After attempting to calibrate the putter sweet spot or loft calibration:
The light level detected in the last operation was ###.
This is outside the optimal range of 170 to 220.
The V1 Visual Putting System requires appropriate light levels to be able to correctly detect the putter head and golf ball movements. After performing the PUTTER SET or CALIBRATE LOFT function, V1 Putt will check the light levels to ensure that they are inside the optimal range of 170 to 220. You can manually view the peak light levels by clicking the SETTINGS button and clicking LIGHT ADJUST. Adjust the exposure on your camera until the peak area (which corresponds with the white tape on the putter) falls between 170 and 220.
For more information, please refer to the Light Adjustment section in Chapter 3 - System Calibration in your V1 Putt User's Manual for detailed instructions on setting the proper lighting levels.
