Asennus

Alkuajan asetus

1. Vedä kruunu ulos: Gently pull the crown (the knob on the side of the watch) out to the first click position.
2. Aseta aika: Rotate the crown to move the hour and minute hands to the desired time. Ensure AM/PM is correctly set if your watch has a 24-hour indicator or date changes at midnight.
3. Paina kruunu sisään: Once the time is set, push the crown back in to the normal position. The second hand will begin to move.

Päivämäärän asetus

The watch features a date window at the 3 o'clock position.

1. Vedä kruunu ulos: Vedä kruunu varovasti ulos ensimmäiseen napsautusasentoon.
2. Säädä päivämäärää: Rotate the crown in the opposite direction from time setting to change the date. Avoid setting the date between 9:00 PM and 1:00 AM, as this may interfere with the automatic date change mechanism.
3. Paina kruunu sisään: Työnnä kruunu takaisin normaaliasentoon.

Kellon käyttö

kellonaikatoimintoa

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.

Sekuntikellotoiminto

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.
• Jakoaika: 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.

Vedenkestävyys (100 m)

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.

• Varmista, että kruunu on työnnetty kokonaan sisään ennen kuin se joutuu kosketuksiin veden kanssa.
• Älä käytä kruunua tai painikkeita, kun kello on märkä tai uponnut veteen.
• Huuhtele kello suolavedellä ja pyyhi se kuivaksi, jos se on altistunut suolavedelle.

Valaiseva näyttö

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.

Huolto

Puhdistus

• 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.
• Vältä kemiallisten puhdistusaineiden, liuottimien tai hankaavien materiaalien käyttöä, sillä ne voivat vahingoittaa kellon pintaa.

Akun vaihto

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.

Vedenkestävyyttä koskevat varotoimet

• 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.

Vianetsintä

• Kello ei ole käynnissä: Tarkista, onko nuppi työnnetty kokonaan sisään. Jos näin on, paristo saattaa tarvita vaihtoa.
• Aika on epätarkka: Varmista, että nuppi on työnnetty kokonaan sisään. Jos aika on edelleen epätarkka, kello saattaa tarvita huoltoa.
• Päivämäärä ei muutu: 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.
