Important Altimeter and Compass Information!

• 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 watch’s altimeter while mountain climbing, be sure to perform regular calibration in

accordance with the local altitude (elevation) indications. For more information, see “To specify a reference altitude value” (page E-56).

• 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.

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

When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.

• The watch may enter a sleep state

(page E-18) if its face is blocked by your sleeve even only partially.

Important!

• Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or

totally white, depending on the watch model). 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-18) 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

Hold down B for at least two seconds to enter the Timekeeping Mode. You can get an idea of the watch’s power level by observing the battery power indicator on the display.

Battery power indicator

• 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.

A dark environment while battery power is at Level 4 will cause the level to drop to Level 5. Expose the

watch to bright light whenever possible.

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 or off” (page

E-99).

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

Elapsed Time in Dark Hands and Display Operation

60 to 70 minutes (display sleep)

6 or 7 days (function sleep)

• 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.

• The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.

• The watch will not enter a sleep state while barometric pressure change indicator is enabled (page E-73).

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-36) 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:

LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainﬂ ingen (Germany)

HONG KONG (HKG) Shangqiu City (China)

TOKYO (TYO) Fukushima, Fukuoka/Saga (Japan)

Important!

• If the second hand does not point exactly at 12 o’clock after you perform step 4 above, perform the

operation under “Hand Home Position Adjustment” (page E-39) to adjust it.

• If the digital display contents start to ﬂ ash after you perform a reading operation, it means that

abnormal magnetism has been detected. Move away from any potential source of strong magnetism and try taking a reading again. If the problem occurs when you try again, continue to keep away from the source of strong magnetism, perform bidirectional calibration, and then try taking a reading again. For more information, refer to “To perform bidirectional calibration” (page E-47) and “Location” (page E-50).

Digital Compass Readings

• After the ﬁ rst reading is obtained, the watch will continue to take digital compass readings automatically

each second for up to 60 seconds. After that, the reading operation will stop automatically.

• The margin of error for the angle value and the direction indicator 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.

E-44

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.

• Any ongoing direction reading operation is paused temporarily while the watch is performing an alert

operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by pressing L). The direction reading operation resumes for its remaining duration after the operation that caused it to pause is ﬁ nished.

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 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°.

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 also 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 impossible while in a train, boat, air plane, etc.

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

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.

Digital Compass Precautions Magnetic North and True North

True north

Magnetic north

Earth

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.

Using the Altimeter Mode

The watch takes altitude readings and displays results based on air pressure measurements taken by a built-in pressure sensor. It also saves various types of altitude records and data.

• 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 watch’s altimeter while mountain climbing, it is recommended that you perform regular calibration in accordance with the local altitude (elevation) indications.

Important!

• See “To specify a reference altitude value” (page E-56) and “Altimeter Precautions” (page E-66) 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 reading interval.

Selecting the Altitude Auto Reading Interval

You can select either of the following two altitude auto reading interval.

0'05: Readings at one-second intervals for the ﬁ rst three minutes, and then every ﬁ ve seconds for

Taking Altitude Readings

Use the procedure below to take basic altitude readings.

• See “Using Reference Altitude Values” (page E-55) for information about how to make altimeter readings

more accurate.

• See “How does the altimeter work?” (page E-65) for information about how the watch measures altitude.

• The altitude tendency graph shows changes in altitude over the past 6 readings while readings are

being taken automatically.

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. During a trek, keep checking the readings produced by the watch against altitude information provided by markers and other information, and update the reference altitude value as required.

• Reading error can be caused by changes in barometric pressure, atmospheric conditions, and

elevation.

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

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.

Height of building 130 m (relative altitude)

Regular calibration of the watch in accordance with values provided by local altitude (elevation) indications is recommended before taking readings in order to maximize reading accuracy (page E-55).

Precautions Concerning Simultaneous Altitude and Temperature 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 temperature readings, keep the watch at as stable a temperature as possible. Changes in

temperature can affect temperature readings. See product speciﬁ information.

Important!

• To ensure proper results, take barometric readings under conditions where the altitude remains

constant.

Example

– In a lodge or campground – On the ocean

• A change in altitude causes a change in barometric pressure. Because of this, correct readings are

impossible. Do not take readings while ascending or descending a mountain, etc.

Barometric Pressure Change Indications

Your watch analyzes past barometric pressure readings and uses a barometric pressure change indicator to inform you about changes in pressure. If the watch detects a signiﬁ cant change in barometric pressure, it will beep and display a ﬂ ashing arrow that indicates the direction of the pressure change. This means you could start taking barometric pressure readings after reaching a lodge or camp area, and then check the watch the next morning for changes in pressure, and plan you day’s activities accordingly. Note that you can enable or disable display of the barometric pressure change indicator as desired. The barometric pressure change indicator is displayed in the Barometer Mode and while the barometric pressure graph is displayed in the Timekeeping Mode (page E-33).

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 and serious personal injury.

E-96

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.

E-98

• 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-95), 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.

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 watch’s altimeter while mountain climbing, you need to be sure to perform regular calibration in accordance with the local altitude (elevation) indications. For more information, see “To specify a reference altitude value” (page E-56).

Following a relative altitude reading, the watch’s second hand points to 9 o’clock.

Operation Guide 5578

• 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-112

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.

• Timekeeping 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.

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.

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.

• Leaving your 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).

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.)

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.

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

E-113

E-114

Metal Components

• 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.

Bacteria and Odor Resistant Band

• 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.

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.

E-116

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-115

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.

E-117

• 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.
