Mengendalikan Jam Tangan

The watch displays hours, minutes, and seconds using analog hands. The quartz movement ensures accurate timekeeping with a precision of approximately ±20 seconds per month.

Fungsi Jam randik

The Casio MWA-300H-1AV includes a 1/10-second stopwatch for precise timing. This function is controlled by the two push-buttons located on either side of the crown.

• Starting the Stopwatch: Press the upper right button to start timing.
• Stopping the Stopwatch: Press the upper right button again to stop timing.
• Resetting the Stopwatch: While the stopwatch is stopped, press the lower right button to reset it to zero.
• Masa Pembahagian: Press the lower right button while the stopwatch is running to record a split time. Press it again to return to the current elapsed time.

The three sub-dials on the watch face indicate stopwatch minutes, seconds, and 1/10 seconds.

Rintangan Air (100M)

This watch is rated for 100-meter (330 feet) water resistance. This means it is suitable for swimming, showering, and recreational water activities. It is not suitable for scuba diving or high-impact water sports.

• Ensure the crown is fully pushed in before any contact with water.
• Do not operate the crown or push-buttons while the watch is wet or submerged.
• Selepas terdedah kepada air masin, bilas jam tangan dengan air tawar dan lap sehingga kering.

Paparan Bercahaya

The hour and minute hands, along with certain markers, are treated with a luminous material that absorbs light and glows in the dark, providing readability in low-light conditions.

Penyelenggaraan

Pembersihan

• Wipe the watch case and band with a soft, dry cloth regularly to remove dirt and moisture.
• For resin bands, a mild soap solution and a soft brush can be used, followed by thorough rinsing and drying.
• Elakkan menggunakan pembersih kimia, pelarut atau bahan kasar, kerana ini boleh merosakkan kemasan jam tangan.

Penggantian Bateri

The watch is powered by one SR920SW battery, which has an approximate lifespan of 3 years. When the watch stops or the second hand moves erratically, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.

Langkah Berjaga-jaga Ketahanan Air

• Have the water resistance gaskets checked and replaced every 2-3 years, especially if the watch is frequently exposed to water.
• Avoid exposing the watch to extreme temperature changes, which can affect the water resistance seals.

Menyelesaikan masalah

• Watch is not running: Periksa sama ada mahkota ditolak masuk sepenuhnya. Jika ya, bateri mungkin memerlukan penggantian.
• Masa tidak tepat: Ensure the crown is fully pushed in. If the time continues to be inaccurate, the watch may require servicing.
• Date does not change: Manually advance the date to ensure it is not stuck. If the issue persists, consult a service center.
• Fogging inside the crystal: This may indicate a loss of water resistance. Avoid further water exposure and have the watch inspected by a technician immediately.
