CASIO Module No. 3290

IMPORTANT INFORMATION

Battery

The battery installed at the factory may discharge during delivery and storage. If you notice signs of insufficient power (e.g., dim display), replace the battery at an authorized CASIO service center or a CASIO dealer.

Water Resistance

The following actions are prohibited for all categories of watches:

• Pressing buttons underwater.
• Adjusting hands underwater.
• Unscrewing the crown underwater.

If the watch is exposed to salt water, rinse it thoroughly with fresh water and dry it. Do not wear a watch with a leather strap while swimming. Avoid prolonged contact of leather straps with water.

Water Resistance Classification

Watches are classified into levels (I to V) according to their water resistance. Check your watch's level using the table below to determine its proper use.

Notes:

• Level I: Watches are not water resistant. Avoid exposure to any moisture.

Water Resistance Explanations

Level II WR (Water Resistant): Indicates water resistance according to ISO 2281. Brief contact with water will not cause problems.

Level III 5 Bar (50 meters): Watches can withstand water pressure of the indicated level and can be used while showering and for brief swimming.

Level IV 10 Bar (100 meters): Watches can be used for normal swimming and snorkeling.

Level V 20 Bar (200 meters): Watches can be used for scuba diving (excluding depths requiring helium-oxygen mixtures).

Care for Your Watch

• Never attempt to open the case or remove the back cover yourself.
• The rubber gasket that protects the watch from water and dust should be replaced every 2-3 years.
• If moisture gets inside the watch, have it checked immediately by your dealer or a CASIO distributor.
• Do not expose the watch to extreme temperatures.
• Although designed for active daily use, wear the watch carefully and avoid drops.
• Do not fasten the strap too tightly. You should be able to fit a finger between your wrist and the strap.
• To clean the watch and strap, use a dry soft cloth or a soft cloth dampened with a mild neutral detergent solution. Never use volatile agents (e.g., gasoline, solvents, spray cleaners, etc.).
• When not using your watch, store it in a dry place.
• Avoid exposure to gasoline, cleaning solvents, aerosol sprays, adhesives, paint, etc. Chemical reactions from these materials can damage gaskets, the case, and the watch's finish.
• Some models feature silk-screened designs on the strap. Be careful when cleaning these straps to avoid damaging the designs.

For Watches with Plastic Straps

• You may notice a white powdery substance on the strap. This substance is harmless to skin or clothing and can be easily removed by wiping with a cloth.
• Exposure to sweat or moisture, or storage in high humidity, can damage, tear, or crack plastic straps. To ensure a long service life, wipe the strap clean of dirt and water with a soft cloth whenever possible.

For Watches with Fluorescent Cases and Straps

• Prolonged exposure to direct sunlight can cause fluorescent colors to fade gradually.
• Prolonged contact with moisture can cause fluorescent colors to fade gradually. If moisture gets on the watch surface, wipe it off as soon as possible.
• Prolonged contact with any other wet surface can cause fluorescent colors to discolor. Check that the fluorescent surface is dry and avoid contact with other surfaces.
• Strong friction of a surface with fluorescent paint against another surface may transfer the fluorescent paint.

In conditions of rapid temperature changes, slight condensation may form on the inside of the glass. This phenomenon is due to physical laws and is not a defect.

CASIO COMPUTER CO., LTD. is not responsible for any damage that may occur during the use of this watch and does not accept claims from third parties.

BACKLIGHT

An electroluminescent panel is used for the backlight, making it easier to read the time in the dark.

Precautions for Using the Backlight

• The electroluminescent panel, which provides the backlight, gradually loses its power over time.
• The backlight is difficult to see in direct sunlight.
• The watch may emit a faint clicking sound when the backlight is turned on. This is due to vibration of the electroluminescent panel and does not indicate a malfunction.
• The backlight automatically turns off when any alarm sounds.
• Frequent use of the backlight shortens battery life.

Turning On the Backlight

• In any mode, press button B to turn on the screen backlight.
• You can set the backlight duration to 1.5 or 3 seconds.

Setting Backlight Duration

1. In Current Time Mode, press and hold button A until the seconds digits start flashing. This indicates you have entered backlight duration setting mode.
2. Press button B to set the backlight duration to 3 seconds (display shows indicator ?) or 1.5 seconds (display shows indicator ∷).
3. Press button A to exit setting mode.

REFERENCE INFORMATION

Sound Signal When Pressing Buttons

A sound signal is emitted when a button is pressed. You can turn this sound ON or OFF.

• Even if the button press sound is turned OFF, other signals (hourly chime, alarms, stopwatch, countdown timer) will sound according to their settings.

Turning Button Sound ON and OFF

In any mode (except parameter setting mode), press and hold button C to turn the button sound ON (indicator ? is not displayed) or OFF (indicator ? is displayed).

The indicator ? is displayed on the screen in all modes when the button sound is OFF.

Auto-Return

• If you do not perform any operations for 2-3 minutes while setting the watch, it will automatically exit setting mode. Any settings made will be saved.
• If you do not perform any operations for 2-3 minutes in Alarm Mode, the watch will automatically return to Current Time Mode.

Accelerated Parameter View

Using buttons B and D, you can quickly scroll through settable data during parameter adjustment. Holding down one of the buttons will result in accelerated scrolling.

Initial Screens

When entering World Time Mode or Alarm Mode, the screen will display the data you were viewing before exiting that mode.

World Time

The time displayed in World Time Mode is synchronized with the time in Current Time Mode and is displayed taking into account the difference from UTC.

• Seconds in World Time Mode are synchronized with seconds in Current Time Mode.
• Difference from UTC: This value indicates the difference between the prime meridian (Greenwich, England) and your city's time zone.
• The letters "UTC" mean "Coordinated Universal Time", a global scientific standard for time measurement. It is based on highly accurate atomic (cesium) clocks that measure time with microsecond precision. Correction seconds are added or subtracted as needed to synchronize Coordinated Universal Time with the Earth's rotation.
