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. 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. 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. 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. .Package List:1 x Transmitter1 x Receiver1 x Crocodile Clip Adapter Cables1 x RJ-45 Adapter Cables1 x RJ-11 Adapter Cables1 x User Manual1 x Tool BagNote:1. Can not directly search for cables that have been connected to strong electricity, such as wires at home, otherwise it will cause person injury and equipment damage. 2. Pay attention to thunder protection when using the instrument during thunderstorms, so as to avoid person injury and equipment damage caused by thunder induced by the line. 3. The host LCD screen or the POWER light of the line finder flashes, indicating that the battery voltage is low, please replace the battery. 4. When the product is not used for a long time, please take out the battery to avoid of battery liquid leakage or the battery holder corrosion, resulting in poor contact.
