Setup

Before using your watch, ensure it is sufficiently charged and set to your local time zone.

1. Initial Charging

Your G-Shock watch is equipped with Tough Solar power. Expose the watch face to light (natural sunlight or fluorescent light) to charge the built-in rechargeable battery. A full charge can last approximately 10 months without further exposure to light, assuming normal use and no power-saving features.

• Place the watch where it can receive direct light.
• Avoid placing the watch in extremely hot environments during charging.
• The battery indicator (L, M, H) on the display will show the current charge level. Aim for 'H' (High).

2. Setting Your Home City and Time Zone

The correct home city setting is crucial for accurate time calibration signal reception and World Time functionality.

1. In the Timekeeping Mode, hold down the ADJUST button (top left) until the city code starts to flash. This indicates the setting mode.
2. Use the SET (+) button (top right) and SET (-) button (bottom right) to select your desired home city code. Refer to the world time city code list in the full manual for your specific city.
3. Press the MODE button (bottom left) to cycle through other settings like DST (Daylight Saving Time) and 12/24-hour format. Adjust these using the SET (+) and SET (-) buttons.
4. Once all settings are configured, press the ADJUST button to exit the setting mode.

3. Receiving Time Calibration Signals (Multi-Band 6)

Your watch automatically attempts to receive the time calibration signal up to six times a day (five times for the Chinese calibration signal). For best reception, place the watch near a window at night.

• Ensure your home city is correctly set to a city within the reception range of one of the six transmitters.
• The "RCVD" indicator on the display will appear when a successful reception occurs.
• You can manually initiate reception by holding down the SET (+) button in Timekeeping Mode until "RCVD" starts flashing.

Operating Your Watch

The GW-M5610-1BJF has four buttons: ADJUST (top left), MODE (bottom left), SET (+) (top right), and SET (-) (bottom right).

1. Navigating Modes

Press the MODE button to cycle through the different watch modes:

1. Timekeeping Mode (current time, date)
2. World Time Mode (time in other cities)
3. Alarm Mode (set and activate alarms)
4. Stopwatch Mode (measure elapsed time)
5. Countdown Timer Mode (set a countdown)

2. Using the EL Backlight

Press the EL BACK LIGHT button (top right, often labeled "LIGHT" or "EL") to illuminate the display for a few seconds. The watch also features an auto-light function that illuminates the display when you tilt your wrist towards your face in dim conditions.

3. Power Saving Function

To conserve power, the watch display will go blank if left in the dark for a certain period. The timekeeping continues internally. To reactivate the display, expose the watch to light or press any button.

Maintenance

Proper care will extend the life and maintain the appearance of your G-Shock watch.

1. Charging and Battery Life

Regular exposure to light is essential for maintaining the watch's charge. Avoid prolonged storage in dark places. The battery indicator (L, M, H) will show the current charge level. If the indicator drops to 'L', ensure the watch receives sufficient light.

• Approximate battery life on full charge without further light exposure: 10 months.
• With power-saving function enabled, this can extend to approximately 26 months.

2. Cleaning Your Watch

Wipe the watch regularly with a soft, dry cloth. If the watch is exposed to saltwater or dirt, rinse it with fresh water and then dry it thoroughly. Do not use chemical cleaners or solvents.

3. Water Resistance

Your watch is rated for 20 BAR (200 meters) water resistance. This means it is suitable for everyday use, swimming, snorkeling, and skin diving. Do not operate buttons while the watch is submerged in water.

Troubleshooting

If you encounter issues with your watch, try the following solutions before seeking professional service.

1. Time is Incorrect or Not Syncing

• Check Home City Setting: Ensure your home city is correctly set to a city within the reception range.
• Signal Reception: Place the watch near a window overnight or manually initiate reception. Avoid placing it near electronic devices that emit strong signals.
• Charge Level: A low battery charge can affect signal reception. Ensure the battery indicator is at 'M' or 'H'.

2. Display is Dim or Blank

• Charge Level: The battery might be low. Expose the watch to bright light for several hours.
• Power Saving Mode: The watch might be in power-saving mode. Expose it to light or press any button to reactivate the display.

3. Buttons Not Responding

• Reset: In rare cases, a full reset might be needed. Consult the full Casio manual for your specific module number (usually found on the watch's back case) for detailed reset procedures.
• Water: Ensure the watch is completely dry if it was recently exposed to water.
