Use

Batteries

Open the battery compartments on the back of the tone generator and probe. Insert a 9 V battery in each compartment. Mind the polarity. Close the battery compartments.

RJ11 modular connector

The tone generator includes an RJ11 modular connector (5) that can be used instead of the clip test leads (6) when testing a pair of wires in an RJ11 cable. You can use the RJ11 plug in any of the unit’s operating modes.

Tracing cables (suitable for troubleshooting severed boundary cables)

1. Set the Function switch (1) on the tone generator to the Tone” position. The Tone indicator and Power indicator (2, 3)light up.

2. Disconnect the boundary cable from the base station of your lawnmower. Attach the red toner test lead (6) to the cable connector or exposed wiring on the boundary cable you want to troubleshoot. If the cable is shielded, attach the red probe to the shielding. Connect the black toner test lead (6) to ground.
   Note! If you don’t have a proper ground, you can use a metal rod or screwdriver stuck in the ground as a makeshift ground. Attach the black toner test lead to the rod.

3. Hold the signal probe (7) near an exposed part of the boundary cable close to the lawnmower base station, and press the Test button (10). If you hear a tone from the probe, it means the setup is correct. Adjust the Volume and sensitivity using the slider (8)to prevent feedback and determine how close the signal probe needs 1o be to the boundary cable.

4. Trace along the boundary cable with the probe in your hand. Keep the signal probe (7) close to the cable and press the Test button (10). If the cable is buried, you may need to expose it or press the signal probe into the ground to detect the boundary cable. Begin testing the cable in increments of 50 cm. Once you no longer hear a tone from the probe, you have found the severed part of the boundary cable. Reduce the increments to 10 cm to narrow down the exact location.
   Expose the severed section of the cable and repair it using an extension clip.

Tracing pairs

1. Set the Function switch (1) on the tone generator to the Tone” position The Tone indicator and Power indicator (2, 3) light up.
2. Attach the red toner test lead (6) to one wire and the black toner test lead (6) to the other wire of the pair being traced.
3. Trace along the cable and point the signal probe to the wires. Press the Test button (10). The Power indicator on the probe turns on, and a sound is emitted from the probe if the cable s intact.
4. Move the probe along the wire whilst pressing the Test button until the sound stops. When the sound is no longer heard, you have located the broken wire.

Indentifying telephone line condition and checking polarity

1. Set the Function switch (1) on the tone generator to the “Power” position.
2. Connectthe red test lead (6) to one wire and the black test lead (6) to the other wire of the telephone line being tested.
3. Check the indicators:

Continuity Test

1. Connect the test leads (6) to the wire or device being tested.
2. Set the Function switch (1) on the tone generator to the “Continuity’ position.
3. The Continuity indicator (4) lights up if there is an electrical path between the test leads. The tone generator indicates continuity up to approximately 10 k0. The indicator ight s brighter at a low resistance and less bright at high resistance.

Note! Avoid connecting to circuits carrying AC or DC voltage in continuity test mode to prevent damaging the tone generator.

Maintenance

Keep the tone generator and probe dry. Wipe them with a soft, dry cloth. Avoid using chemicals, detergents or solvents when cleaning the tone generator, probe or the case.
Remove the batteries from the tone generator and/or probe f you are not going to use them for long periods of time.

Safety information

Read the manual fully before using the instrument.
Keep the devices away from moisture, water, high temperatures, and direct and strong sunlight
The tone generator and probe rely on a 9 V battery for power. Do not use alternative means to power the instrument.
In toner and polarity modes, the maximum permissible voltage across the test leads is 60VDC.
Do not connect the instrument to circuits carrying AC voltage while in toner or polarity mode. Do not connect the instrument to circits carrying AC or DC voltage while in continuity mode.
Exercise caution and refrain from touching the metal tips of the test leads when making connections.
Do not use this instrument if there is a risk of thunderstorms.
This product adheres to CE standards: EN61326-1:2013, EN61326-2-22013.
