the receiver at this centre.
2. Position the laser transmitter as close as possible to the first bore so that
the laser beam hits the centre of the target.
3. Rotate the receiver 180 o and slide it to correct half of the difference
between the laser spot and the centre.
4. Adjust the laser transmitter so that the laser beam hits the centre of the
target.
5. Move the receiver to the last bore. Adjust the angle of the laser beam
with the adjustment screws so that it hits the centre of the target.
