3) With the right slide switch in “Talk”
position.
This provides additional battery
power to enable voice
communication over the inactive
circuit.
4) Place both Test Sets “Off Hook” or
“Talk” position to establish
communications.
5) Move the left slide switch to
“Off/Line” position to avoid draining
battery.
(C) Testing Wire/Cable Continuity
! Do not connect to AC or DC
voltage circuit in “Cont” mode.
Before connecting an unknown
cable/wires to the Net toner in “Cont”
mode, use the OFF/LINE mode to check
and ensure that the cable/wires are not
powered.
Connecting the live powered cables in
“Cont” mode will damage the Net Toner.

1) With the left slide switch in
“Cont/Talk” position.
2) Connect the red and black alligator
test leads to both ends of the
cable/wire you want to test.
3) The “Cont” LED indicator will light
Green. Bright green indicates a
low resistance path. Dim green
indicates a high resistance path.
Unlit indicates an open circuit.
4) When a short circuit is detected, the
〝Cont〞LED indicator will light
Green, an audible sound will be
heard simultaneously (PR-608A
only).
5) Move the left slide switch to
“Off/Line” position to avoid draining
battery of clip leads touch during
storage.
Installed cables too long to test by alligator
clips.
1) Place a termination device on the far end
of the cable, connecting the 2 pins that
11
you wish to test or simply connect the
two wires manually.
2) Attach the alligator clips to the 2 pins that
you wish to test.
3) Read results on the “Cont” LED. A lit
LED indicates that the cable is
continuous. An unlit LED indicates that it
has a break at some point.
Coax Cable Testing
a. Test terminated Coaxial Cables Connect
the red test lead to the connector housing
and the black test lead to the center pin
or to the ground.
b. Test un-terminated Coaxial Cables
Connect the red test lead to the outer
shield and the black test lead to the
ground or to the center conductor.
(D) Line Polarity Test:
To determine the polarity of a wire pair and
identify Tip and Ring.
! Do not connect to circuit carrying AC
voltage in “Line” mode.
1) With the left slide switch in “Off/Line”
position.
12
2) Connect the red lead to the Ring(-)
Connection, and the black test lead to
the Tip(+) Connection.
3) To check Line 2 (3/6 pins) polarity use
the RJ12 modular plug connection.
4) Green indicates normal polarity
Red indicates reversed polarity
Flickering Red and Green indicates
presence of AC power or ringing line.
A dim LED indicates a busy or faulted
line.
If the 3/6 or and 4/5 LEDs is off, there
is no DC voltage on the line.
5) Dial the line to be verified. If the toner
is connected to the correct line, the
Line 1 LED will flickering red and green.
6) Monitor the line, move the slide switch
to “Cont” position.
This will terminate the call to confirm
the identification.
When not in use, the Net Toner’s
cables can be kept bundled and
organized by using the convenient
Velcro cable strap attached to the
cables near the Net Toners’ housing.
