Important Information

Battery

If the display becomes dim or the backlight fails, replace the battery at a CASIO dealer. The battery included with your watch is for testing purposes and may have a shorter service life than standard batteries.

Water Protection

Watches are classified by water resistance levels (I to V) according to the degree of protection against water. Consult the table below to determine appropriate usage.

Notes:

• Watches are not waterproof. Avoid all moisture.
• Some water-resistant watches have leather straps. Do not wear them for swimming or other water activities where the strap may be submerged.

Watch Care

• Replace gaskets every 2-3 years to maintain water and dust resistance.
• If moisture enters the watch, have it checked by a CASIO dealer immediately.
• Avoid exposing the watch to extreme temperatures.
• Handle the watch with care and avoid dropping it.
• Do not overtighten the strap; a finger should fit comfortably between the strap and your wrist.
• Clean the watch and strap with a dry, soft cloth. A soft cloth dampened with a mild neutral detergent solution can also be used. Never use volatile agents such as benzine, solvents, or spray cleaners.
• Store the watch in a dry place when not in use.
• Avoid contact with benzine, cleaning solvents, spray aerosols, adhesives, paint, etc., as chemical reactions can damage gaskets, cases, and polish.
• Be cautious when cleaning straps with silk-screened designs to avoid damaging the graphics.

For watches with polymer straps:

• A white powdery substance on the strap is harmless and can be easily removed by wiping with a soft cloth.
• Sweat or moisture, and high humidity can damage or crack polymer straps. To ensure a long service life, wipe the strap clean frequently.

For watches with fluorescent cases and straps:

• Prolonged exposure to direct sunlight may cause fluorescent colors to fade.
• Prolonged contact with moisture can cause fluorescent colors to fade. Wipe off any moisture promptly.
• Contact with damp surfaces may lead to discoloration of fluorescent colors. Keep surfaces dry.

General Warning:

• Never press buttons underwater.
• Never adjust hands underwater.
• Never unscrew the crown underwater.
• If exposed to saltwater, rinse thoroughly and dry.
• If exposed to saltwater, rinse thoroughly and dry.
• The watch can be used for scuba diving (except for depths requiring a helium-oxygen mixture).

Calibration Signal

This watch automatically calibrates its time based on a time signal. You can also manually set the time.

Signal Transmission Centers: Located in Germany (25km from Frankfurt) and Antorn, England. The signal range is approximately 1500km. Signals may be weak beyond 500km.

Factors Affecting Signal Reception: Signal reception depends on weather conditions, atmospheric pressure, and temperature. Factors that can weaken the signal include:

• Being near televisions, computers, or home appliances.
• Being in subways, tunnels, or near airports, train stations, or high-speed roads.
• Being near radio transmitters or stations.
• Experiencing static electricity.

Calibration Signal Reception Types:

• Auto-Calibration: When enabled, the watch automatically receives the signal six times daily to adjust the time.
• Forced Calibration: You manually initiate the signal reception.

To perform Forced Calibration:

1. Place your watch horizontally.
2. In Current Time Mode, press and hold [button D] for two seconds until the "RC" indicator flashes, indicating the watch is ready for calibration.
3. The second hand will move to the 12 o'clock position and stop.
4. The calibration process takes 2 to 7 minutes, sometimes up to 14 minutes. Do not move the watch during this period.
5. After reception, if successful, the last reception data will be displayed.
6. To stop the calibration process and return to Current Time Mode, press [button D].
7. If reception fails, the "ERR" indicator will appear, and the watch will automatically return to Current Time Mode. You can also press [button D] to return to Current Time Mode.
