Users Guide
The NX8 Pocket Toner lets you quickly do tests
for continuity, short circuits, ac and dc voltage,
and 50 Ω or 75 Ωtermination. The standard
adapters let you use the toner on cable with
F-type connectors. Optional adapters let you
use the toner on twisted pair, coaxial, and
two-wire radial cable.
The optional Dial Tone Detective™lets you
quickly see if a dial tone is present at a
telephone jack and if the polarity of the wires
is correct.
Safety Information
Warning or Caution: Risk of damage
to or destruction of equipment or
software. See explanations in the
manual.
Warning: Risk of electrical shock.

Warning
To prevent possible fire, electric shock, or
personal injury:
• Do not connect the toner to more than 30
Vac, 42 Vpk, or 60 Vdc.
• This equipment has no insulation against
on-hook, dial tone, ring, or transient
voltages. Those voltages can be
hazardous and can exist on active
telecommunication circuits. Do not use
this equipment on active circuits where
these voltages can exist. Disconnect the
circuits at the source before connecting
this equipment.
• Do not use in a damp or wet
environment.
• Protection may be impaired if Product is
used in a manner not specified.
Do not connect this equipment to
public communications networks,
such as telephone systems. See the
warning below.

unit.
3 Turn on the main unit, then connect it to
the near end of the cable.
4 Read the display on the main unit:

Notes
The toner cap emits a loud, steady tone
when it has is continuity with the main
unit.
If the condition of the line changes, the
main unit emits a loud, brief tone.
A blinking dash indicates an open
circuit.
A blinking "S" indicates a short
circuit.
A "C" indicates continuity with the
toner cap or a 50 Ω or 75 Ω
terminator
Solid: DC voltage is present (>6 V dc).
Blinking: AC voltage is present
(>6 V ac).
The numbers 1 through 8 indicate
continuity with one of the eight ID
caps.

How to Detect Dial Tones
1 Connect the optional Dial Tone Detective
to a telephone jack.
To hear a tone when a dial tone is present,
use the Speed 81 coupler to connect the
toner cap to the Dial Tone Detective.
2 If there is a dial tone, the green LED is on.
If the jack is reverse-wired, the red LED is
on.
