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.

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.
