2. Safety Information
Please read and understand the following safety precautions before operating the device:
- Laser Safety: The system uses a low-power laser. Avoid direct eye exposure to the laser beam. Do not point the laser at people or animals.
- Battery Safety: Use only the provided charging cable. Do not attempt to open or modify the battery compartments. Avoid exposing batteries to extreme temperatures or direct sunlight.
- Environmental Conditions: Operate the system within recommended temperature and humidity ranges. Avoid using in heavy rain or extreme dust conditions.

3. Setup Guide
Follow these steps to set up your Ousmile Wireless Laser Sprint Timer System:
3.1 Charging the Units
Before first use, fully charge the Digital Display Unit, Laser Emitter Unit, and Laser Receiver Units. Connect the charging cable to the charging port on each unit and to a suitable USB power source. A full charge typically takes approximately 4 hours and provides up to 10 hours of operation.

3.2 Assembling the Tripods and Units
- Extend the legs of each tripod stand to a stable position.
- Mount the Digital Display Unit onto one tripod stand.
- Mount the Laser Emitter Unit onto a second tripod stand.
- Mount the two Laser Receiver Units onto the remaining two tripod stands.
3.3 Positioning the System
For a standard sprint timing setup, position the units as follows:
- Start Line: Place one Laser Emitter Unit and one Laser Receiver Unit opposite each other at the starting line. Ensure the laser beam is aligned horizontally and passes through the center of the receiver's detection area.
- Finish Line: Place the second Laser Receiver Unit and the Digital Display Unit opposite each other at the finish line. The laser beam from the Emitter Unit at the start line should pass through the detection area of the Receiver Unit at the finish line.
- Alignment: Adjust the height and angle of the units on their tripods to ensure the laser beams are perfectly aligned and unbroken between the emitter and receivers. The system is designed to reject interference from visible light, allowing for reliable operation even in sunlight.

4.2 Starting and Stopping the Timer
- The timer automatically starts when the laser beam at the start line is broken (e.g., by an athlete passing through it).
- The timer automatically stops when the laser beam at the finish line is broken.
- The elapsed time will be displayed on the Digital Display Unit.
4.3 Reading the Display
The LED digital tube display is designed for clear visibility in various lighting conditions, including indoors, outdoors, day, or night, with no strobe effect.

5. Maintenance
Proper maintenance ensures the longevity and accuracy of your timer system:
- Cleaning: Use a soft, dry cloth to clean the display and unit surfaces. For stubborn dirt, a slightly damp cloth can be used. Avoid abrasive cleaners or solvents.
- Battery Care: Recharge the units regularly, especially if they will be stored for an extended period. Do not allow batteries to fully discharge for long durations.
- Storage: When not in use, store all components in the provided aluminum carrying case. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Laser Lens: Keep the laser emitter and receiver lenses clean and free of dust or smudges to ensure accurate beam detection.
