PRECAUTIONS
1. Safety Precautions
The Measuring Unit connected to the Display Unit uses a very low power laser.
Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
1) The IEC standard provides for two classes of laser product: a Class 2 laser product uses
a visible laser (maximum power: 1.5 mW for scanning; laser device: semiconductor
laser; wavelength: 650 nm).
2) Do not look directly into the laser beam. (Even if it seems that no light is being emitted
from the emission window, do not look into it.)
3) Do not stare the laser beam directly through optical instrument, such as a magnifying
lens.
4) If measuring flat objects with mirror finishes, avoid looking at the reflection on the
surface.
5) Close the beam shutter when the instrument is not in use.
6) Do not remove the laser class identification labels attached to the Measuring Unit.
7) Before using this unit, carefully read the “Measuring Unit Specifications” and “Precau-
tions on Use of Laser” sections provided in the manual supplied with the Measuring
Unit.

2. Before making the connection between the Measuring Unit and the Display Unit, turn off the
power. If an optional device is to be connected to this system, make sure that the optional
device is also turned off.
3. Firmly tighten the screws of the cable connectors and interfaces to ensure shielding.
4. Do not touch the terminals of the connectors, otherwise contact may be poor.
5. Positively ground the Display Unit.
6. An error display may appear during operation. However, it may not always indicate a fault. If
an error display appears, consult the Maintenance and Inspection section.
Do not open the covers provided on the emission unit and reception unit.
