WARNING.
INVISIBLE LASER RADIATION. To eliminate hazardous
laser radiation exposure, do not use controls or adjustments, or
perform procedures other than those specified in this manual.
Laser Radiation. The TFS3031 tests optical fibers by emitting short
pulses of laser light. The interval between pulses is large compared
to the pulsewidth. Although the pulsed power is in the milliwatt
range, the average power is only in the microwatt range. The light is
emitted through the Laser Output port on the right side-panel, and is
invisible to the human eye.
The TFS3031 is classified as a CFR Class I and IEC Class 1 laser
product under the Radiation Control and Health Safety Act of 1968,
and complies with 21 CFR 1040.10 and 1040.11.
Even though the TFS3031 is categorized as a Class I, 1 laser product
(the lowest classification), you should avoid exposing your eyes to its
light:
H
Do not look into the Laser Output port when the TFS3031 is
turned on.
H
Keep the dust cap on the Laser Output port when not in use.
H
Avoid looking at the free end of a test fiber (the end not
connected to the TFS3031). If possible, direct the free end toward
a non-reflective surface.
