Expose the device to light; the solar cell generates power and the rechargeable battery stores it. Charging time varies with light intensity, e.g., about 8 minutes in outdoor sunlight (50 000 lux).
Before setting time or date, follow the initial setup steps described in the manual, then use the function keys to select the city code and adjust the time and date.
Activate the automatic LED function via the designated function key; the LED will turn on automatically when ambient light falls below a set level.
