FCC statement (applic. in U.S.)

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment

and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

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 unnecessarily. Eye protection is normally afforded by aversion responses including the blink reflex.

WARNING:



Looking directly into the beam with optical aids

(e.g. binoculars, telescopes) can be hazardous.

Precautions:

Do not look directly into the beam with optical aids.

CAUTION:



Looking into the laser beam may be hazardous

to the eyes.

Precautions:

Do not look into the laser beam. Make sure the laser is aimed above or below eye level. (particularly with fixed installations, in machines, etc.)

Changing the reference point (multifunctional endpiece)

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.

• 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.

A built-in sensor automatically detects the orientation of the positioning bracket and adjusts the zero point of the instrument accordingly.

Pressing the button starts the laser measurement. The display shows required stake out distance in the summary line between the stake out point (first a and then b) and the instrument (rear reference).

If the DISTO™ is then moved slowly along the stake out line the displayed distance decreases. The instrument starts to beep at a distance of 0.1m from the next stake out point.

The arrows in the display indicate in which direction the DISTO™ needs to be moved in order to achieve the defined distance (either a or b). As soon as the stake out point is reached the beep changes.

The function can be stopped at any time by pressing the button.

Indirect measurement

The instrument can calculate distances using Pythagoras’ theorem.

Make sure you adhere to the prescribed

)

sequence of measurement:

• Al l target p oints must be in a horizonta l or vertical plane.

• The best results are achieved when the instrument is rotated about a fixed point (e.g. with the positioning bracket fully folded out and the instrument placed on a wall).

• The minimum/maximum function can be used see explanation in "Measuring -> Minimum/ maximum measurement". The minimum value must be used fo r me asu rem en ts at ri ght ang les to the target; the maximum distance for all other measurements.

Make sure that the first measurement and the

distance to be measured are at right angles. Use the Minimum/maximum function, as explained in "Measuring -> Minimum/maximum measurement".

Measuring conditions

Measuring range

The range is limited to 100 m. At night or dusk and if the target is in shadow the

measuring range without target plate is increased. Use a target plate to increase the measurement range during daylight or if the target has poor reflection properties.

Target surfaces

Measuring errors can occur when measuring toward colourless liquids (e.g. water) or dust free glass, Styrofoam or similar semi-permeable surfaces.

Aiming at high gloss surfaces may deflect the laser beam and lead to measurement errors.

Against non-reflective and dark surfaces the measuring time may increase.
