INSTRUCTIONS FOR USE

To Check the Status of a Phone Circuit

1) Move slide switch on left side of Turbo Tone™to the
STATUS position.

2) Connect black lead to TIP and the red lead to RING

or one

lead to each wire of the pair if designation is unknown.

• If

™

NRM lights up, it means the polarity is correct and the

black lead is connected to TIP.

• If the

REV lights, then the leads are reversed.

• If the

NRM or REV LED is bright, the line is not in use.

• If the LED is dim, the circuit is in use.

• If both

NRM and REV are on or flashing, an AC voltage

is present.

Application Hints: The TIP signal is nominally at ground potential.
Attaching the black lead to a ground point and connecting the
red lead to each wire of the pair can identify the RING line. When
the red lead is connected to RING, the

The status LEDs also indicate a ringing line by both
REV LEDs flashing brightly. To verify a phone line, connect the
Turbo Tone

™

in STATUS mode to the line to be tested and call

that line’s number from another line. The Turbo Tone

NRM LED will light.

NRM and

™

status

LEDs should indicate a ringing line.

Note: The RJ jumper cable that has been provided with the

Turbo Tone

™

uses a unique colored modular connector
that can be plugged into a RJ11 jack or a RJ45 jack
without damaging either. Thereby allowing CAT 5 output
points to be accessed without using an adapter.

Warning!

Do not attach to live AC circuits. This could cause an extreme
shock hazard and damage the Turbo Tone

STATUS mode.

To Check Continuity of a Circuit

Use only on non-energized circuits. Any energy present may
damage the Turbo Tone

™

or cause erroneous results. Turn off

tone if necessary.

1) Move slide switch on left side of Turbo Tone

™

to the

CONT position.

2) Connect one lead of Turbo Tone

™

to each end of the circuit
to be tested. If the DC resistance of the path is approximately
11,000 ohms or less, the

REV LED will light.

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™to the CONT
position. Be sure tone is off.

2) Connect Turbo Tone
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.

To Send a Tone for Tracing

1) Move slide switch on left side of Turbo Tone™to the
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

is not blinking, press the button briefly until the correct
signal level is selected. The Turbo Tone

setting on to unbalance twisted pairs, turning on the

mode increases the signal amplitude by over 500% . The TONE

mode minimizes the internal load on the tone generator

(OFF)

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

™

leads
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
signal when connecting both leads of the Turbo Tone

LO amplitude setting may generate a stronger

™

to a cable
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

™

directly to

a wall jack.

To maximize radiated signal while tracing along a cable run,
connect one lead of the Turbo Tone

™

to the wire or cable and
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
Turbo Tone

™

to the ungrounded shield of a coax cable. 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

is powering.

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.
