۱. دستورالعملهای راهاندازی
Follow these steps to set up your YWBL-WH Wireless Racing Timer:
- دستگاه های شارژ: Before first use, fully charge the Wireless Racing Timer and the Rebound Device using the provided charging cables and power adapters. The charging input voltage is DC 5V. A full charge takes approximately 5 hours.
- Assemble Stands: Attach the timer, rebound device, and reflectors to their respective brackets and then to the ground stands. Ensure they are securely fastened.
- Position the Timer and Rebound Device: Place the Wireless Racing Timer at the desired start/finish line. Position the Rebound Device directly opposite the timer, ensuring the laser beam from the timer hits the reflector on the rebound device. The effective laser distance is over 8 meters.
- Align Reflectors: Ensure the reflectors are clean and positioned to accurately reflect the laser beam. Proper alignment is crucial for accurate timing.
- روشن کردن: Locate the power switch on the side of the Wireless Racing Timer and the Rebound Device. Switch both devices to the 'ON' position.

6. دستورالعمل های عملیاتی
Once set up, operating the YWBL-WH Wireless Racing Timer is straightforward:
- زمانبندی خودکار: The system automatically starts timing when the laser beam is broken (e.g., by a person or object passing through it) and stops when the beam is re-established or broken again at the finish line (depending on configuration).
- خواندن صفحه نمایش: The 5-digit display on the Wireless Racing Timer will show the elapsed time in seconds, typically to three decimal places (e.g., 3.180 seconds).
- No Manual Reset: The timer is designed for continuous operation without requiring manual resets between timing intervals, streamlining the process for multiple participants or laps.
- خاموش: After use, switch both the Wireless Racing Timer and the Rebound Device to the 'OFF' position to conserve battery life.
