ATTENTION, LASER RADIATION – LASER CLASS 2
Never look directly into the beam!
The device satisfies the requirements of IEC 60825-1:2007 (EN 60825-1:2007) safety regulations for a product in laser class 2 as well
as the U.S. 21 CFR 1040.10 regulations with deviations corresponding to "Laser Notice No. 50" from June 24th, 2007.
Never look directly into the laser beam or in the direction of reflecting laser beams!
If you look into the beam path over a longer time period, there is a risk of injury to the retina.
Do not point the laser beam of the device at persons!
Interrupt the laser beam using a non-transparent, non-reflective object if the laser beam is accidentally directed towards a person.
When mounting and aligning the device, avoid reflections of the laser beam off reflective surfaces!
CAUTION! Use of controls or adjustments or performance of procedures other than specified herein may result in hazardous light
exposure.
Adhere to the applicable legal and local regulations regarding protection from laser beams.
The device must not be tampered with and must not be changed in any way.
There are no user-serviceable parts inside the device.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
NOTICE
Affix laser information and warning signs!
Laser information and warning signs are affixed to the device(see ). In addition, self-adhesive laser information and warning signs
(stick-on labels) are supplied in several languages (see ).
Affix the laser information sheet with the language appropriate for the place of use to the device.
When using the device in the US, use the stick-on label with the "Complies with 21 CFR 1040.10" notice.
Affix the laser information and warning signs near the device if no signs are attached to the device (e.g. because the device is too
small) or if the attached laser information and warning signs are concealed due to the installation position.
Affix the laser information and warning signs so that they are legible without exposing the reader to the laser radiation of the device
or other optical radiation.
