Targeting step by step

1. Switch on the beam detector. Push the mode switch (Fig 12) up to
'prism targeting mode'.
2. Pan and tilt the beam detector, by turning the thumbwheels, until
the centre of the beam hits the part of the refl ector shown in Fig 10b,
DIP
causing the red LED to fl ash. It does not matter which way you move
the detector. If moving in one direction does not cause the red LED
to fl ash, move the other way.
3. When the red LED fl ashes, select either pan or tilt (it does not matter
which you do fi rst) and continue adjusting the detector until the red
fl ash reaches its maximum. Continue the adjustment until the red
LED goes out and the amber LED starts to fl ash.
4. When the amber LED starts to fl ash keep turning the thumbwheel
and start counting the number of steps.
5. Stop turning the thumbwheel when the amber LED goes out and
the red LED starts fl ashing.
6. Turn the thumbwheel back half the number of steps counted. The
amber LED should still be fl ashing.
7. Move the other thumbwheel until the amber LED has just gone out
and the red LED is at maximum fl ash. Again, it does not matter which
way you turn fi rst.
8. At this point reverse the movement and, when the amber LED starts
to fl ash, proceed as in steps 4 to 6.
Note: At this point it is essential to test that the refl ector and not
another surface is refl ecting the beam. Cover the refl ector with a
non-refl ecting object and check that both LED indicators are off.
