it is not used for a longer period of time. Do not store the distance meter
at temperatures above 50 C, as this can damage the LCD. Use a soft,

clean, slightly damp cloth to clean the device. The laser beam must reach
its target, then refl ect and return to the device. As a result, the measurement
conditions are subject to limitations. Too bright light at the measuring point
or too refl ective a surface, e.g. glass, can make measurement diffi cult or
impossible. In this case, change the measurement conditions or select the
appropriate measurement method.

TOOL OPERATION

Installing and replacing batteries (II)
Open the battery compartment cover located in the bottom back part of the
device. The cover is secured with a latch. Install Ni-MH batteries or accu-
mulators in the slots. Pay attention to the correct polarity. Batteries or accu-
mulators must always be replaced in sets. In order to ensure the correct and
longest possible operation of the device, it is recommended to use branded
alkaline batteries. To extend the life of batteries or accumulators, the device
will turn off the laser pointer after about 30 seconds and turn off the power
after about 3 minutes after any button has been pressed.

always starts in a single measurement mode and remembers the previously

The measurements that are not saved are erased when the product is
switched off , either automatically or by the user.
Changing the unit of measure

The measurement base can be changed by pressing and holding the button
marked +/- for about 2 seconds. The selected measurement base will be
visible in graphical form on the display.
