Sekundomer funktsiyasi

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.

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

Suvga chidamliligi (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.

  • Suv bilan aloqa qilishdan oldin tojning to'liq ichkariga bosilganligiga ishonch hosil qiling.
  • Soat ho'l yoki suv ostida bo'lganida tojni yoki tugmalarni ishlatmang.
  • Sho'r suvga ta'sir qilgandan so'ng, soatni toza suv bilan yuvib tashlang va uni quriting.

Yorqin displey

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.

Xizmat

Tozalash

  • Kir va namlikni tozalash uchun soat korpusi va tasmasini muntazam ravishda yumshoq, quruq mato bilan artib turing.
  • For resin bands, a mild soap solution and a soft brush can be used, followed by thorough rinsing and drying.
  • Kimyoviy tozalash vositalari, erituvchilar yoki abraziv materiallardan foydalanmang, chunki ular soatning qoplamasiga zarar etkazishi mumkin.

Batareyani almashtirish

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.

Suvga chidamlilik choralari

  • 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.

Muammolarni bartaraf qilish; nosozliklarni TUZATISH

  • Watch is not running: Toj to'liq ichkariga bosilganligini tekshiring. Agar shunday bo'lsa, batareyani almashtirish kerak bo'lishi mumkin.
  • Vaqt noto'g'ri: Soat tojining to'liq ichkariga bosilganligiga ishonch hosil qiling. Agar vaqt noto'g'ri bo'lishda davom etsa, unga texnik xizmat ko'rsatish kerak bo'lishi mumkin.
  • 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.
