Please carefully read the safety instructions and the user manual before using this product. Keep away from children. Use the device only as specified in the user manual.
The kit includes: transmitter, receiver, RJ11 patch cord, RJ45 patch cord, wire with alligator clips, Type-C USB cable, DC cable, earbuds, user manual, and warranty.

Getting started

Transmitter
Shift the three-position switch (1) to the upper position (ON) to turn the transmitter on.
Shift the three-position switch (1) to the middle position (OFF) to turn the transmitter off.
Shift the three-position switch (1) to the lower position (TONE) to switch the transmitter to the Telephone line status test mode.
Receiver
Turn the sensitivity adjustment knob (18) clockwise to turn the receiver on.
Turn the sensitivity adjustment knob (18) counterclockwise to turn the receiver off.
Charging the device
The transmitter and the receiver use rechargeable lithium polymer batteries. Connect the USB-cable to the device and the DC adapter via a USB plug and connect it to the AC power supply to charge the device.

Usage

The default mode is dual: Cable tracing / Wire mapping. Press the SCAN button (20) to switch between these two modes.
When the device is in Cable tracing mode, the SCAN button (20) steadily glows.
When the device is in Wire mapping mode, the SCAN button (20) blinks.
Wire mapping
This function is used to check if the wires within the cable are connected correctly.

Switch the device to Wire mapping mode.
Plug one end of the cable into the RJ45 port (11) on the transmitter and the other end into the RJ45 port (24) on the receiver.

The results are shown with the corresponding LEDs (9, 19). Possible outcomes are shown below:

Normal: The LEDs on the transmitter and on the receiver will blink green one by one.
Transmitter: 1-2-3-4-5-6-7-8
Receiver: 1-2-3-4-5-6-7-8| Short: If pins 2 and 5 are short-circuited, the corresponding LEDs on the transmitter and LEDs on the receiver will have a weak glow.
Transmitter: 1-2-3-4-5-6-7-8
Receiver: 1-2-3-4-5-6-7-8
Transmitter: 1-2-3-4-5-6-7-8
Receiver: 1-2-3-4-5-6-7-8
---|---
Open: If pin 2 is open, the corresponding LEDs on the transmitter and on the receiver will not glow.
Transmitter: 1-x-3-4-5-6-7-8
Receiver: 1-x-3-4-5-6-7-8| Cross: If pins 2 and 5 are cross-connected, the corresponding LEDs on the transmitter and on the receiver will blink in the same manner.
Transmitter: 1-2-3-4-5-6-7-8
Receiver: 1-5-3-4-2-6-7-8

Cable tracing

This function is used to locate the target cable in a cable bundle.
Switch the Cable tracing mode on.
Network cable tracing

Plug the loose end of the network cable into the RJ45 port (11) on the transmitter; the other end is connected to the network equipment (such as a network switch, router, etc.).
Place the receiver near the cable bundle and move the receiver along the cable to trace it. When the sensor is in the close proximity to the target cable, the receiver will emit a beeping sound. To detect the cable more accurately, lower the sensitivity. The closer the device is to the object, the louder the signal will be.

Telephone cable tracing

Plug the loose end of the cable into the RJ11 port (10) on the transmitter; the other cable end is connected to a telephone line.
Place the receiver near the cable bundle and move the receiver along the cable to trace it. When the sensor is in the close proximity to the target cable, the receiver will emit a beeping sound. To detect the cable more accurately, lower the sensitivity. The closer the device is to the object, the louder the signal will be.

Cable crimping quality check
This function is used to check the quality of cable ends crimping for the proper connection of conductors to pins.

Press the QC button (6) to switch to Quality check mode to test cable connectors. When the device is in Quality check mode, the QC button (6) will glow steadily.
Plug one end of the testing cable into the QC port (12) and leave the other cable end disconnected.

Possible outcomes are shown below:

Network cables
If all contacts are normal, all the corresponding LEDs (8) on the transmitter will glow as follows:
1-2-3-4-5-6-7-8
In case of faulty contact, a corresponding LED on the emitter will not glow:
1-x-3-4-5-6-7-8| Telephone cables
If all contacts are normal, all the corresponding LEDs (8) on the transmitter will glow as follows:
RJ-12 (6P6C) normal: x-2-3-4-5-6-7-x
RJ11 (6P4C) normal: x-x-3-4-5-6-x-x
RJ-11 (6P2C) normal: x-x-x-4-5-x-x-x
In case of faulty contact, a corresponding LED on the emitter will not glow.

Port Flash function
This function is used to locate an exact port on a network switch or on a router to which the tested cable is connected.

Press the FLASH button (7) to enter the Port Flash function mode. When the device is in the Port Flash mode, the FLASH button (7) and the Port Flash indicator (3) steadily glow.
Plug one end of the network cable into the RJ45 port (11) on the transmitter, and the other end is connected to the network equipment (such as a network switch, router, etc.).
The Port Flash indicator (3) on the transmitter will flash with the same frequency as the LED of the target port on the network switch/router, and different from the other LEDs.
When a PoE cable is connected, the corresponding Wire mapping / Port Flash indicators (9) will glow to identify the pins that provide power over Ethernet.

Telephone line status test
This function is used to detect the telephone line status.

Shift the three-position switch (1) to the lower position (TONE) to switch the transmitter to the Telephone line status test mode.
Plug the loose end of a telephone into the RJ11 port (10) of the transmitter, the other end of the telephone cable is connected to a telephone line. You can use the wire with the alligator clips, if needed.
If the Telephone line indicator (2) steadily glows, the telephone line is standby.
If the Telephone line indicator (2) blinks green and red, the telephone is ringing.
If the Telephone line indicator (2) dims and goes off, the telephone line is busy.

The indicator light color depends on the polarity of the telephone line.
Polarity test
This function is used to define the polarity of wires.

Shift the three-position switch (1) to the lower position (TONE) to switch the transmitter to the Telephone line status test mode.
Plug the loose end of a telephone into the RJ11 port (10) of the transmitter, the other end of the telephone cable is connected to a telephone line. You can use the wire with the alligator clips, if needed.
If the Telephone line indicator (2) glows green, it means that the telephone line 3P (black clip) is positive, and the telephone wire 4P (red clip) is negative.
If the Telephone line indicator (2) glows red, it means that the telephone line 3P (black clip) is negative, and the telephone wire 4P (red clip) is positive.

Non-contact voltage detection function (NCV)
This function is used to detect voltage without having to touch the cables.
Press the NCV button (21) on the receiver. Hold the sensor (14) up to a wire, socket, or any surface with hidden wiring. If the device detects the voltage above 40V AC, the receiver emits a warning sound. The closer the device is to the object, the louder the signal will be.
