Laser classification
Integrated distancemeter
The Leica DISTO™ produces a visible laser beam which emerges from the
front of the instrument.
It is a Class 2 laser product in accordance with:
• IEC60825-1 : 2007 "Radiation safety of laser products"
Laser Class 2 products:
Do not stare into the laser beam or direct it towards other people unne-
cessarily. Eye protection is normally afforded by aversion responses inclu-
ding the blink reflex.

Inserting/replacing batteries
See figure {A}
1 Remove battery compartment lid and attach handstrap.
2 Insert batteries, observing correct polarity.
3 Close the battery compartment again. Replace the batteries when the
symbol flashes permanently in the display.
Remove the batteries before any long period of non-use
)
to avoid the danger of corrosion.
Use alkaline batteries or rechargeable batteries only.
)
Changing the reference point (multifunctional
endpiece)
See figure {B}
The instrument can be adapted for the following measuring situations:
• For measurements from an edge, fold out the positioning bracket until
it first locks in place. See figure {C}.
• For measurements from a corner, open the positioning bracket until
it locks in place, then push the positioning bracket lightly to the right
to fold it out fully. See figure {D}.
A built-in sensor automatically detects the orientation of the positioning
bracket and adjusts the zero point of the instrument accordingly.

The graphics screen of the measurement window is split into different
areas. Top left is the brightest field, which contains the currently selected
measuring program. Just to the right appears the program submenu, which
shows the measuring programs that can be selected by pressing the same
key the required number of times.
The measurement field contains the individual measurements of the
measuring program with reference to a series of separate distance measu-
rements. Three lines are provided for this. A horizontal line separates the
measurement field and the result bar from one another. A red triangle indi-
cates whether the selected measuring program has a detailed display avai-
lable.

Digital pointfinder (3x zoom)
The device has an integral digital pointfinder, which shows the target
directly on the display. The displayed crosshairs allow precise measure-
ments to be made even though the laser beam is not visible. See drawing
{F.2}
The integral coloured digital pointfinder is a great help outdoors and can
be used in every function. Longer distances and precise measurements on
detailed surfaces can even be accomplished in bright sunlight without any
problem.
The 3x zoom allows the image to be magnified to suit the user's require-
ments.
Press the key to activate the function. Press the key again to
operate in a 1x, 2x or up to 3x zoom view.
