Monitors target acquisition.
Normally ON when target is acquired. It turns off when the laser is off the target, out
of range, or has a dirty lens.
Random or rapid flashing of this LED could indicate a weak signal caused by too
much of a reflector angle. Make sure the reflector is not bent, and that its orientation
is per Figure 14. Groove lines visible on the reflective material should be in the same
direction as the laser sensor orientation.
