3. Cover the reflector.
4.1 If the left-hand green LED goes off then the light being received by the detector is coming from the reflector and you can now proceed to
the alignment stage. See page 13 for Automatic Alignment or page 17 for Manual Alignment.
4.2 If the left-hand green LED stays illuminated with the reflector covered then the light received by the detector is being reflected by some
other object in or around the beam path.
Take care to make sure there are no reflective objects within 0.5 m of the centre of the beam path, and try Prism Targeting again.
4.3 If the amber LED flashes every second then the detector is not receiving enough light from the reflector. The number of flashes indicate
how strong a signal it is receiving. Using the direction buttons, move the detector in one axis until the amber flashes increase. If the
number of flashes stays the same, then keep going in the same direction. If the number decreases, then reverse direction. Once the
number of flashes starts to increase then keep going until either:
• The left-hand green LED comes on, at which point cover the reflector as described under point 3 above.
• The amber LED flashes start to decrease again, at which point reverse direction for 2 steps and perform the same process in the other
axis.
If Prism Targeting has been performed on both axes and the left-hand green LED is still not on, then ensure the following:
• Correct number of reflectors for the range has been used
• The distance has not exceeded the maximum (120 m)
• The reflector and detector are parallel to each other
After the above points are assured, try the Prism Targeting again.
• Avoid direct eye exposure to laser beam.
• Follow local regulations for use of products with Class 3R lasers
