Important Safety Information (cont’d)
Electric shock hazard:
• Fuse replacement should be performed by Tempo qualied personnel.
• Do not use repaired fuses or short-circuited fuse holders.
Failure to observe these warnings could result in severe injury or death.
The 930XC instruments are laser devices
conforming to the requirements of CDRH,
CFR 1040, Subchapter J. While there is no
potential for eye damage due to unaided
direct exposure, users should always avoid
looking directly into the output port. The
use of optical viewing instruments, such
as microscopes, magniers, etc., should
always be avoided. The use of such devices
around active bers can focus an intense
beam of light energy onto the retina of
the eye, which can result in permanent
damage.
Laser hazard:
• When performing measurements on ber optic systems, avoid eye exposure to any open-
ended bers, optical connectors, optical interfaces, or other sources because they may be
connected to active laser transmitters.
• Do not look into the optical port when a source is turned on.
• Avoid looking at the free end of a test ber, i.e., the end not connected to the instrument. If
possible, direct the free end toward a non-reective surface.
Failure to observe these precautions may result in injury.
