4. Komponenter 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:
- Flere toner: Generates Pulse or Warble tones.
- Kontinuitetstest: Visual and audible indication.
- TrueTrace & TripLatch Tests: Proprietary tracing and latching functions.
- Overbelastningsbeskyttelse: Up to 250 VAC.
- Strømindstillinger: Can be powered by a 9-volt battery or the high voltage line it is toning.
- Magnetisk bagside: Allows for hands-free operation by attaching to metal surfaces.

4.2 Hound HotWire Inductive Amplivligere
The Hound HotWire is the receiver unit, used to detect the tone generated by the Fox HotWire. Key features include:
- Justerbar følsomhed: Thumbwheel control for precise signal detection.
- Signalstyrkeindikator: LED provides visual feedback.
- Built-in LED Headlight: Illuminates dark work areas and helps reduce fluorescent light noise.
- Bandpass Filter: Suppresses unwanted frequencies for clearer signal detection.
- Stik til øretelefoner: For use in noisy or quiet environments.
- Easy Access Battery Cover: For convenient battery replacement.

5. Opsætning
5.1 Batteriinstallation
Both the Fox HotWire and Hound HotWire require one 9V battery each. To install:
- Locate the battery compartment on the back of each unit.
- Åbn batteridækslet.
- Connect a 9V battery to the battery clip, observing correct polarity.
- Placer batteriet i batterirummet, og luk dækslet forsvarligt.
Note: 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 Indledende kontrol
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. Betjeningsvejledning
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 landskabsbelysning.
- 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 Kontinuitetstest
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. Vedligeholdelse
7.1 Udskiftning af batteri
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.
- Åbn batterirummets dæksel.
- Disconnect the old battery and replace it with a new 9V alkaline battery.
- Luk batteridækslet forsvarligt.
7.2 Rengøring
Clean the units with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the units are dry before storage or use.
