Safety Terms in this Manual
The WARNING heading in this manual explains dangers
that could result in personal injury or death.
The CAUTION heading in this manual explains hazards
that could damage these instruments.
In addition, a NOTES heading gives information to the user
that may be beneficial in the use of these instruments.
General Warnings and Cautions
The following general warnings and cautions are applicable
to these instruments:
LASER SAFETY
The TOPI 40,150,160, and 300 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, magnifiers, etc.) should always be
avoided. The use of these devices around active fibers can
focus a highly intense beam on to the retina which can
result in permanent eye damage.

Specific Precautions
Power Sources. The TOP series is designed to operate
from two AA alkaline batteries. Note proper orientation of
batteries before turning the instrument on.
Battery Power. Do not expose battery to fire or intense
heat, nor open or mutilate the battery. Avoid contact with
electrolyte which is corrosive and may damage eyes, skin
and clothing. Check with local codes for disposal
instructions.
External Power. Any external power adapter is not
recommended for the TOP series.
Laser Radiation. When making measurements on optica!
systems, avoid eye exposure to any open-ended fibers,
optical connectors, optical interfaces or other sources,
because they may be connected to laser transmitters
• Do not look into the optical port when a source is turned
on.
• Keep the dust cap on the optical port when not in use.
• Avoid looking at the free end of a test fiber (the end not
connected to the instrument). If possible, direct the free end
toward a non-reflective surface.
Do Not Operate in Explosive Atmospheres. Do not
operate the TOP series in an explosive atmosphere unless
it has been specifically certified for such operation.
Do Not Remove Covers or Panels. Do not remove the
instrument covers or panels, nor operate without covers and
panels in place.
Repair. Refer ail repair problems to qualified service
personnel.
