Notice:
1. This product is infrared radiation type, the light source has been integrated in the machine, no external light source is needed; it is recommended to be used in weak light environment; the darker the ambient light, the better the machine performance. For outdoor use and under strong light conditions, a hood must be added
2. When measuring the velocity of the projectile at a higher velocity. Please take appropriate protective measures. Prevent projectiles from rebounding after hitting the machine and causing damage
3. When installing, pay attention to the marks on the left and right sides of the light bar, and the light bar with lights faces down
