Safety Instructions
This meter has been designed for safe use, but must be operated with caution.
WARNING: Do not directly view or direct the laser pointer at an eye. Low power visible lasers
do not normally present a hazard, but may present some potential for hazard if viewed
directly for extended periods of time.
Laser classification (Class 2)
The DT500 produces a visible Class 2 laser beam from the top of the
instrument. Do not stare into the laser beam or direct the beam toward
anyone's eyes. Eye protection is normally an automatic response ('blink
reflex', for example).
Warning: Do not look directly into the laser beam using optical aids such
as binoculars or telescopes. This can create a hazard.
