3.1 Initial Charging (Tough Solar)
Your Casio PRW6600Y watch is powered by Tough Solar technology, which converts light into electrical energy. Before initial use, ensure the watch is fully charged by exposing it to bright light for several hours. The power indicator on the digital display will show the current charge level.
- Place the watch where its face is exposed to bright light.
- Avoid covering the watch face with clothing while wearing it, as this can prevent charging.
- The watch features a Power Saving Function that automatically enters a sleep state when left in the dark to conserve energy.
3.2 Time Setting (Atomic Timekeeping - Multi Band 6)
The watch automatically receives time calibration signals from six transmission stations around the world (Multi Band 6) to maintain accurate time. Manual time adjustment is generally not required if signal reception is successful.
- Home City Setting: Ensure your Home City is correctly set. In Timekeeping Mode, hold down the 'Adjust' button (usually top-left) until the city code flashes. Use the 'Forward' and 'Reverse' buttons (usually right side) to select your desired city.

3.3 Calibració del sensor
For accurate readings from the altimeter, barometer, and compass, occasional calibration may be necessary.
- Altímetre: Calibrate the altimeter by inputting a known altitude value (e.g., from a map or sign) when you are at that location.
- Brúixola digital: Perform a bidirectional calibration to ensure accurate magnetic north readings. Follow the instructions in the full manual for the specific calibration procedure.
- Termòmetre: For accurate temperature readings, remove the watch from your wrist for at least 20-30 minutes to allow it to acclimate to ambient air temperature, as body heat can affect readings.
