Safety Instructions
Admonishments
Important safety instructions are in this manual. In addition to the instructions on
the following page, there are other safety instructions you must follow. These
instructions involve lasers, lightwave optical cable and connectors, and
precautions when handling circuit packs to prevent damage from electrostatic
discharge. This manual also contains admonishments in the form of DANGERS,
WARNINGS, and CAUTIONS which must be followed at all times.
These admonishments have the following definitions:
■
DANGER indicates the presence of a hazard that will cause death or severe per-
sonal injury if the hazard is not avoided.
■
WARNING indicates the presence of a hazard that can cause death or severe per-
sonal injury if the hazard is not avoided.
■
CAUTION indicates the presence of a hazard that will or can cause minor per-
sonal injury or property damage if the hazard is not avoided. The caution is also
used for property-damage-only accidents. This includes equipment damage, loss of
software, or service interruption.
The alert symbol is used on product labels and in this manual to alert the
user to important operating and maintenance instructions.
Lightwave Safety
A Lucent Technologies lightwave digital transmission system and associated
optical test sets use semiconductor laser transmitters. The lasers emit lightwaves,
at or near infrared wavelengths, into lightguide cables. This light is at the red end
of the visible spectrum.
Although, at present, the transmitter power levels are below those known to cause
injury to the eye, for example, from direct inadvertent exposure to the end of an
energized fiber; direct exposure at close distances should be avoided.
!
WARNING:
Never view any unterminated optical fiber (including an unconnected con-
nector) with optical instruments other than indirect image-converting
devices such as the FIND-R-SCOPE
*
, since viewing optics tend to colli-
mate and concentrate the energy from an optical fiber and, hence,
increase the potential risk for injury.
