How to use

Set the watch to your local time zone and enable radio reception to allow automatic synchronization with the regional time signal. The solar cell charges the internal battery during exposure to light; check the battery level indicator to confirm sufficient charge. Use the mode button to switch between timekeeping, world time, stopwatch, timer and alarm modes. Enable Full-Auto Illuminator to have the backlight activate only in low-light conditions, and switch button tones off if silent operation is preferred.

Usage recommendations

Avoid exposing the watch to strong magnetic fields and prolonged high temperatures. For reliable radio reception, place the watch near a window and avoid metal obstructions during signal reception. Regularly expose the watch to light to maintain battery charge and rinse with fresh water after prolonged saltwater exposure.
