SAFETY GUIDE
For laser EDM (visible laser)
Warning:
The total station is equipped with an EDM of a laser grade---3R/
Ⅲ
a. It is verified by
the following labels.
Over the vertical tangent screw sticks an indication label “CLASS III LASER
PRODUCT”. A similar label is pasted on the opposite side.
This product is classified as Class 3R laser product, which accords to the following
standards.
IEC60825-1:2001 “SAFETY OF LASER PRODUCTS”.
Class 3R/
Ⅲ
a laser product: It is harmful to observe laser beam continuously. User
should avoid sighting the laser at the eyes. It can reach 5 times the emitting limit of
Class2/II with a wavelength of 400mm-700mm.
Warning:
Continuously looking straight at the laser beam is harmful.
Prevention:
Do not stare at the laser beam, or point the laser beam to others‟ eyes. Reflected laser
beam is a valid measurement to the instrument.
Warning:
When the laser beam emits on prism, mirror, metal surface, window, etc., it is
dangerous to look straight at the reflex.
Prevention:
Do not stare at the object which reflects the laser beam. When the laser is switched on
(under EDM mode), do not look at it on the optical path or near the prism. It is only
allowed to observe the prism with the telescope of total station.
Warning:
Improper operation on laser instrument of Class 3R will bring dangers.
