Batterioplysninger
Your Casio MWA-300H watch is powered by 1 LR44 battery, which is included. The battery life is approximately 3 years. When the battery runs low, the watch may exhibit irregular movement or stop.

Operating: Watch Functions
Brug af kronografen (stopuret)
The chronograph function allows for precise timing of events. Your watch features a 1/10-second stopwatch that captures elapsed, split, and 1st/2nd place times across three dedicated sub-dials.
- Starting the Stopwatch: Press button A (typically the upper right button) to start the stopwatch.
- Stopping the Stopwatch: Press button A again to stop the stopwatch.
- Resetting the Stopwatch: After stopping, press button B (typically the lower right button) to reset the stopwatch hands to zero.
- Mellemtidsmåling: While the stopwatch is running, press button B to measure split times. The stopwatch hands will momentarily stop to indicate the split time, then resume timing. Press button B again to release the split time and display the current elapsed time.
Note: Refer to the specific button layout on your watch for exact button assignments.
Water Resistance (100 Meters)
Your Casio MWA-300H watch is water resistant up to 100 meters (330 feet). This rating means the watch is suitable for swimming, showering, and recreational water activities. It is not suitable for diving or snorkeling where significant water pressure changes occur.
- Do not operate the crown or buttons while the watch is wet or submerged.
- Efter udsættelse for saltvand, skyl uret med ferskvand og tør det af.
Lysende visere og markører
The watch features luminous hands and markers that absorb light and glow in the dark, providing readability in low-light conditions. The intensity and duration of the glow depend on the amount and type of light exposure.
Opretholdelse
Almen pleje
- Tør uret regelmæssigt af med en blød, tør klud for at fjerne snavs og fugt.
- Undgå at udsætte uret for ekstreme temperaturer, direkte sollys i længere perioder eller stærke magnetfelter.
- Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the resin materials.
Udskiftning af batteri
When the battery needs replacement, it is highly recommended to take your watch to an authorized Casio service center or a reputable watch repair shop. This ensures that the watch is properly sealed and its water resistance is maintained after battery replacement.
Vandtæthedskontroller
To maintain the water resistance of your watch, it is advisable to have it inspected periodically (e.g., every 2-3 years) by an authorized service center, especially if it is frequently exposed to water.
