while sky diving, hang

gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in any other activity where there is the chance of sudden altitude changes.

• Do not use this watch for measuring altitude in applications that demand professional or industrial level

precision.

• Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings

produced by this watch will not match the altitude readings announced or indicated by the ﬂ

The Effect of Temperature on Altitude Readings

For the more accurate altitude readings, leaving the watch on your wrist is recommended in order to maintain the watch at a constant temperature.

• When taking altitude readings, keep the watch at as stable a temperature as possible. Changes in

About the Auto Light Switch

Turning on the auto light switch causes illumination to turn on, whenever you position your wrist as described below in any mode.

Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.

Warning!

Always make sure you are in a safe place whenever you are reading the display of the watch

•

using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding

•

on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a trafﬁ c accident and serious personal injury.

Illumination Precautions

• The LED that provides illumination loses power after very long use.

• 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.

Auto light switch precautions

• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can

cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display.

• Note that wearing the watch under your sleeve while the auto light switch is turned on can cause

frequent illumination of the display and can run down the battery.

• Illumination may not turn on if the face of the watch is more than 15 degrees above

or below parallel. Make sure that the back of your hand is parallel to the ground.

• Illumination turns off after the preset illumination duration (page E-92), even if you

keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with proper operation of the auto

light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.

• You may notice a very faint clicking sound coming from the watch when it is shaken

back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.

If you are using the watch in an area where time calibration signal reception is possible, see “To conﬁ gure Home City and summer time settings” (page E-28). If you are using in the watch in an area where time calibration signal reception is not possible, you may need to change your Home City’s standard time/daylight saving time (DST) setting manually. Use the procedure under “To change the current time and date settings manually” (page E-30) to change the standard time/daylight saving time (DST) setting.

Power saving on indicator

I can’t get correct altitude readings.

■

Relative altitude is calculated based on changes in barometric pressure measurement by its pressure sensor. This means that barometric pressure changes can cause readings taken at different times at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the altimeter of this watch for mountain climbing or other activities, it is highly recommended that you check a map, local altitude indications, or some other source for your current correct altitude and regularly calibrate the altimeter with the latest information. For more information, see “To specify a reference altitude value” (page E-61).

Do not use your watch for scuba diving or other types of diving that requires air tanks.

•

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.

5BAR 10BAR 20BAR

E-108

•

Even if a watch is water resistant, note the usage precautions described below. Such types of use

reduce water resistance performance and can cause fogging of the glass.

− Do not operate the crown or buttons while your watch is submersed in water or wet. Avoid wearing your watch while in the bath.

−

− Do not wear your watch while in a heated swimming pool, sauna, or any other high temperature/high humidity environment.

− Do not wear your watch while washing your hands or face, while doing housework, or while performing any other task that involves soaps or detergents.

•

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

•

To maintain water resistance, have the gaskets of your watch replaced periodically (about once every

two or three years).

•

A trained technician will inspect 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.

•

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. Sudden and extreme temperature changes (such as coming into an air conditioned room in the summer and standing close to an air conditioner outlet, or leaving a heated room in the winter and allowing your watch to come into contact with snow) can cause it to take longer for glass fogging to clear up. If glass fogging does not clear up or if you notice moisture inside of the glass, immediately stop using your watch and take it to your original retailer or to an authorized CASIO service center.

•

Your water-resistant watch has been tested in accordance with International Organization for

Standardization regulations.

E-110

OPUM-E

Band

•

Tightening the band too tightly can cause you to sweat and make it difficult 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.

•

Deterioration, rust, and other conditions can cause the band to break or come off of your watch, which in

turn can cause band pins to fly out of position or to fall out. This creates the risk of your watch falling from your wrist and becoming lost, and also creates the risk of personal injury. Always take good care of your band and keep it clean.

•

Immediately stop using a band if you even notice any of the following: loss of band flexibility, band

cracks, band discoloration, band looseness, band connecting pin flying or falling out, or any other abnormality. Take your watch to your original retailer or to a CASIO service center for inspection and repair (for which you will be charged) or to have the band replaced (for which you will be charged).

Temperature

•

Never leave your 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 your watch where it will be exposed to very low temperatures. Temperature extremes can cause your watch to lose or gain time, to stop, or otherwise malfunction.

Operation Guide 3490

Impact

•

Your watch is designed to withstand impact incurred during normal daily use and during light activity

such as playing catch, tennis, etc. Dropping your 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 engaging in strenuous sports activities (motocross, etc.)

Magnetism

•

Though operation of your watch normally is not affected by magnetism, its accuracy may be affected if

the watch itself becomes magnetized. Also, very strong magnetism (from medical equipment, etc.) should be avoided because it can cause malfunction of your watch and damage to electronic components.

Electrostatic Charge

•

Exposure to very strong electrostatic charge can cause your 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 your 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 resin case, resin band, leather, and other parts.

E-112

Leather Band

•

Allowing your 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 leather band to transfer to the other items or the color of the other items to transfer to the leather band. Be sure to dry off your watch thoroughly with a soft cloth 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.

CAUTION:

Metal Components

•

Bacteria and Odor Resistant Band

•

Exposing a leather band to rubbing or dirt can cause color transfer and discoloration.

Failure to clean dirt from metal components can lead to formation of rust, even if components are

stainless steel or plated. If metal components exposed to sweat or water, wipe thoroughly with a soft, absorbent cloth and then place the watch in a well-ventilated location to dry.

Use a soft toothbrush or similar tool to scrub the metal with a weak solution of water and a mild neutral

detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing metal components, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.

The bacteria and odor resistant band protects against odor generated by the formation of bacteria from

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

Storage

•

If you do not plan to use your watch for a long time, thoroughly wipe it free of all dirt, sweat, and

moisture, and store it in a cool, dry place.

Resin Components

•

Allowing your watch to remain in contact with other items or storing it together with other items for long

periods while it is wet can cause color on resin components to transfer to the other items, or the color of the other items to transfer to the resin components of your watch. Be sure to dry off your watch thoroughly before storing it and make sure it is not in contact with other items.

•

Leaving your watch where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to

clean dirt from your watch for long periods can cause it to become discolored.

•

Friction caused by certain conditions (strong 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.

•

Leaving your watch wet for long periods can cause fluorescent color to fade. Wipe the watch dry as

soon as possible after it becomes wet.

•

Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed to high

temperatures and humidity for long periods.

•

Daily use and long-term storage of your watch can lead to deterioration, breaking, or bending of resin

components. The extent of such damage depends on usage conditions and storage conditions.

Liquid Crystal Display

•

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

Watch with Data Memory

•

Allowing the battery to go dead, replacing the battery, or having your watch repaired can cause all data

in watch memory to be lost. Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damages or losses caused by data lost due to malfunction or repair of your watch, replacement of the battery, etc. Be sure to keep separate written copies of all important data.

Watch Sensors

•

A watch sensor is a precision instrument. Never try to take it apart. Never try to insert any objects into

the openings of a sensor, and take care to ensure that dirt, dust, or other foreign matter does not get into it. After using your watch where it has been immersed in saltwater, rinse it thoroughly with fresh water.

User Maintenance

Caring for Your Watch

Remember that you wear your watch next to your skin, just like a piece of clothing. To ensure your watch performs at the level for which it is designed, keep it clean by frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat, water and other foreign matter.

•

Whenever your watch is exposed to sea water or mud, rinse it off with clean fresh water.

•

For a metal band or a resin band with metal parts, use a soft toothbrush or similar tool to scrub the band

with a weak solution of water and a mild neutral detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing the band, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.

•

For a resin band, wash with water and then wipe dry with a soft cloth. Note that sometimes a smudge

like pattern may appear on the surface of a resin band. This will not have any effect on your skin or clothing. Wipe with a cloth to remove the smudge pattern.

•

Clean water and sweat from a leather band by wiping with a soft cloth.

•

Not operating a watch crown, buttons, or rotary bezel could lead to later problems with their operation.

Periodically rotate the crown and rotary bezel, and press buttons to maintain proper operation.

Dangers of Poor Watch Care

Rust

•

Though the metal steel used for your watch is highly rust-resistant, rust can form if your watch is not

cleaned after it becomes dirty.

− Dirt on your watch can make it impossible for oxygen to come into contact with the metal, which can lead to breakdown of the oxidization layer on the metal surface and the formation of rust.

E-116

E-115

•

Rust can cause sharp areas on metal components and can cause band pins to fly out of position or to

fall out. If you ever notice any abnormality immediately stop using your watch and take it to your original retailer or to an authorized CASIO service center.

•

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 bezel, or storing your watch an area subject to high moisture

can lead to premature wear, cuts, and breaks.

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. Should you ever experience a rash or other skin irritation, immediately remove your watch and contact a skin care professional.

Battery

•

The special rechargeable 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 your watch can damage your watch.

•

The rechargeable (secondary) battery is charged when the solar panel is exposed to light, so it does not

require regular replacement as the primary battery requires. Note, however, that long use or operating conditions can cause the capacity or charging efficiency of the rechargeable battery to deteriorate. If you feel that the amount of operation provided by charging is too short, contact your original retailer or CASIO service center.
