Setup

Initial Charging

Your G-Shock watch is equipped with Tough Solar technology, which converts light into electrical power. Before initial use, expose the watch face to bright light for several hours to ensure a full charge. The battery level indicator (L, M, H) on the display will show the current charge status.

Automatic Time Synchronization (Multi Band 6)

The GW-M5610U-1ER features Multi Band 6 technology, allowing it to receive time calibration signals from six transmission stations around the world. This ensures highly accurate timekeeping. The 'RCVD' indicator on the display confirms successful signal reception.

• For optimal reception, place the watch near a window at night.
• The watch typically attempts to receive a signal automatically between midnight and 5:00 AM.

Manual Time Setting

If automatic reception is unavailable or you need to adjust settings manually:

1. Press and hold the Adjust button (top left) until the city code starts flashing.
2. Use the Set (+) and Set (-) buttons (right side) to select your home city code.
3. Press the Mode button (bottom left) to cycle through settings like DST (Daylight Saving Time), 12/24-hour format, seconds, hour, minute, year, month, and day.
4. Use the Set (+) and Set (-) buttons to change the flashing values.
5. Press the Adjust button to exit the setting mode.

Operating Modes

Press the Mode button (bottom left) to cycle through the different operating modes:

• Timekeeping Mode: Displays current time, day of the week, and date.
• World Time (WT) Mode: Allows you to view the current time in various major cities around the world. Use the Set (+) and Set (-) buttons to scroll through city codes.
• Alarm (AL) Mode: Set up to 5 daily alarms and a snooze alarm. The 'P' indicator next to the time signifies PM.
• Stopwatch (ST) Mode: Measures elapsed time. Press the Set (+) button to start/stop, and the Set (-) button to reset.
• Countdown Timer (TR) Mode: Functions as a countdown timer. Set the desired time using the Adjust and Set buttons, then press Set (+) to start.

Backlight (Illuminator)

The watch features an LED backlight for visibility in low light conditions.

• Press the Light button (top right) to manually activate the backlight.
• The watch also has an auto-light feature that illuminates the display when you tilt your wrist towards your face in dim lighting. This feature automatically deactivates in bright environments to conserve power.

Maintenance

Charging

To maintain optimal battery performance, regularly expose your watch to light. The battery level indicator (L, M, H) shows the charge level. Aim to keep it at 'H' (High) for best functionality.

Water Resistance (20 BAR)

Your G-Shock GW-M5610U-1ER is rated for 20 BAR (200 meters) water resistance. This means it is suitable for everyday use, swimming, snorkeling, and even scuba diving (non-saturation diving). Always ensure buttons are not operated while the watch is wet or submerged.

General Care

Clean your watch regularly with a soft, dry cloth. For stubborn dirt, use a soft brush and mild soap solution, then rinse thoroughly with fresh water and dry. Avoid exposing the watch to extreme temperatures or harsh chemicals.

Troubleshooting

Time Synchronization Issues

If your watch is not receiving the time calibration signal:

• Ensure the watch is placed in an area with good signal reception, ideally near a window, away from electronic devices that may cause interference.
• Check the 'RCVD' indicator. If it's not displayed, the last reception attempt may have failed.
• Manually initiate a reception attempt by holding the Set (+) button in Timekeeping Mode until 'RCVD' flashes.

Low Battery Indicator ('L')

If the battery level drops to 'L' (Low), some functions may be disabled. Expose the watch to bright light immediately to recharge. If the battery level reaches 'CHG' (Charge), all functions will stop, and the watch will require significant light exposure to resume operation.
