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.
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.
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).

Watch Operation Guide 3516

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 (GSHOCK, BABYG, GMS) 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 a digital watch normally is not affected by magnetism, very strong magnetism (from medical equipment, etc.) should be avoided because it can cause malfunction 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.
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.
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.

Watch Operation Guide 3516

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.
Heart Rate Monitor Functions
The back cover of the watch has a built-in sensor that detects your pulse. This is used to calculate and display an approximate heart rate value. The factors below can cause error in the displayed heart rate value. How the watch is affixed to the wrist Individual wrist characteristics and conditions Training type and intensity Sweat, dirt, and/or other foreign matter near the sensor
All of this means that heart rate values displayed by the watch are approximate, and no guarantees are made concerning their accuracy.
The heart rate monitor function of this watch is intended for recreational purposes, and should not be used in any way for medical purposes.

Chargeable Battery Handling (Please recycle!)
The built-in lithium-ion battery includes valuable resources. When you are ready to discard your watch, follow proper procedures in order to recycle resources. For information about the proper procedure to follow when discarding the watch, contact an authorized CASIO service center or your original retailer.
Important!
Do not try to replace batteries by yourself. Request battery replacement from an authorized CASIO service center or your original retailer.
Personal Information Protection Precautions
To protect your personal information, be sure to perform the operation under “Resetting Watch Settings” before transferring ownership of this watch to another party or before disposing of it.
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 your watch or its malfunction.

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.

Watch Operation Guide 3516

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.
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 can be charged by using the charging cable to connect the watch to a device equipped with a USB terminal, 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.
Regular, once-a-month charging is recommended to extend the service life of the watch’s battery.

Starting Heart-rate Training
With heart-rate training, you measure your heart rate and then use the resulting value as a benchmark for training. You can monitor your heart rate levels and keep your exercise intensity in line with your training goals, which contributes to more efficient training, improved cardiopulmonary function, and better health.

Heart Rate Zone (HR zones) Powered by Polar
To specify a target heart rate zone
Specify a target heart rate zone that matches your training objectives.
The range from 50% to 100% of your maximum heart rate is divided into five heart rate zones. You can easily control the intensity of your training by keeping your heart rate within a particular zone. Each heart rate zone has a main effect, and understanding these effects can enhance the effectiveness of your training.
Zone 1 (50 to 60% of maximum heart rate): Very light training Zone 1 training improves overall health and helps you recover from more strenuous training. You can continue training in this zone for long periods.
Zone 2 (60 to 70% of maximum heart rate): Light training Zone 2 training increases general stamina. It uses fat as an energy source, improving the body’s ability to burn fat. You can continue training comfortably in this zone for long periods.
Zone 3 (70 to 80% of maximum heart rate): Moderate training Zone 3 training improves aerobic fitness. It causes lactic acid to begin to accumulate in the bloodstream, but the body can reuse the lactic acid for energy, so it does not affect performance. Since Zone 3 training requires deeper breathing, you will feel the need for a moderate amount of effort.

Zone 4 (80 to 90% of maximum heart rate): Hard training Zone 4 training improves speed endurance and enhances the ability of the body to use protein (sugar) for energy. In addition, Zone 4 training allows you to tolerate high levels of lactic acid in the blood. Zone 4 training results in muscle fatigue and rough breathing.
Zone 5 (90 to 100% of maximum heart rate): Very hard training Zone 5 training improves maximum performance. Large amounts of lactic acid are accumulated, so long-term training is not possible. Zone 5 training results in labored breathing and muscle fatigue.

To set up the heart rate zone alert If you engage in heart-rate training while the heart rate zone alert is enabled, the watch will perform a sound and/or vibration operation to let you know when your current heart rate is outside your target zone. If you do not re-enter the target zone after the alert, an out-of-zone notification operation will be performed at oneminute intervals.

Activity Measurement Precautions

After using an activity function, use the charging cable to charge the watch. l Charging with the Charger Cable

Activity measurement is not possible while

the battery indicator shows

or lower.

Charging before performing an activity measurement is recommended. l Charging the Watch

If [MEMORY FULL] appears on the display while an activity measurement operation is in progress, the measurement operation stops. Measurement also stops automatically whenever a single activity measurement operation exceeds 80 hours.

You may not be able to save measurement results if the remaining activity log capacity is low. If this happens, delete log data you no longer need to make room for more data. l Deleting Activity Records

For information about the summary (Measurement Result) screen that appears after an activity measurement operation is complete, see the information below. l Viewable Activity Log Items

Watch Operation Guide 3516

Viewing Activity Log Records
After an activity measurement operation is completed, a summary (measurement results) is displayed and saved in watch memory as log data. There is enough memory to store up to 100 log records.
Measurement Data Accuracy The sensors of your watch calculate your
step count, calories burned, heart rate, running index (when phone GPS is used), and other data. No guarantees are made concerning the accuracy of the statistics and values calculated by this watch, so they should be used as general reference information only.

Heart Rate Measurement Precautions

Heart Rate Measurement Functions

The back cover of the watch has a built-in sensor that detects your pulse. This is used to calculate and display an approximate heart rate value. The factors below can cause error in the displayed heart rate value. How the watch is affixed to the wrist Individual wrist characteristics and condition Training type and/or intensity Sweat, dirt, and/or other foreign matter around the sensor

All of this means that heart rate values displayed by the watch are approximate, and no guarantees are made concerning their accuracy.

The conditions below may make accurate pulse detection impossible. Exercising in a low-temperature environment or under other conditions that reduce blood flow Arm tattoos Use of sunblock cream or lotion, insect repellent, etc.

The heart rate measurement function of this watch is intended for recreational purposes, and should not be used in any way for medical purposes.

Heart rate measurement is automatically disabled when the battery level indicator

shows

or lower.

Movements that Affect Heart Rate Measurement
Activities that involve vigorous movement of the arms only or other certain movements* may affect heart rate measurement and cause errors in the heart rate data displayed by the watch.

Activities involving vigorous wrist movements or wrist rolling such as playing a percussion instrument, tennis, etc.
Warming Up Before Training
Weak blood circulation due to low temperatures or cold hands may affect heart rate measurement.
When performing training that involves heart rate measurement, make sure to warm up appropriately.
Measurement while [ON] is selected for the heart rate measurement setting
While [ON] is selected for the heart rate measurement setting, your heart rate is measured intermittently (every two minutes). If the watch determines that you are performing some activity (based on behavior analysis by the acceleration sensor), heart rate measurement will be performed continuously (every second).

Blood Oxygen Level Measurement
Your watch can measure your blood oxygen level. A normal blood oxygen level is said to be 95% to 100%, but this varies depending on your activity level and physical condition.
Note
Note that values displayed by this watch are for reference only. Should you feel any abnormalities, consult with your doctor immediately.
Important!
Before starting a blood oxygen level operation, be sure to affix this watch to your wrist. Starting a measurement operation and then affixing the watch to your wrist may make correct measurement impossible.
The blood oxygen level measurement function is not intended as a medical device for diagnosing specific diseases. It is intended for general health maintenance only.

Watch Operation Guide 3516

Measuring Your Blood Oxygen Level
Important!
It may not be possible to obtain blood oxygen level measurement results if you are in a cold location and your wrist is cold. Warm your wrist before attempting measurement.
If measurement at the same location on your wrist fails continuously or if measured values fluctuate widely, change the location on your wrist where you are wearing the watch. You can also try moving the watch to your opposite wrist for measurement.
Take several measurements under identical conditions, moving the watch around your wrist. Find the wrist location where measurement is most stable.
Do not take measurements immediately after exercising. Wait until your breathing stabilizes.
During measurement, keep your arm still and do not move it.
During measurement, refrain from talking and do not hold your breath.
