Initial Charging (Tough Solar)
Your PRO TREK watch is equipped with Tough Solar technology, converting light into energy to power the watch. For initial setup or after prolonged storage, ensure the watch is exposed to bright light for several hours to achieve a full charge. Avoid covering the watch face when charging.
- Place the watch in a location where it can receive direct sunlight or strong fluorescent light.
- Avoid placing the watch in extremely hot environments during charging.
- A fully charged watch can operate for approximately 6 months without further light exposure under normal use, or up to 25 months in power-saving mode.
Axuste da hora e da data
The watch automatically adjusts time and date based on its internal calendar. Manual adjustments may be necessary for specific time zones or if the watch has been without power for an extended period.
- Pull out the crown to the first click. The second hand will move to the current time zone city code.
- Rotate the crown to select your desired city code. The digital display will show the time for that city.
- Push the crown back in to set the time zone.
- For manual time adjustment, pull the crown out to the second click. The second hand will move to 12 o'clock.
- Use the buttons (usually A, B, C, D) to adjust hours, minutes, and date as indicated in the digital display. Refer to the specific button functions printed on the watch bezel or case for precise control.
- Push the crown back in to finalize the settings.

Funcións operativas
The PRO TREK PRG-650Y-1CR features a Triple Sensor for environmental data and various timekeeping modes.
Triple Sensor Functions
Access these functions using the dedicated sensor buttons, typically labeled ALTI (Altimeter), BARO (Barometer), and COMP (Compass).
- Altímetro: Measures current altitude based on atmospheric pressure. Press the ALTI button to activate. The digital display will show the altitude.
- Barómetro: Displays atmospheric pressure, which can indicate weather trends. Press the BARO button to activate. The digital display will show the barometric pressure.
- Termómetro: Measures ambient temperature. For accurate readings, remove the watch from your wrist for at least 20-30 minutes to avoid body heat interference.
- Compás dixital: Determines magnetic north and displays bearing. Press the COMP button to activate. The second hand will point north, and the digital display will show the bearing in degrees.

Mantemento
Limpeza
Unha limpeza regular axuda a manter a aparencia e a funcionalidade do teu reloxo.
- Wipe the watch with a soft, dry cloth to remove dirt and moisture.
- For stubborn dirt, use a soft brush and mild soap solution, then rinse thoroughly with fresh water and dry completely.
- Avoid using harsh chemicals or abrasive materials, as they can damage the watch's finish or seals.
Resistencia á auga
The PRG-650Y-1CR is water-resistant up to 100 meters (10 BAR). This means it is suitable for swimming and snorkeling, but not for scuba diving.
- Do not operate buttons or the crown while the watch is wet or submerged in water.
- After exposure to saltwater, rinse the watch thoroughly with fresh water and dry it completely.
Solar Charging Care
To ensure continuous operation, expose the watch to light regularly. If the charge level drops too low, some functions may be disabled to conserve power.
