Congratulations on your purchase of
MICRONETBLINK
and/or
MICROPROBE!
The MICRONETBLINK is a practical network installa-
tionandtroubleshootingtoolthatflashesahublight,
features a unique tone signal, two test leads, 8-
conductor twisted pair cable (RJ45), and a 4-con-
ductor modular cable (RJ11) to test standard Cat 5
cabling, COAX cables, and bare wires.
MICRONETBLINK also does continuity tests and
checks tip/ring telephone signals. The signal emit-
ted by the MICRONETBLINK can be easily traced by
the MICROPROBE, even when cables are in a bundle
or hidden in walls or ceilings. Use MICRONETBLINK
and MICROPROBE to locate hub ports, verify cable
continuity, determine line polarity and voltage in
localnetwork twisted pair cabling andmodular tele-
phone lines. The MICROPROBE is equipped with a
tone amplifier and an LED indicator that detects
audible frequency tones for accurate tracing and
identification of wires.

MicroNetBlinkTM / MicroProbeTM
Battery
MICRONETBLINK requires a 9 Volt Alkaline battery.
MICROPROBE requires a 9 Volt Alkaline battery.
The low Battery LED will light up when a low
battery condition is detected.
Using the units with a low battery may effect the
test accuracy.
If the units are stored for more than one month,
the battery should be removed.
High Voltage Protection
Do not touch the tip of MICROPROBE to the active
circuit contact or line.
Remember to adjust the volume rotary to reach
an ideal volume level.
Do not expose the units to extreme humidity or
direct sunlight.
Do not open the units or attempt to repair in case
of malfunction. Please send it back to your
distributor for repair or replacement.
MICRONETBLINK is designed to withstand input
voltage conditions that arise from normal
telephony applications such as 48 VDC at less
than 80 ma or 24 VAC used to power many
keysets. Tests cannot be performed when hazard
conditions exist on the inputs.

MICRONETBLINK
Tests
Flashing the Hub Light Status
1. Set the toggle switch to the Signal position.
2. Plug the 8-position cable (RJ45) into the jack
to be tested.
3. Verify that the button on the face of the
MICRONETBLINK IS in the NETBLINK position.
4. In the wiring closet, view a light that blinks
once every 4 seconds at the port to which the
cable is connected.
MICRONETBLINK will blink the hub's status
indicator to assist locating a single channel in a
busy wiring closet.
Sending a Tone
1. Set the toggle switch to the Signal position.
2. Connect the black lead to ground and any
other cable (coax, RJ45, or red alligator) to
the cable to be traced.
3. Press the button to TONE position to
activate the toner.
4. Reception of the tone will be loudest (Speaker)
or brightest (LED) on the wire under test.
Caution: Do not connect to an active AC circuit
exceeding 24 V in this mode.
MicroNetBlinkTM / MicroProbeTM
Identifying Telephone Line Polarity
1. Set the toggle switch to the Off/Volt ü
position.
2. Connect the black alligator test lead to the TIP
(+) connection, usually green or blue.
3. Connect the red alligator test lead to the RING
(-) connection, usually red or marked R.
The LED indicator will light up:
GREEN indicates normal polarity
RED indicates reversed polarity
RED/GREEN indicates presence of AC power
on the telephone line
Verifying Telephone Lines
1. Set the toggle switch to the Off/Volt ü
position.
2. Insert the standard 4-pin modular cable into
the modular wall jack, or connect the red
alligator test lead to the RING (-) and the black
alligator test lead to the TIP (+).
The LED indicator will light up:
GREEN indicates a correct wired telephone
circuit that is on-hook
GREEN (DIM) indicates a correct wired
telephone circuit already in use or off-hook
RED indicates a reversed polarity phone circuit
3. Use a second phone line to dial the number
under test.
RED and GREEN (rapidly flashing) indicates a
ringing signal.

4. Set the toggle switch to Cont üto answer the
line or go off-hook.
Note: The brightness of the GREEN line status is
an indicator of the amount of telephone loop
current present while the toggle switch is in the
Cont
ü
position.
CAUTION: Telephone circuit voltages can be
hazardous, never touch the metal of the test
leads while the MicroNetBlink is attached to a
telephone line.
Testing for Low Voltage
CAUTION: MicroNetBlink is designed for
checking low voltage (less than 24 Volts DC or
AC only). Do not connect to any high voltage
circuits!
1. Set the toggle switch to the Off/Volt ü
position.
2. Connect the red alligator test lead to a wire of
the pair or circuit.
3. Connect the black alligator test lead to the
other wire of the pair or circuit.
If the LINE STATUS is GREEN, the black test
lead is connected to a NEGATIVE(-) DC Voltage
If the LINE STATUS is RED, the black test lead
is connected to a POSITIVE (+) Voltage
If the LINE STATUS is RED/GREEN, AC Voltage
is present.
