Setup

1. Charge Batteries: Ensure both the transmitter and receiver are fully charged using the provided Type-C charging cable. The devices are powered by rechargeable 3.7V 1500mAh lithium batteries.
2. Power On: Turn on both the transmitter and receiver using their respective ON/OFF buttons.
3. Initial Check: Perform a quick function check to ensure both units are operational before field use.

Operating Instructions

1. Locating Cable Breakpoints and Tracing Cable Routes

This procedure is used to find breaks in buried or hidden cables and to trace their path.

1. Prepare Transmitter: Set the transmitter to "SCAN" mode.
2. Connect Transmitter: Connect the red alligator clip of the transmitter to the exposed end of the target wire. Connect the black alligator clip to a separate ground point (e.g., a metal rod driven into the earth).
3. Prepare Receiver: Turn the receiver on. Adjust the receiver's sensitivity knob (thumb wheel switch) to fine-tune the signal based on cable length and environmental conditions.
4. Trace the Cable: Sweep the receiver approximately 3-4 meters (10-15 feet) away from the transmitter. Move the receiver along the suspected path of the cable.
5. Identify Signal: The receiver will emit a beeping tone. The tone becomes fastest and strongest directly above the cable and fades as you move away from its path.
6. Locate Breakpoint: Follow the tone. The point where the sound abruptly disappears or significantly weakens indicates the exact breakpoint in the cable.

2. Short Circuit & Continuity Diagnosis

This function allows for a quick check of continuity and short circuits in wires.

1. Connect Clips: Connect both the red and black alligator clips of the transmitter to the two wires under test.
2. Observe Indicator:
   • If a short circuit exists between the two wires, the Short Circuit Indicator on the transmitter will light up red.
   • If the wires are continuous (no short circuit), the indicator will remain off.

3. LED Flashlight Function

The receiver is equipped with a built-in LED flashlight for use in low-light conditions.

• Activate Flashlight: Press the ON/OFF/Lamp button on the receiver to turn the LED flashlight on or off.
• This feature is useful for illuminating dark attics, basements, or for outdoor night work.
