4. Scan the target. Press and hold the TRIGGER while panning
the instrument across the target. The tone changes pitch when
the instrument acquires the target. The highest pitch - the on-
target tone - should occur when the scope's red aiming dot is
centered on the target. Scan the target both horizontally and
vertically.
• If the frequency drops off at equal distances from the
center of the aiming dot,
the instrument needs no
adjustment.
• Otherwise,
continue with the Alignment Procedure
.
• When checking vertical alignment to a close target, be
aware of the offset between the center of the scope
and the center of the transmit lens, which is 2 inches.
• If you need assistance, contact Laser Technology, Inc.
See the inside front cover for LTI contact information.
Scope Alignment Procedure
The point of this procedure is to align the laser's point of impact with
the in-scope red aiming dot, using sound to indicate when the scope is
on-target. To align the scope properly, you will need:
• Two metric Allen wrenches to expose and turn the scope
adjustment screws. One 2.5 mm and one 1.5 mm.
• A target at which to aim the instrument.
• A highly stable base for the instrument.
A tripod is recommended.
Selecting a Target
The target that you choose is critical to the success of the alignment
procedure. The target should be reflective; and large enough that you
can see it from a distance, but small enough to be an accurate indicator
of where the laser beam is hitting.
• A bicycle reflector at least three inches in diameter is
recommended.
• The target should be at least 700 feet (200 meters)
from the instrument. It should be silhouetted against
the sky, with no other targets in the area. That’s so
you can be certain of the general area that the laser
is hitting.
