Configuración
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.
- Evite colocar el reloj en entornos extremadamente calientes durante la carga.
- 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.
Configuración de la hora y la fecha
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.

Funciones operativas
The PRO TREK PRG-650Y-1CR features a Triple Sensor for environmental data and various timekeeping modes.
Funciones del triple sensor
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.
- Brújula digital: 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.

Mantenimiento
Limpieza
La limpieza regular ayuda a mantener la apariencia y la funcionalidad de su reloj.
- Limpie el reloj con un paño suave y seco para eliminar la suciedad y la humedad.
- Para la suciedad difícil, utilice un cepillo suave y una solución de jabón suave, luego enjuague bien con agua fresca y seque por completo.
- Avoid using harsh chemicals or abrasive materials, as they can damage the watch's finish or seals.
Resistencia al agua
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.
- Después de la exposición al agua salada, enjuague bien el reloj con agua dulce y séquelo por completo.
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.
