Light Emitting Angle
Laser beams are emitted from the emitting window of the RC-4R.
The angle of emitting laser beams is as follows.
Important
RC-4R should be kept aiming so that the TS/IS/QS always stays within the
above range of laser beam emission until the turn-round motions are
completed.
If the aiming is out of above range while RC-4R is in turn-round motions, the
turn-round could not be completed.

At greater distances, the laser light at the edge of the beam field (angle) will be weaker.
