WARNING
Invisible laser light is output from the OPTICAL OUTPUT terminal located on the front
face of this instrument. When Optical switch module connects to DTSX3000 with the
optical fiber, the laser beam is output from optical terminals of Optical switch module.
Do not look directly or indirectly into the laser beam or at a specular reflection of the
beam without protective equipment.
Do not aim the laser beam at the eye. The laser beam may cause blindness or damage
to your eyes. Attach the cover to the optical connector when it is not in use.
Using an optical instrument, such as a loupe, magnifying glass, or microscope, to
observe the laser beam from a distance of less than 100 mm may cause eye injury.
This instrument uses invisible laser light, which may cause eye injury or vision damage if
it enters the human eye. To prevent accidents, always observe the following precautions:
• Do not turn on laser output when no optical fiber is connected to the optical connector.
• Always stop laser output before disconnecting the optical fiber from the optical
connector.
• Never look into the end of an optical fiber connected to the optical connector during
laser output.
• Never direct the laser beam into an area where a telescope optical instruments (for
example, telescopes and binoculars) are likely to be used.
High-power laser light may be emitted during disassembly and modification of this
instrument. For this reason, customers must not disassemble or modify this instrument
under any circumstance.
Operating this instrument not in accordance with procedures described in this manual
may result in exposure to hazardous laser emissions.
