Hazards in use

CAUTION:

Watch out for erroneous distance measurements if the instrument is defective or if it has been dropped or has been misused or modified.

Precautions:

Carry out periodic test measurements. Particularly after the instrument has been subject to abnormal use, and before, during and after important measurements.

Make sure the Leica DISTO™ optics is kept clean and that there is no mechanical damage to the bumpers.

CAUTION:

In using the instrument for distance measurements or for positioning moving objects (e.g. cranes, building equipment, platforms, etc.) unforeseen events may cause erroneous measurements.

Precautions:

Only use this product as a measuring sensor, not as a control device. Your system must be configured and operated in such a way, that in case of an erroneous measurement, malfunction of the device or power

failure due to installed safety measures (e.g. safety limit switch), it is assured that no damage will occur.

WARNING:	GB
Flat batteries must not be disposed of with
household waste. Care for the environment and take
them to the collection points provided in accordance
with national or local regulations.
The product must not be disposed of with
household waste.
Dispose of the product appropriately in
accordance with the national regulations in
force in your country.
Always prevent access to the product by
unauthorized personnel.

Electromagnetic Compatibility (EMC)

The term "electromagnetic compatibility" is taken to mean the capability of the product to function smoothly in an environment where electromagnetic radiation and electrostatic discharges are present, and without causing electromagnetic interference to other equipment.

Leica DISTO™ D3a 776175a gb	3	Safety Instructions

WARNING:

The Leica DISTO™ conforms to the most strin-

GB	gent requirements of the relevant standards and
	regulations. Yet, the possibility of it causing interfer-
	ence in other devices cannot be totally excluded.

CAUTION:

Never attempt to repair the product yourself. In case of damage, contact the local dealership.

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.

•Consult the dealer or an experienced radio/TV technician for help

WARNING:

Changes or modifications not expressly approved by Leica Geosystems for compliance could void the user’s authority to operate the equipment.

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"

Safety Instructions	4	Leica DISTO™ D3a 776175a gb

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.)

Labelling

Inserting/replacing batteries

Changing the reference point (multifunctional endpiece)

1Remove battery compartment lid and attach handstrap.

2Insert batteries, observing correct polarity.

3Close the battery compartment again. Replace the batteries when the symbol flashes permanently in the display.

)	Only use alkaline or rechargeable batteries.
)	Remove the batteries before any long period

of non-use to avoid the danger of corrosion.

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.
