To assure compliance with the Safety standard 21 CFR,Chapter 1.Subchapter J.
The U.S.bureau of Radiological Health requires the following information to be provided
to user:
It can be dangerous to look into the beam with optical equipment such as
binoculars and telescopes.
1) Specifications of laser radiation
A)The EDM module of the R-300X produces a visible light beam, which is emitted from
the telescope objective lens and the center hole of the instrument base plate.
The R-300X is designed and built to have a laser diode radiating at 620-690 nm.
B)Radiant power
The R-300X is designed and built to radiate a maximum average radiant power of
4.75mw.(0.95mw for the model without “NX”) from the telescope,and 0.95mw from
the center hole of the base plate.The user may be subject to this radiation as a
beam while operation until such time that the instrument is turned off.
2) The following labels are affixed to and must remain attached to this laser product.
A) The following certification label is located near the plate level:
“This laser product is complied with the provisions of 21 CFR 1040.10 and 1040.11.
For a Class II laser product.”
Or for R-300NX models:
“This laser product is complied with the provisions of 21 CFR 1040.10 and 1040.11.
For a Class IIIa laser product.”
B)Caution label is located near the exit aperture :
“AVOID EXPOSURE laser radiation is emitted from this aperture.”
C)Warning logotype is located on the surface of the telescope:
“CAUTION LASER RADIATION DO NOT STARE INTO BEAM”
Or for R-300NX models:
“DANGER LASER RADIATION AVOID DIRECT EYE EXPOSURE”
D)Warning label is located near the exit aperture.
3) Caution to maintain the safety in compliance with the standard
A)To maintain the safety standard,refrain from any operation, maintenance,or
adjustment other than described in this instruction manual.
B)Operation, maintenance or adjustment other than those specified in this instruction
manual may result in hazardous radiation exposure.
C)Maintenance and repair not covered in this manual must be done by an authorized
Pentax dealer.
D)The laser beam emission by the distance measurement can be terminated by
pressing F1 MEAS key.
E)Pressing laser key F2 LD POINT key can terminate the laser beam emission by the
laser pointer.
F)The laser beam emission by the laser plummet can be terminated by
pressing laser key.
