AutoCross-Laser ACL 4P RX
Preparing the calibration check:
It is possible for you to check the calibration of the laser. To do this, position
the device midway between 2 walls, which must be at least 5 metres apart.
Switch the device on (Laser cross ON). The best calibration results are achie-
ved if the device is mounted on a tripod. 1. Mark point A1 on the wall.

Note: If points A2 and A3 are more than 2 mm / 10 m, the device is in
need of calibration. Contact your authorised dealer or else the UMAREX-
LASERLINER Service Department.
Checking the vertical line: Position the device about 5 m from a wall. Fix a
plumb bob with a line of 2.5 m length on the wall, making sure that the bob
can swing freely. Switch on the device and align the vertical laser to the plumb
line. The precision is within the specified tolerance if the deviation between the
laser line and the plumb line is not greater than ± 1.5 mm.
Checking the horizontal line:
Position the device about 5 m from a wall and
switch on the cross laser. Mark point B on the wall.
Turn the laser cross approx. 2.5 m to the right and
mark point C. Check whether the horizontal line
from point C is level with point B to within ± 2 mm.
Repeat the process by turning the laser to the left.
