Laser 4000 prox sensors

The three 30mm prox sensors on the passenger side of the bridge for the front, middle and rear flags---do these need to be shielded or unshielded? I can not find it in the manual. And two units I bought have some of each.

Our high veolicty came with unshielded and we have always used unshielded on those flags.

It doesn't matter whether you use shielded or unshielded. Both will work.
