2. Setup
2.1 Battery Installation
The NF-801B Emitter and Receiver units each require one 9V battery for operation. To install the batteries:
- Locate the battery compartment cover on the back of each unit.
- Slide or unclip the cover to open the compartment.
- Insert a 9V battery, ensuring correct polarity (+ and - terminals).
- Close the battery compartment cover securely.
2.2 Unit Overview
Familiarize yourself with the different parts and indicators of the NF-801B units:

3. Operating Instructions
3.1 Network Cable Continuity Test (Wire Map for RJ45)
This function allows you to verify the wiring sequence and continuity of RJ45 network cables.
- Connect one end of the RJ45 network cable to the RJ45 port on the Emitter unit.
- Connect the other end of the RJ45 network cable to the RJ45 port on the Receiver unit.
- On the Emitter unit, slide the function switch to the "TEST" position.
- Observe the LED lights (1-8 and G) on both the Emitter and Receiver units. For a correctly wired cable, the lights will illuminate sequentially from 1 to 8 on both units. The "G" light indicates a shielded cable.
- Any discrepancy in the sequence or unlit LEDs indicates a wiring fault (e.g., open circuit, short circuit, cross-over).

3.2 Wire Finding (Tone Generator Function)
This function helps locate specific cables among bundles or within walls, applicable for RJ11, RJ45, and metal cables.
- Connect the cable you wish to trace to the appropriate port on the Emitter unit (RJ11 for telephone, RJ45 for network, or alligator clips for metal wires).
- On the Emitter unit, slide the function switch to the "SCAN" position.
- Take the Receiver unit and move its probe along the suspected path of the cable.
- Listen for the audible tone emitted by the Receiver. The tone will be strongest when the probe is directly over the target cable.
- For noisy environments, plug the included earphones into the Receiver's headphone jack.
- The Receiver also features a built-in flashlight for working in dark areas.

3.3 POE Switch Test & Live Line Hunting
The NF-801B can assist in identifying POE (Power over Ethernet) switch power supply cores and tracing live POE lines.
- Connect the Emitter unit to the network cable connected to the POE switch.
- Set the Emitter to "SCAN" mode.
- Use the Receiver unit's probe to trace the network cables connected to the switch. The device is designed to withstand up to 60V, preventing damage during live line testing.
- The Receiver will emit a distinct tone when it detects the signal from the target POE line. Adjust the volume for precise identification.

4. Maintenance
4.1 Cleaning
To ensure optimal performance and longevity of your NF-801B, keep the units clean. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
4.2 Storage
When not in use, store the NF-801B and its accessories in the provided tool kit in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries if the device will not be used for an extended period to prevent leakage.
4.3 Battery Replacement
Replace the 9V batteries in both the Emitter and Receiver units when the low battery indicator activates or if the device's performance degrades. Refer to Section 2.1 for battery installation instructions.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace with fresh 9V batteries. |
| No signal or weak signal during wire tracing. | Incorrect mode selected, cable not properly connected, or target cable too far/shielded. | Ensure Emitter is in "SCAN" mode. Verify cable connections. Adjust Receiver volume. For shielded cables, ensure the G light is active. |
| Incorrect wire map results (LEDs not sequential or missing). | Faulty cable (open, short, cross-over) or damaged RJ45 connectors. | Inspect cable and connectors for damage. Re-crimp connectors if necessary. Replace faulty cable. |
| Interference from other cables or devices. | High electromagnetic interference in the environment. | Use earphones for clearer signal. Adjust Receiver volume to minimize background noise. |
