2. Setup
2.1 Initial Charge
Your Eco-Drive watch is powered by light. Before initial use, expose the watch face to bright light (natural sunlight or fluorescent lamp) for several hours to ensure it is sufficiently charged. Avoid placing it in direct sunlight for extended periods in hot environments to prevent damage.
2.2 Time and Date Adjustment (GPS Satellite Wave Reception)
The watch automatically receives GPS satellite signals to adjust time and date. For optimal reception, ensure the watch face is exposed to an open sky, away from buildings or electronic interference. Manual reception can also be initiated if needed.
- Automatic Reception: The watch attempts to receive signals at regular intervals.
- Manual Reception: Refer to the detailed instruction manual included in the box for specific button operations to initiate manual GPS signal reception.
2.3 Band Adjustment
The watch band is made of Super Titanium and features a fit adjuster. For precise sizing, it is recommended to have the band adjusted by a qualified jeweler or watch technician. Incorrect adjustment can lead to discomfort or damage to the band.
