5. Impostazione
5.1 Installazione della batteria
- Emettitore: The emitter unit is powered by a rechargeable 3.7V lithium battery. Ensure it is charged using the provided charging cable before first use. The low voltage indicator LED will flash when the battery is below 3.7V.
- Ricevitore: The receiver unit requires one 9V 6LR61 battery. Open the battery compartment on the back of the receiver, insert the 9V battery with correct polarity, and close the compartment. The low voltage indicator LED will flash when the battery is below 9V.
5.2 Cavi di collegamento
- For RJ45/RJ11 Cables: Connect one end of the network or telephone cable directly to the corresponding RJ45 or RJ11 port on the emitter unit.
- For Other Wires: Use the provided alligator clip cable. Connect the alligator clips to the two ends of the wire you wish to trace.
6. Istruzioni per l'uso
6.1 Accensione
Press the power button on both the Emitter and Receiver units to turn them on. Ensure the indicator lights illuminate.
6.2 Wire Tracing (Digital Mode for RJ45/RJ11)
- Connect the RJ45 or RJ11 cable to the emitter's corresponding port.
- Set the emitter to Digital Signal Mode (multifrequency pulse).
- Turn on the receiver and adjust its sensitivity.
- Move the receiver's probe along the suspected path of the cable. The receiver will emit an audible tone and/or illuminate LEDs when it detects the signal. The tone will be strongest directly over the cable.
- For underground cables, the detection depth is up to 2 meters.

Figura 4: The PM6819A receiver unit tracing an underground cable in a garden, indicating a detection range of 23.7 inches (approximately 0.6 meters) for effective localization.
6.3 Wire Tracing (Analog Mode for Other Wires)
- Connect the alligator clips from the emitter to the wire you want to trace.
- Set the emitter to Analog Signal Mode (audio pulse).
- Turn on the receiver and adjust its sensitivity.
- Move the receiver's probe along the suspected path of the wire. The receiver will emit an audible tone, strongest when directly over the wire.
- For analog signals, the detection depth is up to 0.3 meters.
6.4 Prova di continuità
- Connect the emitter to the cable or wire using the appropriate connector (RJ45, RJ11, or alligator clips).
- Activate the continuity test function on the emitter.
- Observe the continuity indicator lights on the emitter. If the resistance value is less than 1KΩ, continuity is confirmed, and the corresponding indicator lights will illuminate. An additional indicator light will operate for every 100Ω, and all lights will be on above 1KΩ.
6.5 Line Finding and Break Detection
The PM6819A can help locate specific lines and identify breaks.
- When tracing a cable, a sudden loss or significant decrease in signal strength from the receiver indicates a potential break in the line.
- The device's ability to detect signals through walls and underground makes it effective for locating hidden wiring.

Figura 5: Illustration of the PM6819A detecting a break in an underground cable. The receiver emits sound ('bibibi~') when a signal is present and no sound when the cable is broken.

Figura 6: The PM6819A's capability to find both underground cables and in-wall wiring, demonstrating its versatility.
7. Manutenzione
- Pulizia: Pulire il dispositivo con un panno asciutto e morbido. Non utilizzare detergenti abrasivi o solventi.
- Sostituzione della batteria: Replace the 9V battery in the receiver when the low voltage indicator flashes. Recharge the emitter's lithium battery as needed.
- Magazzinaggio: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the 9V battery from the receiver.
8. Risoluzione Dei Problemi
- Nessun rilevamento del segnale:
- Ensure both emitter and receiver are powered on.
- Controllare i livelli della batteria in entrambe le unità.
- Verificare che i collegamenti dei cavi siano saldi.
- Increase receiver sensitivity.
- Ensure the emitter is set to the correct signal mode (digital for RJ45/RJ11, analog for other wires).
- Segnale debole:
- Adjust receiver sensitivity.
- Ensure the cable is within the specified detection depth.
- Environmental interference may affect signal strength; try to minimize external noise.
- Emitter Not Charging:
- Controllare il cavo di ricarica e l'adattatore di alimentazione.
- Assicurarsi che la porta di ricarica sia pulita e priva di detriti.
