The operation method of the host is not different. The operation method of the digital line finder is different from that of the analogue line finder. Press and hold the SCAN button for 2 seconds to turn on the line finder, simulating the line finding function, long press for 2 seconds to shut down, no operation for 10 minutes, it will shut down automatically. _x000D_2. After the line finder clicks SCAN and selects the function, there is no need to press the button during the line finding. Press SCAN on the host to enter the finding function, and press Hz to switch to the digital finding frequency L2 mode. The digital finding cannot switch the finding frequency. In order to quickly find the target line, you can first adjust the direction knob of the line finder to the maximum sensitivity, and after finding the vicinity of the target line, adjust the appropriate sensitivity to precisely locate the target line. At this time, the target line can be connected to the RJ45 port of the line finder, and the line alignment light is all on to further confirm that the target is correct. _x000D_3. Digital Line Finding Function: Blue indicator light, using the latest digital line finding technology, the host sends a digital signal, the line finder is tested by accepting the digital signal transmitted from the network line under test and makes a corresponding sound, at this time the blue light is displayed and always on, or vibrates with the blue indicator light flashes at this time. _x000D_4. Analogue Finding Function: Red indicator light, using general analogue finding function, in order to quickly find the target line, you can first turn the finder to the maximum volume, after finding the target line, adjust the appropriate volume to accurately locate the target line. 1Cables Tester: Consists of a signal transmitter, a line finder and the corresponding adapter cable to better help you diagnose network problem. 2Practical Use: Comes with line finding, pairing, line on off and lighting function, and has long transmission distance and clear voice as well. 3Quick Finding: Able to quickly find the desired cable from a large number of harness cables, designed to have high accuracy and easy operation. 4Reliable Work: Adopting the digital line finding technology to achieve accurate digital line finding with little noises, simpler and practical. 5Broad Utility: An reliable tool for finding computer network cables, telecommunication network communication cables, video network cables, etc. 1 x Transmitter 1 x Receiver 1 x Crocodile Clip Adapter Cables 1 x RJ-45 Adapter Cables 1 x RJ-11 Adapter Cables 1 x User Manual 1 x Tool Bag
