Setup

Initial Charge (Tough Solar)

Your Casio Edifice watch is equipped with Tough Solar power, which converts light into energy. Before initial use, expose the watch to bright light (natural sunlight is ideal) for several hours to ensure it is sufficiently charged. Avoid placing the watch in direct sunlight for prolonged periods in extremely hot environments to prevent damage.

Mobile Link (Bluetooth) Setup

The Mobile Link feature allows your watch to connect with a smartphone via Bluetooth for automatic time adjustment, world time settings, and other functions. To set up:

1. Download the official Casio EDIFICE Connected app from your smartphone's app store.
2. Enable Bluetooth on your smartphone.
3. On the watch, press and hold the 'CONNECT' button (usually located at the 4 o'clock position) until the Bluetooth indicator appears on the digital display.
4. Follow the on-screen instructions in the EDIFICE Connected app to pair your watch. Ensure your watch is close to your smartphone during the pairing process.

Time and Date Adjustment

Once connected via Mobile Link, your watch will automatically synchronize its time and date with your smartphone. Manual adjustments can also be made using the crown and buttons as detailed in the full instruction manual provided with your watch.

Band Adjustment

The stainless steel bracelet can be adjusted to fit your wrist. It is recommended to have this adjustment performed by a professional jeweler or watch technician to prevent damage to the band or clasp mechanism.

Chronograph Function (Stopwatch)

To use the chronograph:

1. Enter the Stopwatch mode using the 'MODE' button.
2. Press the 'START/LAP' button (usually at the 2 o'clock position) to start the stopwatch.
3. Press 'START/LAP' again to record lap times or stop the measurement.
4. Press the 'RESET' button (often shared with 'ADJUST' or 'LIGHT') to reset the stopwatch to zero.

Countdown Timer

The countdown timer can be set for specific durations. Once the timer reaches zero, an alarm will sound. Refer to the full manual for detailed setting instructions.

Alarms

The watch supports multiple daily alarms. These can be set and managed either directly on the watch or more conveniently through the EDIFICE Connected app.

World Time

View the current time in various major cities around the world. This feature is easily managed via the Mobile Link function, allowing you to select cities from a comprehensive list.

Double LED Light

Press the 'LIGHT' button (typically at the 6 o'clock position) to illuminate both the analog dial and the digital display for visibility in low-light conditions.

Tachymeter Scale

The tachymeter scale on the bezel can be used in conjunction with the chronograph to measure speed over a known distance (e.g., average speed of a vehicle over a 1-kilometer or 1-mile course).

Maintenance

Cleaning

Regularly wipe the watch case and band with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or abrasive materials.

Water Resistance

This watch is rated for 100M (10 BAR) water resistance. This means it is suitable for everyday use, showering, swimming, and snorkeling. Do not operate the crown or buttons while the watch is wet or submerged. Avoid exposure to hot water or steam, as this can compromise the water resistance seals.

Tough Solar Power Care

To maintain optimal charge, ensure the watch is regularly exposed to light. When not in use, store it in a location where it can receive light, rather than in a dark drawer. If the watch's charge level drops too low, some functions may be disabled to conserve power.

Storage

When storing the watch for extended periods, ensure it is fully charged. Store it in a cool, dry place away from extreme temperatures, direct sunlight, and strong magnetic fields.

Troubleshooting

Watch Not Charging / Low Power

• Ensure the watch dial is exposed to bright light for several hours.
• Check the charge indicator on the digital display (if available).
• Avoid covering the dial, as this prevents light absorption.

Time Not Syncing with Smartphone

• Verify Bluetooth is enabled on your smartphone and the watch.
• Ensure the EDIFICE Connected app is running and updated.
• Bring the watch and smartphone closer together.
• Restart both the watch's Bluetooth connection and the smartphone's Bluetooth.
• If issues persist, try unpairing and re-pairing the watch with the app.

Buttons Not Responding

• Check if the watch is in a specific mode that restricts button operation (e.g., power-saving mode).
• Ensure the watch is sufficiently charged.
• If the watch has been exposed to water, ensure it is completely dry before operating buttons.

For more complex issues or repairs, please contact Casio customer support or an authorized service center. Do not attempt to open or repair the watch yourself, as this may void the warranty.
