5. Setup

Before using the NF-816, ensure batteries are properly installed.

5.1 Battery Installation

Both the transmitter and receiver require 9V batteries (not included). To install:

1. Locate the battery compartment on the back of each unit.
2. Open the battery cover.
3. Insert a 9V battery, ensuring correct polarity (+/-).
4. Close the battery cover securely.

5.2 Initial Power On

After installing batteries:

1. For the transmitter, hold the power button for at least 3 seconds to turn it on.
2. For the receiver, slide the ON/OFF switch to the 'ON' position.
3. The Power LED on both units should illuminate.

6. Operating Instructions

The NF-816 is designed to locate single-strand or double-strand wires in parallel. It is not suitable for multi-strand wires.

6.1 Basic Wire Locating Procedure

1. Prepare the Wire: Ensure the wire to be detected is non-energized (power is off).
2. Connect Transmitter: Connect the red alligator clip of the transmitter to the wire you want to trace. The black alligator clip does not need to be connected to anything for basic tracing, but can be grounded for improved performance in some scenarios.

3. Turn on Transmitter: Set the transmitter's switch to 'Cable Scan'. The Status LED should indicate signal transmission.
4. Turn on Receiver: Turn on the receiver and adjust the thumb wheel switch to increase the volume/sensitivity.
5. Trace the Wire: Slowly move the receiver's antenna probe along the suspected path of the buried wire. The receiver will emit a louder sound (beeps) when it is directly over the wire.

6.2 Locating Break-Points

To find a break in a wire:

1. Follow the wire as described above.
2. The signal from the receiver will abruptly stop or significantly weaken at the point of the break.

6.3 Using Earphones and LED Flashlight

• Earphones: For noisy environments, plug the included earphones into the receiver's earphone jack. This allows for clearer detection of the signal.
