5.2 Taking a Measurement
- Point the front of the Speedster V directly at the moving object you wish to measure. For optimal accuracy, aim for a frontal measurement.
- Press and hold the red trigger button. The device will continuously measure the speed of objects within its detection range.

5.3 Detectable Direction
The Speedster V can detect the speed of objects that are both approaching the device and receding from it.
6. Measurement Tips
- Optimal Positioning: For sports like baseball, it is recommended to measure from the umpire's position for the most accurate ball speed readings.
- Angle of Measurement: The accuracy of the measurement can be affected by the angle between the device and the moving object. For highest accuracy (±1 km/h), aim for a direct frontal measurement. When there is an angle, the accuracy may be ±2 km/h or more.
- Distance: Be aware of the maximum detectable distances for different objects to ensure a successful reading.
7. Maintenance
- Cleaning: Wipe the exterior of the device with a soft, lint-free cloth. Do not use harsh chemicals or abrasive materials.
- Storage: Store the Speedster V in its carrying case in a cool, dry place when not in use. Remove batteries if storing for extended periods.
- Lens Care: Keep the radar lens clean and free from smudges or debris to ensure accurate readings.
8. Troubleshooting
If you encounter issues with your Speedster V, refer to the following common solutions:
- No Power: Check battery installation. Ensure batteries are fresh and inserted with correct polarity.
- Inaccurate Readings: Ensure you are aiming directly at the object. Verify that the object is within the maximum detectable distance. Environmental factors like heavy rain or fog can affect radar performance.
- No Reading Displayed: Make sure the trigger button is pressed and held while the object is moving. Ensure there are no obstructions between the device and the target.
If problems persist, contact customer support.
