Important notices
– The laser points to the location that will be measured.
No objects may get into the laser‘s line of measurement.
– The device compensates the measurement for different room
temperatures. Therefore allow the device a brief adaptation period
when changing locations with large temperature differences.
– The device is only conditionally useable in outdoor areas and cannot
be used in strong sunlight.
– The measurement results of outdoor measurements may be influenced
or falsified by rain, fog and snow.
– In unfavourable conditions, e.g. with poorly reflecting surfaces, the
maximum deviation may be greater than 3mm.
– Carpeting, upholstery or curtains will not reflect the laser optimally.
Measure to flat surfaces.
– Measurements made through glass (window panes) can falsify
measurement results.
– An energy-saving function switches the device off automatically.
– Clean with a soft cloth. Water may not be allowed to penetrate
the housing.

Information on maintenance and care
Clean all components with a damp cloth and do not use cleaning agents,
scouring agents and solvents. Remove the battery(ies) before storing for

Calibration
The measuring device should be calibrated and tested on a regular basis
to ensure it is accurate and working properly. We recommend the me-
asuring device is calibrated every 1 - 2 years. If necessary, contact your
distributor or the UMAREX-LASERLINER service department.
