3. Nastavení a příprava
3.1 Nabíjení zařízení
The NF-816L features built-in rechargeable lithium batteries. Before first use, ensure both the transmitter and receiver units are fully charged using the provided Type-C charging cable.

3.2 Připojení vysílače
To prepare for tracing, connect the transmitter unit to the wire you intend to locate:
- Ensure the target wire is NOT energized. This is crucial for safety and to prevent damage to the device.
- Connect one of the alligator clips (typically red) from the transmitter to the wire you want to trace.
- Connect the other alligator clip (typically black) to a good ground source. This can be a metal stake driven into the ground, a metal water pipe, or another suitable grounding point. A proper ground connection is essential for effective tracing.

4. Návod k obsluze
4.1 Základní trasování vodičů
- After connecting the transmitter, turn on both the transmitter and receiver units.
- Hold the receiver unit with the antenna pointing towards the ground, moving it slowly along the suspected path of the buried wire.
- Listen for the signal through the receiver's speaker or the optional earphone. The signal will be strongest directly over the wire.
- Adjust the sensitivity (thumb wheel switch) on the receiver as needed to refine the signal and pinpoint the wire's exact location. Higher sensitivity is for deeper wires or weaker signals; lower sensitivity helps narrow down the location.
- Mark the path of the wire as you trace it.

4.2 Locating Cable Breaks
Jak najít přerušení drátu:
- Follow the basic wire tracing procedure.
- As you move along the wire's path, pay close attention to the signal strength.
- A sudden drop or complete loss of signal indicates a potential break in the wire. Pinpoint the exact spot where the signal disappears.
4.3 Používání LED svítilny
The receiver unit is equipped with an LED flashlight for use in low-light conditions. Press the "Push for Light" button on the receiver to activate or deactivate the flashlight.

5. Aplikace
The NOYAFA NF-816L is versatile and can be used in various scenarios:
- Pet Fences: Locating buried wires for invisible pet containment systems.
- Electrical Wires: Tracing non-energized electrical lines in walls or underground.
- Síťové kabely: Identifying buried network or communication cables.
- Irrigation Systems: Locating buried sprinkler control wires.
- Venkovní osvětlení: Tracing low-voltage landscape lighting wires.
- Metal Pipes: Can also be used to trace certain metal pipes.

6. Údržba
- Čištění: Otřete jednotky suchým, měkkým hadříkem. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
- Skladování: Přístroj skladujte na chladném a suchém místě, mimo dosah přímého slunečního záření a extrémních teplot.
- Péče o baterie: To prolong battery life, recharge the units regularly, even if not in frequent use. Avoid completely draining the battery for extended periods.
7. Řešení problémů
- Žádný signál nebo slabý signál:
- Ujistěte se, že jsou vysílač i přijímač zapnuté.
- Zkontrolujte stav baterie a v případě potřeby ji dobijte.
- Verify that the target wire is not energized.
- Confirm proper connection of the transmitter to the wire and a good ground source.
- Adjust the sensitivity on the receiver.
- Environmental factors (e.g., very wet soil, metallic interference) can affect signal strength. Try moving slowly and adjusting sensitivity.
- Nepřesná poloha:
- Ujistěte se, že je uzemnění pevné.
- Move the receiver slowly and methodically.
- Reduce receiver sensitivity to narrow down the signal peak.
- Be aware that detection depth and accuracy can be influenced by soil composition and moisture content.
- Zařízení se nezapíná:
- Plně nabijte jednotku.
- Ujistěte se, že je vypínač v poloze „ON“.
