movement of the red laser dot.
☞
The maximum diameter of the circular movement
described by the centre of the laser dot should not
exceed 3mm at a height of 1.5m.
5. If the centre of the laser dot describes a perceptible circular move-
ment, or moves more than 3 mm away from the point which was
first marked, an adjustment may be required. Inform your nearest
Leica Geosystems authorised service centre. Depending on bright-
ness and surface, the diameter of the laser dot can vary. At 1.5 m, it
is about 2.5 mm.

Adjusting the Laser Guide

To avoid moisture or dust entering the Laser Guide compartment, adjustment
screws and screw covers must be fixed after each adjustment procedure.
The recommended adjustment procedure is designed for distances of 50 m
and 120 m. Use the adjustment drawing, which is showing a TS16 G telescope,
with crosshairs for line of sight and Laser Guide. Look trough the telescope
and aim to the crosshairs of the telescope. For well-adjusted Laser Guides, the
laser beam should exactly match the circles for 50/120 m.
Make sure, adjustment screws are accessible during adjustment.
Make sure, the position of the telescope remains still. Check the target by
looking trough the telescope.
Adjustment procedure might be repeated to achieve high precision adjust-
ment.
Please enlarge this target plate to 200% prior to using it for adjustment.
