Note:
If points A1 and A5 are more than 3 mm / 10 m, the device is in need of
calibration. Contact your authorised dealer or else the UMAREX-
LASERLINER Service Department.
Checking horizontal calibration:
1. Mark point A1 on the wall. Attach the device in the centre of point A1,
align it, and switch it on. Adjust the laser line so that it reaches the end of
the wall, see page 12.
2. Mark point A2 and continue until point A5 is marked. Divide the distance
between A1 and A5 by the overall length (S1 + S2 + S3 + S4). The device
is within the tolerance if the difference between A1 and A5 is not greater
than 3 mm / 10 m.

Checking vertical calibration:
Fix a plumb bob with a line at least 2.5 m in length on the wall, making sure
that the bob can swing freely. Attach the device at the end of the plumb line
in the centre, align it vertically and switch it on. The precision is within the
tolerance if the deviation between the laser line and plumb line is not greater
than 3 mm / 10 m.
