Using the R10 on the range in the dark

Hello,

I wondered if any of you used the R10 during the evening when the range was in the dark.

Is it not possible to use? I noticed very strange numbers when hitting the ball.

Thank you,

I use the range at night and they turn off the lights at a specific time. I've hit a few more balls and performance is normal.

Radar isn't be affected by light at all.
