Setup
1. Initial Time Setting (Atomic Timekeeping)
Your watch is equipped with Multi Band 6 atomic timekeeping, which automatically receives time calibration signals from six transmission stations around the world. This ensures accurate time display.
- Ensure the watch is exposed to an open area, away from metal objects or electronic devices that may interfere with signal reception.
- The watch will attempt to receive the calibration signal automatically between midnight and 5:00 AM daily.
- To manually initiate reception, refer to the "Time Calibration Signal Reception" section in the detailed module manual (available on the Casio website).
2. Manual Time and Date Setting
If atomic timekeeping is not available or desired, you can set the time and date manually.
- In the Timekeeping Mode, press and hold the ADJUST button (usually top-left) until the city code starts flashing.
- Use the MODE button (usually bottom-left) to cycle through settings: City Code, DST (Daylight Saving Time), 12/24-hour format, Seconds, Hour, Minute, Year, Month, Day.
- Use the SEARCH and REVERSE buttons (usually top-right and bottom-right) to change the flashing values.
- Once all settings are correct, press the ADJUST button again to exit the setting mode.
3. World Time Setup
The watch can display the current time in 29 different time zones (48 cities).
- Enter the World Time Mode by pressing the MODE button.
- Use the SEARCH and REVERSE buttons to scroll through the available city codes.
- To toggle Daylight Saving Time (DST) for a specific city, press the ADJUST button while the city code is displayed.
Operating the Watch
1. Mode Navigation
Press the MODE button (bottom-left) to cycle through the different modes:
- Timekeeping Mode: Displays current time, date, and day of the week.
- World Time Mode: Displays current time in various cities around the globe.
- Alarm Mode: Set up to 5 daily alarms and an hourly time signal.
- Stopwatch Mode: Measures elapsed time, split times, and two finishes.
- Timer Mode: Countdown timer with a range of 1 minute to 24 hours.
2. Using the Illuminator
The watch features an Illuminator for visibility in low-light conditions.
- Press the LIGHT button (usually top-right or front center) to illuminate the display.
- The illumination duration can be adjusted in the settings.
3. Water Resistance (200M)
Your watch is water resistant to 200 meters (20 BAR), making it suitable for swimming, showering, and snorkeling.
- Do not operate buttons while the watch is wet or submerged.
- Avoid exposing the watch to hot water or steam, as this can compromise the water resistance seals.
- After exposure to saltwater, rinse the watch with fresh water and wipe it dry.
Maintenance
1. Cleaning Your Watch
Regular cleaning helps maintain the appearance and longevity of your watch.
- Wipe the watch case and band with a soft, dry cloth.
- For resin bands, you can use a mild soap solution and a soft brush, then rinse thoroughly with water and dry.
- Avoid using harsh chemicals or abrasive cleaners.
2. Battery Replacement
The watch is powered by a battery. When the display becomes dim or the watch stops functioning, it may be time for a battery replacement.
- Battery replacement should ideally be performed by an authorized Casio service center to ensure proper sealing and water resistance.
- Attempting to replace the battery yourself may void the warranty and compromise the watch's water resistance.
Troubleshooting
- Time is incorrect or not syncing:
Ensure the watch is in an area with good signal reception, away from strong magnetic fields or electronic interference. Verify your home city setting is correct. If automatic reception fails, try manual time setting.
- Display is dim or blank:
This may indicate a low battery. Contact an authorized service center for battery replacement.
- Buttons are unresponsive:
Ensure the watch is not in a locked mode (if applicable, refer to the full module manual). If the watch was recently exposed to water, ensure it is completely dry. If the issue persists, seek professional service.
