3) Move slide switch to TONE (OFF) when finished. The
™
Turbo Tone
draws no power when the leads are open,
but the leads touching during storage in CONT could
drain the battery.
Note: The signal is strong enough with TURBO on to light both
status LEDs. The NRM green LED will go out when continuity is
found and the red LED will be brighter.
To Supply Talk Battery Power
1) Move slide switch on left side of Turbo Tone
position. Be sure tone is off.

2) Connect Turbo Tone
in series with a phone set at one end
™
of a dead pair. To connect the Turbo Tone
phone set, connect one lead from the Turbo Tone
lead of the phone set and connect the two remaining free
leads to the dead wire pair.
3) Connect a second phone set to the dead wire pair at the
other end of the line.
4) Take both phone sets off hook and communications will
be established.
5) Move slide switch to TONE (OFF) when finished. The

Turbo Tone
draws no power when the leads are open,
but the leads touching during storage in CONT could
drain the battery.
To Send a Tone for Tracing
1) Move slide switch on left side of Turbo Tone
TONE (OFF) position for normal operation, especially
if toning powered phone lines. See Application Hints
below for other configurations.
2) Connect leads across the line or attach one lead to ground
and the other lead to one wire of a cable or pair to be traced.
3) Press the TONE button on the unit briefly to turn on
the signal. If the desired signal level indicator (HI or LO)
is not blinking, press the button briefly until the correct
™
signal level is selected. The Turbo Tone
rotates through
a HI-LO-OFF sequence.

4) Select a different signal type if desired, as described in
To Select or Verify Signal Type section.
5) To turn off the signal, press the TONE button briefly. If it
has been more than 15 seconds since the last press, the
Turbo Tone
may be necessary if the unit was set to HI.
6) Selecting the TURBO button will initiate the TURBO mode
and the unit will begin to generate up to 700% more tone
power output than when in regular HI and LO modes. The

unison when TURBO mode is on.
Application Hints: For long runs and when using the LO amplitude
in series with a
setting on to unbalance twisted pairs, turning on the TURBO

to one
mode increases the signal amplitude by over 500% . The TONE
(OFF) mode minimizes the internal load on the tone generator
and uses the minimum battery power.
When tracing wires terminated to a terminal block such as a
"66 block" or a patch panel, attaching both Turbo Tone
to the cable or pair tends to contain the signal within the cable.
The tracer must nearly touch the end of the cable to detect the
signal, which is helpful when the wires are close together as when
terminated. The LO amplitude setting may generate a stronger
signal when connecting both leads of the Turbo Tone
by reducing the field canceling effect of having a signal and its
return close together, especially in twisted pair cable. A modular
phone cable can be used to connect the Turbo Tone
a wall jack.

To maximize radiated signal while tracing along a cable run,
connect one lead of the Turbo Tone
the other end to ground (such as the case of an electrical box,
electrical conduit, metallic water pipe or ground rod). If no
ground is available, do not connect the other lead to anything;
let it dangle as near to the earth as possible. Connect the

shield will do its job if connected to the center lead and block
the tone. The LO amplitude setting is useful if there is too much
bleeding of the signal or the tracer being used has fixed volume
and is overloading.

There are several useful techniques that take advantage of the
ability to generate tone in any slide switch position. Both leads
™
of the Turbo Tone
must be connected to the pair in order for
them to work. With tone on, the CONT mode can be used on
a dead line to identify the line to a helper, or to verify having
found both leads of a pair. Once the pair is presumed to be
found, short out the pair and the REV LED should light on the
™
Turbo Tone
, indicating the pair has been found. The CONT
mode can also be used with tone to allow a phone set without
a passive monitor function to hear the tone when the phone
leads are attached across the pair the Turbo Tone
To Select or Verify Signal Type
™
The Turbo Tone
has three distinctly different tone types available
—one steady and two dual (or warble) tones.
1) Press and hold the TONE button until the four non-status
LEDs turn on (lamp test), this indicates entry into the tone
style selection function.
2) Continue holding the button down, one of the two LEDs will
turn on steady or flash to indicate the currently selected
type. The Single LED will turn on steady to indicate the single
type is selected. The Dual LED will either flash for one of
the dual tones or be on steady for the other. Releasing the
button before two seconds have passed will leave the signal
type unchanged.
3) To select another signal type, continue holding the button
down until the desired type is displayed. The Turbo Tone
will continue to cycle through the three types until the
button is released or the unit times out and turns off
(10 to 12 seconds).
Hint: The currently selected tone type is generated at the RJ
jack once the signal selection function is entered. Holding a
tone tracer near the jack will allow the user to hear each tone
type as it is selected.
