Warranty
The manufacturer warrants this instrument to be free from defects in material and workmanship under normal use
and service for the period of two years from date of purchase. This warranty extends only to the original purchaser.
This warranty shall not apply to fuses, batteries or any product which has been subject to misuse, neglect, accident,
or abnormal conditions of operation.
In the event of failure of a product covered by this warranty, the manufacturer will repair the instrument when it is
returned by the purchaser, freight prepaid, to an authorized Service Facility within the applicable warranty period,
provided manufacturer’s examination discloses to its satisfaction that the product was defective. The manufacturer
may, at its option, replace the product in lieu of repair. With regard to any covered product returned within the
applicable warranty period, repairs or replacement will be made without charge and with return freight paid by the
manufacturer, unless the failure was caused by misuse, neglect, accident, or abnormal conditions of operation or
storage, in which case repairs will be billed at a reasonable cost. In such a case, an estimate will be submitted
before work is started, if requested.
The foregoing warranty is in lieu of all other warranties, expressed or implied, including but not limited to any
implied warranty of merchantability, fitness, or adequacy for any particular purpose or use. The manufacturer shall
not be liable for any special, incidental or consequential damages, whether in contract, tort, or otherwise.
Software Warranty
The manufacturer does not warrant that the software described herein will function properly in every hardware and
software environment. This software may not work in combination with modified or emulated versions of Windows
operating environments, memory-resident software, or on computers with inadequate memory. The manufacturer
warrants that the program disk is free from defects in material and workmanship, assuming normal use, for a period
of one year. Except for this warranty, the manufacturer makes no warranty or representation, either expressed or
implied, with respect to this software or documentation, including its quality, performance, merchantability, or
fitness for a particular purpose. As a result, this software and documentation are licensed “as is,” and the licensee
(i.e., the User) assumes the entire risk as to its quality and performance. The liability of the manufacturer under
this warranty shall be limited to the amount paid by the User. In no event shall the manufacturer be liable for any
costs including but not limited to those incurred as a result of lost profits or revenue, loss of use of the computer
software, loss of data, the cost of substitute software, claims by third parties, or for other similar costs. The
manufacturer’s software and documentation are copyrighted with all rights reserved. It is illegal to make copies for
another person.

To prevent possible electrical shock, fire, or personal injury follow these guidelines:
• Read all safety information before you use the product.
• Use the product only as specified, or the protection supplied by the product can be
compromised.
• Do not use the product around explosive gases, vapor, or in damp or wet environments.
• Carefully read all instructions.
• Do not use and disable the product if it is damaged.
• Do not use the product if it operates incorrectly.
• Do not apply more than the rated voltage between the terminals or each terminal and earth
ground.
• Do not look directly into the laser with optical tools (for example, binoculars, telescopes,
microscopes). Optical tools can focus the laser and be dangerous to the eye.
• Do not look into the laser. Do not point laser directly at persons or animals or indirectly off
reflective surfaces.
• Do not use laser viewing glasses as laser protection glasses. Laser viewing glasses are used
only for better visibility of the laser in bright light.
• Use the product only as specified or hazardous laser radiation exposure can occur.
• Incorrect wiring can damage the sensor and void the warranty. Before applying power, make
sure all connections are correct and secure!
• To prevent possible electrical shock, fire, or personal injury make sure that the sensor is
grounded before use.
• Have an approved technician repair the product.
• The metallic enclosure of the sensor is not necessarily earthed by installation. At least one of the
following safety measures must be met to minimize the danger of electrostatic charges:
o Earth grounding of the cable shield
o Installing the unit’s metallic enclosure on an earth grounded mounting bracket or on any other
grounded bases
o Protect the operator from electrostatic discharge
