Under Daily

Use

• Do not use this 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.

• 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.

• 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.

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.

• 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.

Impact

• Your watch is designed to withstand impact incurred during normal 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.

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.

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.

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.

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.

• 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.

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.

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.

• 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.

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 experience a rash or other

skin irritation, immediately remove the watch and contact a skin care professional.

Battery Replacement

• Leave battery replacement up to your original retailer or authorized CASIO Service

Center.

• Have the battery replaced only with the type specified by in this manual. Use of another

type of battery can cause malfunction.

• When replacing the battery, also request a check for proper water resistance. Note that

you will be charged separately for water resistance inspection.

Initial Battery

• The battery that comes loaded in your watch when you purchase it is used for function

and performance testing at the factory.

• This type of test battery may go dead quicker than the normally rated battery life as noted

in the User’s Guide. Note that you will be charged for replacement of this battery, even if

replacement is required within the watch’s warranty period.

Low Battery Power

• Low battery power is indicated by large timekeeping error, when display contents are

dim, or when the display does blank.

• Operation while battery power is low can result in malfunction. Replace the battery as

soon as possible.
