3. Test button 7. Red and black test leads C. Volume control

4. Speaker 8. 4 conductor modular cord and plug

• Overall instructions:

1. Connecting the tone generator.

In terminated working cables: Connect one test lead to a terminated wire and the other test lead to an earth or equipment ground. In unterminated or non-working cables: Connect one test lead to an unterminated wire and the other test lead to another unterminated wire.

2. Depress the round on/off button of the amplifier probe. The volume control switch can be

adjusted to suit the environment. Volume can be increased to overcome noise, or decreased to reduce interference.3

3. Touch the tip of the amplifier probe to the insulation of each suspect conductor.

4. Reception of the tone will be loudest on the subject wire.

5. The plug receptacle is provided to be connected to a headset or handset.

• Identifying tip and ring (switch to “Off”):

1. Connect the RED test lead to one line and the BLACK lead to the other line.

2. The LED will glow GREEN when you connect the RED test lead to the RING SIDE of the line.

3. The LED will glow “RED” when you connect the RED test lead to the TIP SIDE of the line.

• Identifying line condition (switch to “OFF”):

1. Connect the RED test lead to the RING SIDE of the line and the BLACK lead to the TIP.

a. A bright green LED indicates a clear line b. No light indicates a busy line c. A brightly flickering YELLOW light indicates a RINGING line

• Verifying lines (switch to “OFF” then “CONT”):

1. Dial the line to be verified.

2. While the line is ringing, connect the RED lead to the RING SIDE of the line and the BLACK

3. In the “Off” position, the indicator light will flicker YELLOW when the test leads are connected to

4. If you switch the test set to “CONT”, it will terminate the call on the subject line.

• Sending tone (switch to “TONE”): (Caution: Do not connect to an active AC circuit exceeding 24V in this mode)

1. Connect the test leads to the pair, or attach one lead to ground and one lead to either side of the

2. A dual alternating tone, or a single solid tone, can be selected from the switch inside the tone

3. Probe the suspected wires with the amplifier probe. Reception of the tone will be strongest on

the subject wire. In the case of ready access to bare conductors, a handset or headset may be used to receive the tone.

• Testing continuity (switch to “CONT”): (Caution: Do not connect to an active AC or DC circuit in this mode)

1. Connect the test leads to the subject pair.

2. Use “CONT” position.

3. A bright GREEN light indicates continuity. The LED will not glow if the line resistance exceeds

• Testing continuity using tone (switch to “TONE”): (Caution: Do not connect to an active AC or DC circuit in this mode)

1. Connect the test leads to the subject pair.

2. Use a handset or headset at the remote end and touch the wire end(s) with the clip lead(s).

3. Reception of the tone is an indication of continuity.

1. All of the above tests are available through the modular plug for line 1 only – red and green

1. To test unterminated coax, connect the red lead to the outer shield and the black lead to the

centre conductor or the red lead to the outer shield and the black lead to the ground.

2. To test the terminated coax, connect the red lead to the connector housing and the black lead to

the centre pin or the red lead to the connector housing and the black lead to the ground.
