Slide the switch to any position\nto activate the device. Use the LED indicators to determine the physical\nstatus of the cable. (1) If wiring is correct, the indicator light sequence on\nboth the transmitter and receiver unit will be: 1-2-3-4-5-6-7-8 (G light\nilluminates for shielded cable). (2) The following indicate abnormal\nconnections: ① If one wire (e.g., Cable NO.2) is open-circuited, neither the\nNO.2 indicator on the transmitter nor the receiver will illuminate. ② If\nmultiple wires (3 or more) are disconnected, none of the indicators will\nilluminate. ③ If the cable ends are reversed, e.g., NO.1 and NO.2 swapped, the\ndisplay will be as follows: transmitter: 1-2-3-4-5-6-7-8 \/ receiver:\n2-1-3-4-5-6-7-8 3.QC Press and hold the function key to switch to “QC” mode,\nthen Insert the cable crystal head into the top of the transmitter, if all the\nQC lights on the transmitter are on, it indicates that the crystal head is\ncrimped correctly. FAQs: Q: Why does the receiver keep beeping during network\ncable fault detection? A: If you wish to use the fault detection function,\nplease set the transmitter to “PAIR” mode without turning on the receiver.\nPlease note: when the receiver is on, if you select both “PAIR” and “SCAN” on\nthe transmitter and connect the cable ends to the transmitter and receiver,\nthe receiver will emit a continuous beep, which is a normal phenomenon. Q: Why\ndoes the receiver beep for every wire during tracing? For long-distance\ntracing, set the receiver sensitivity to maximum, then lower it gradually\nuntil the target cable is located. If not reduced, strong nearby signals may\ncause continuous buzzing. To confirm you’ve found the correct cable, please\nset the transmitter to ‘PAIR’ and insert the cable end into the receiver port.\nIf both panels’ LEDs light up, it’s the correct cable.
