CAUTION. Refer all repair pr oblems to qualified service personnel.
Page xi has a list of phone numbers to call for service information.
Injury Precautions
Review the following safety precautions to avoid injury and prevent
damage to this product or any products connected to it.
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.
TFS3031 TekRanger/TekRanger 2 User Manual
vii
General Safety Summary
Optical Output. When a fiber is not connected to the Laser Output
port, the TFS3031 may emit laser light briefly in the following
circumstances:
H In IntelliTrace mode, during the connection status portion of the
test until the user either terminates the test or allows it to
continue under the ‘‘connection status’’ warning.
H During any non-automatic test until averaging is complete.
H During a real-time test until terminated by the user.
Power Sources. The TFS3031 is designed to operate from an
internal, rechargeable, 12 cell, 14.4 volt nickel-cadmium (NiCad)
battery , or a power/charger adapter rated at 9 to 16 volts DC, 40
watts.
Battery. Do not expose the battery to fire or intense heat. Do not
open or mutilate the battery. Avoid contact with released electrolyte
which is corrosive and may damage eyes, skin, and clothing. Check
with local codes for special disposal instructions. Only the entire
battery is replaceable. Individual cells are not replaceable.
External Power. Use only the power/charger adapter that is
specified for the TFS3031.
viii
CAUTION. The power/charger adapter is not hermetically sealed. Do
not expose it to moisture.
Fuse. The TFS3031 contains a 3.5 amp, 125 volt, fast-acting fuse on
the Power Supply board. The fuse is not user-replaceable.
Do Not Operate in Explosive Atmospheres. Do not operate the
TFS3031 in an explosive atmosphere unless it has been certified for
that kind of operation.
Do Not Remove Covers or Panels. Do not remove TFS3031 covers
or panels (except to access the battery), nor operate the instrument
without covers and panels in place.

Laser Output Port and Connector Adapter
Laser Output Port
The test fiber connects to the laser output port located on the side
panel. Light is emitted from the laser output port into the test fiber.
If both singlemode and multimode laser output ports are installed,
the singlemode port is in top position and multimode port in bottom
position. If one laser output port is installed, it will always be in the
bottom position. The ports are identified by label.

Port Functions
CAUTION. Do not fire the laser (push the START/STOP button)
unless a fiber is connected to the laser output port. Severe damage to
internal electronics can result.
Connector Adapter
The connector adapter attaches the fiber to the laser output port.
Connector adapters are packaged separately with new instruments,
and must be installed on the laser output port before use.
The connector adapter on the TFS3031 must match the connector on
the test fiber. See page 5–13 for a list of connector adapter options.
Connector Adapter Installation and Removal
Connector adapters are keyed for proper mating with the laser output
port.
T o install a connector adapter, align the keyed elements, slide the
connector adapter onto the laser output port, and turn clockwise until
the connector adapter is finger tight (see Figure 1–1).
1–2
T o remove a connector adapter, unscrew it counterclockwise and pull
it straight off the port.

CAUTION. Do not touch the exposed end of the laser output port with
anything but the proper cleaning materials. See page 4–1 for
cleaning instructions.
To protect against damage, all ports should be covered with their
dust caps when not in use.
RS232C Serial Port
