Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully and keep it on hand for later reference when necessary.
Important!
The fishing level indicator and moon phase indicator produced by this watch are all based on calculations that use the watch’s current time, date, and HomeSite settings.  Because of this, you should make sure that the current date and time, and your Home Site data are all correct before using the indicators. When fishing, always take proper precautions to ensure your own personal safety and the personal safety of others around you.
Note that the fishing level indicator and moon phase indicator are all based on calculated values. They are provided only for reference purposes.
See the “Timekeeping” section of this manual for information about setting the current time and date, and about specifying your Home Site.

About This Manual

• Button operations are indicated using the letters shown in the illustration.
• For the sake of simplicity, the sample displays in this manual do not show the analog hands of the watch.

Home Site Data

Moon phase, the fishing level indicator, and Fishing/Moon Mode data will not be displayed properly unless Home Site data (UTC differential and longitude) is configured correctly.

• The UTC differential is a value that indicates the time difference between a reference point in Greenwich, England, and the time zone where a city is located.

• The letter “UTC” is the abbreviation for “Coordinated Universal Time”, which is the worldwide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.

• The “Site Data List” at the back of this manual provides UTC differential, latitude, and longitude information around the world.

• The following is the initial factory default Home Site data (Tokyo, Japan) when you first purchase the watch, and whenever you have the battery replaced.
  Change these settings to match the area where you normally use the watch.

• UTC differential (+9.0); Longitude (East 140 degrees)

Reference

This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and functions of this watch.
Moon Phase Indicator
The Moon phase indicator of this watch indicates the current phase of the Moon as shown below.

• The Moon phase indicator shows the Moon as viewed at noon from a position in the Northern Hemisphere looking south. Note that at times the image shown by the Moon phase indicator may differ from that of the actual Moon in your area.
• The left-right orientation of the Moon phase is reversed when viewing from the Southern Hemisphere or from a point near the equator.

Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon appears to wax and wane as the relative positioning of the Earth, Moon, and Sun changes. The greater the angular distance between the Moon and the Sun,* the more we see illuminated.

• The angle to the Moon in relation to the direction at which the Sun is visible from the Earth.
  This watch performs a rough calculation of the current Moon age starting from day 0 of the moon age cycle. Since this watch performs calculations using integer values only (no fractions), the margin for error of the displayed Moon age is ±1 day.

Button Operation Tone

The button operation tone sounds any time you press one of the watch’s buttons. You can turn the button operation tone on or off as desired.
The multi-function alarms and Countdown Timer Mode alarm will sound even if the button operation tone is turned off.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the display), hold down C to toggle the button operation tone on ( not displayed)  and off ( displayed).

• Holding down C to turn the button operation tone on or off also causes the watch’s current mode to change.
• The indicator is displayed in all modes when the button operation tone is turned off.

Auto Return Features

• If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch automatically exits the setting screen.
• If you leave the watch in the Fishing/Moon Mode, Alarm Mode, and Hand setting Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode.

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

Timekeeping

• Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month lengths and leaps years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced.

Illumination Precautions

• Illumination may be hard to see when viewed under direct sunlight.
• Illumination automatically turns off whenever an alarm sounds.
• Frequent use of illumination runs down the battery.

Operating Precautions

Water Resistance

• The information below applies to watches with WATER RESIST or WATER RESISTANT marked on the back cover.
  | Water Resistance Under Daily Use| Enhanced Water Resistance Under Daily Use
  ---|---|---
  5
  Atmospheres| 10
  Atmospheres| 20
  Atmospheres
  Marking| On watch front or on back cover| No
  BAR mark| 5BAR| 10BAR| 20BAR
  Example of Daily Use| Hand washing, rain| Yes| Yes| Yes| Yes
  Water-related work, swimming| No| Yes| Yes| Yes
  Windsurfing| No| No| Yes| Yes
  Skin diving| No| No| Yes| Yes

• 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 submerged 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).

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.)

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.
• 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 a very strong electrostatic charge can cause your watch to display the wrong time. A 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 the 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 the 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 the formation of rust, even if components are stainless steel or plated. If metal components are 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 suppress the formation of organisms and bacteria. It does not protect against rash due to allergic reactions, etc.

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 seawater 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 the 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 skincare 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 in the User’s Guide. The use of a different battery type can cause malfunction.
• When replacing the battery, also request a check for proper water resistance.
• Ornamental resin components may become worn, cracked, or bent over time when subjected to normal daily use. Note that if cracking or any other abnormality indicating possible damage is noticed in a watch submitted for battery replacement, your watch will be returned with an explanation of the abnormality, without the requested servicing being performed.

Initial Battery

• The battery that comes loaded in your watch when you purchase it is used for function and performance testing at the factory.
• The 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 the replacement of this battery, even if replacement is required within your watch’s warranty period.

Low Battery Power

• Low battery power is indicated by large timekeeping error, by dim display contents, or by a blank display.
• The operation, while battery power is low, can result in malfunction. Replace the battery as soon as possible.
