Setup
Initial Charge
Before first use, expose the watch face to light for several hours to ensure a full charge. This watch utilizes a solar charging system, converting light from sources like sunlight or fluorescent lamps into power.

The Multiband 6 feature automatically corrects time by receiving standard radio waves from 6 global stations (Japan, China, USA, Europe). The Tough Solar system powers the watch using light, reducing the need for battery replacement.
Time Calibration (Multiband 6)
The watch automatically receives time calibration signals. For optimal reception, place the watch near a window at night. The Multiband 6 feature ensures accurate timekeeping by synchronizing with atomic clocks in Japan, China, the United States, and Europe.
If automatic reception is not successful, manual time adjustment may be required. Refer to the detailed English PDF manual for specific instructions on manual time setting and signal reception.
