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.
Do this by turning the unit on, thus releasing the transport restraint (cross
laser on). Please use a tripod.
1.
Mark point A1 on the wall.
2.
Turn the device through 180° and mark point A2.
You now have a horizontal reference between points A1 and A2.

Performing the calibration check:
3.
Position the device as near as possible to the wall at the height
of point A1.
4.
Turn the device through 180° and mark point A3. The difference
between points A2 and A3 is the tolerance.
When A2 and A3 are more than 0,2 mm / m apart, an adjustment
is necessary. Contact your authorised dealer or else the UMAREX-
LASERLINER Service Department.
