Rotate the TD-units to the 12 o’clock position, using the spirit levels on the
TD rotating brackets. The led on the TD-M unit turns from flashing green to
alternate red and green when within ±3° of correct position. The targets
should be slid over the detectors. Adjust the lasers to the centre of both
targets using the blue adjustment screws.
Rotate the TD-units to the 9 o’clock position. Slide open the targets, wait
until the TD-values appear, and touch the 9 o’clock icon.
