binoculars and telescopes.
1) Specifications of Laser Radiation
A) The EDM module of the R-300 produces a visible light beam, which is
emitted from the telescope objective lens and the center hole of the
instrument base plate. The R-300 is designed and built to have a laser
diode radiating at 620-690 nm.
B) Radiant power
The R-300 is designed and built to radiate a maximum average radiant
power of 4.75mw. (0.95mw for the model without “N”) 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 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-300 N 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.
