Setup

1. Initial Charging (Tough Solar)

Your watch is equipped with a Tough Solar power system, which converts light into electrical energy to charge the built-in rechargeable battery. For optimal performance, ensure the watch is exposed to light regularly.

• Place the watch where its face is exposed to bright light (e.g., near a window).
• Avoid covering the watch face with clothing while wearing it.
• A full charge can provide approximately 6 months of operation with normal function use, or up to 20 months in power-saving mode.

2. Time Calibration (Multi-Band 6 Radio Reception)

The watch automatically receives standard radio waves from six global stations (Japan, China, North America, Europe) to ensure accurate timekeeping.

• The watch attempts automatic reception up to 6 times a day (5 times for Chinese radio waves).
• For best reception, place the watch near a window or in an open area at night.
• Manual reception is also possible. Refer to the detailed operation guide for instructions.
• If radio wave reception is not possible, the watch operates with standard quartz accuracy (average monthly difference of ±15 seconds).

Maintenance

1. Water Resistance (10 BAR)

This watch is rated for 10 BAR water resistance, making it suitable for daily use, showering, and swimming. However, it is not intended for scuba diving.

• Do not operate buttons while the watch is wet or submerged.
• Rinse the watch with fresh water after exposure to saltwater.

2. Power Saving Function

To conserve power, the watch automatically turns off its display when left in a dark place for a certain period. The timekeeping continues internally.

• The display will reactivate when exposed to light or when a button is pressed.
• Regular exposure to light is crucial for maintaining a sufficient charge.

Troubleshooting

1. Incorrect Time Display

• Check Radio Reception: Ensure the watch is in an area with good radio signal reception. Obstacles like buildings or being indoors can interfere. Try placing it near a window overnight.
• Manual Time Adjustment: If automatic reception fails consistently, you can manually adjust the time. Refer to the full user manual for detailed steps on manual time setting.

2. Watch Not Functioning / Display Blank

• Check Charge Level: The watch might be low on charge. Expose the watch face to bright light for several hours to charge it. The battery indicator (if visible) should show a higher level.
• Power Saving Mode: If the watch has been in a dark place, it might be in power-saving mode. Expose it to light or press any button to reactivate the display.

3. Buttons Not Responding

• Water Exposure: Ensure the watch is completely dry. Buttons should not be operated underwater or when wet.
• Reset: In rare cases, a full reset might be necessary. Consult the comprehensive user manual for instructions on performing a watch reset.
