Setup

Battery Installation:
Locate the battery compartments on both the Emitter and Receiver units. Insert one 9V battery (NEDA 1604/6F22) into each unit, ensuring correct polarity. Close the battery covers securely.
Note: The device includes a low voltage alarm function. If the "L line order led" twinkles, it indicates that the battery needs to be replaced.
Connecting Cables:
Depending on the test you wish to perform, connect the appropriate cable (RJ45, RJ11, or alligator clips) to the Emitter unit. Ensure the cable is securely plugged into the correct port.
Connecting an RJ11 cable and alligator clips to the emitter.

Operating Instructions

1. Cable Continuity Test (Wiremap)

Connect one end of the LAN cable (RJ45) or telephone cable (RJ11) to the corresponding port on the Emitter unit.
Connect the other end of the cable to the RJ45 port on the Receiver unit.
On the Emitter unit, set the Function Switchover Button to "TEST".
Observe the LED lights (1-8) on both the Emitter and Receiver units. They will light up sequentially, indicating the wiremap.
A correct sequence (e.g., 1-1, 2-2, etc.) indicates proper continuity. Any skipped, dim, or incorrectly lit LEDs indicate a fault (open, short, or cross).

The NF-806 can diagnose breakage, open circuits, short circuits, and crossed wires by observing the pin-to-pin cable map indicated by the LEDs.

2. Cable Tracing (Scanning)

Connect one end of the cable you wish to trace to the appropriate port (RJ45, RJ11, or alligator clips) on the Emitter unit.
On the Emitter unit, set the Function Switchover Button to "SCAN". This will generate an audible tone.
Take the Receiver unit and press the "PUSH TO TEST" button.
Move the tip of the Receiver unit along the suspected cables. The loudest tone will indicate the target cable.
Use the Volume Control on the Receiver to adjust the sensitivity and the Inching Button for precise localization.
If working in a noisy environment, plug the earphone into the Earphone Jack on the Receiver unit.
For dark areas, use the Spotlight Switch on the Receiver unit to illuminate your workspace.

Maintenance

Battery Replacement: When the "L line order led" on the Emitter unit twinkles, it indicates low battery voltage (below 6V). Replace the 9V battery in both the Emitter and Receiver units to ensure accurate readings and proper operation.
Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
Storage: Store the device in its carrying pouch in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
Avoid High Voltage: Never connect the device to live high-voltage lines to prevent damage to the unit and potential injury.

Troubleshooting

Problem	Possible Cause	Solution
No power/Unit does not turn on	Dead or incorrectly installed battery.	Replace the 9V battery, ensuring correct polarity.
"L line order led" twinkling	Low battery voltage (below 6V).	Replace the 9V battery in the Emitter unit.
No signal during tracing	Emitter not in SCAN mode, cable not connected properly, or receiver too far from cable.	Ensure Emitter is in SCAN mode. Check cable connections. Move receiver closer to the cable. Adjust receiver volume.
Incorrect wiremap results	Cable fault (open, short, cross) or incorrect cable type selected.	Verify the cable is correctly terminated. Ensure the Function Switchover Button is set to "TEST" for wiremap. The device indicates the specific fault.
Device damaged after connection	Connected to high voltage lines.	WARNING: Do not connect to live high-voltage lines. This device is for low-voltage cable testing only. Damage from high voltage is not covered by warranty.

User Tips

For best results when tracing cables in a dense bundle, try to isolate the cable as much as possible.
Always use the provided earphones in noisy environments to clearly hear the tracing tone.
Utilize the built-in LED light on the receiver when working in dimly lit areas, such as inside server racks or under desks.
Before performing any test, double-check that the cable is properly connected to the correct port on both the emitter and receiver.
Keep spare 9V batteries on hand, especially for prolonged use, as the low voltage alarm indicates imminent battery depletion.
