4. Compoñentes Overview
4.1 Fox HotWire Tone Generator
The Fox HotWire is the transmitter unit. It generates a signal (tone) that is injected into the wire to be traced. Key features include:
- Varios tons: Generates Pulse or Warble tones.
- Proba de continuidade: Visual and audible indication.
- TrueTrace & TripLatch Tests: Proprietary tracing and latching functions.
- Protección contra sobrecarga: Up to 250 VAC.
- Opcións de enerxía: Can be powered by a 9-volt battery or the high voltage line it is toning.
- Parte traseira magnética: Allows for hands-free operation by attaching to metal surfaces.

4.2 Hound HotWire Inductive Ampmáis vivo
The Hound HotWire is the receiver unit, used to detect the tone generated by the Fox HotWire. Key features include:
- Sensibilidade axustable: Thumbwheel control for precise signal detection.
- Indicador de intensidade do sinal: LED provides visual feedback.
- Built-in LED Headlight: Illuminates dark work areas and helps reduce fluorescent light noise.
- Filtro de paso de banda: Suppresses unwanted frequencies for clearer signal detection.
- Conector para auriculares: For use in noisy or quiet environments.
- Easy Access Battery Cover: For convenient battery replacement.

5. Configuración
5.1 Instalación da batería
Both the Fox HotWire and Hound HotWire require one 9V battery each. To install:
- Localice o compartimento da batería na parte traseira de cada unidade.
- Abra a tapa da batería.
- Connect a 9V battery to the battery clip, observing correct polarity.
- Coloque a batería no compartimento e peche a tapa con seguridade.
Nota: The Fox HotWire can also be powered by the live circuit it is tracing, but a 9V battery is required for low voltage tracing and continuity tests.
5.2 Comprobación inicial
Before use, perform a quick check:
- Ensure batteries are installed in both units.
- On the Fox HotWire, press the UNLOCK button and set the switch to 'TRACER TONE'.
- Set the RF LEVEL knob to midrange.
- On the Hound HotWire, set the sensitivity thumbwheel to midrange and press the 'PUSH ON' button.
- Bring the tip of the Hound near the test leads of the Fox. You should hear an audible tone and see the signal strength LED illuminate.
6. Instrucións de funcionamento
6.1 Tracing Live Circuits (120VAC/220VAC)
The HotWire kit is designed to safely trace live AC circuits up to 250VAC.
- Connect the Fox HotWire to the live circuit. For an outlet, use the provided test leads with flat blades or pointed probes. Ensure a secure connection. The 'VOLTAGE PRESENT' LED on the Fox will illuminate.
- Set the Fox HotWire switch to 'TRACER TONE' and select either 'PULSE' or 'WARBLE' tone.
- Adjust the RF LEVEL knob on the Fox to an appropriate setting.
- Activate the Hound HotWire by setting its sensitivity to midrange and pressing 'PUSH ON'.
- Move the tip of the Hound along the suspected path of the wire. The signal strength LED and audible tone will indicate the wire's location.
- Adjust the Hound's sensitivity as needed to pinpoint the wire. A lower sensitivity setting helps in isolating a specific wire in a bundle.

6.2 Tracing Unpowered Wires
For unpowered wires (e.g., telephone, LAN, security, or de-energized electrical circuits):
- Ensure the circuit is completely de-energized.
- Connect the Fox HotWire test leads to the wire pair or single wire to be traced. For a single wire, connect one lead to the wire and the other to a good ground.
- Set the Fox HotWire switch to 'TRACER TONE' and select a tone.
- Use the Hound HotWire as described in Section 6.1 to trace the wire.
6.3 Tracing Through Building Materials
The HotWire's RF signal can penetrate various building materials.
- Drywall, Plaster, Wood, Cement: The Hound can detect signals through these materials. Move the Hound slowly and adjust sensitivity to find the strongest signal.
- Metal Conduit: The TrueTrace feature on the Fox HotWire allows the RF signal to be sensed through most metal conduits.

6.4 Tracing Underground Wires
The HotWire can trace shallow underground wires up to 6 inches deep, such as those for 'Invisible Fences', cable television, telephone, or low voltage iluminación da paisaxe.
- Connect the Fox HotWire to the underground wire. Ensure the other end of the wire is either open or grounded, depending on the tracing method.
- Set the Fox HotWire to 'TRACER TONE'.
- Walk along the suspected path of the underground wire with the Hound HotWire held close to the ground.
- Adjust sensitivity to locate the strongest signal, indicating the wire's path.

6.5 Proba de continuidade
The Fox HotWire can perform a visual and audible continuity test.
- Set the Fox HotWire switch to 'CONTINUITY'.
- Connect the test leads across the circuit or wire to be tested.
- An audible tone and visual indicator will confirm continuity.
7. Mantemento
7.1 Substitución da batería
Replace the 9V batteries in both the Fox and Hound units when the battery test indicator shows low power or when the units do not function correctly.
- Abra a tapa do compartimento da batería.
- Disconnect the old battery and replace it with a new 9V alkaline battery.
- Pecha a tapa da batería de forma segura.
7.2 Limpeza
