It is suitable for tracking RJ45 internet cable, RJ11 telephone line and other metal wire in low electricity. Please note that it can not be used to track wires with high electricity ( maximum currents for emitter and receiver are 10mA and 30mA respectively, and maximum voltage is 10V ). Besides, you may need two 9V laminated cells, which are NOT included in the packaging of this item.Network Cables Verifying. Plug one side of the cable into the emitter and the other side into the receiver. Select "Network" to check and verify whether the network cables are good or not. No need of network tester.Wire Tracking. It can trace not only Ethernet LAN wires, but also electrical and speaker wires when connecting to the alligator clip.

Adjust the volume knob to make the volume proper and avoid being interfered. At night or in a dark environment, you can turn on the illuminating lamp, which can be helpful during operating.Operating temperature: 0-40 degrees Celsius, maximal 80 percent relative humidity (non-condensing)Storage temperature: -10 -50 degrees Celsius, maximal 80 percent relative humidity (non-condensing)Altitude: less than 2000mAnti-explosion rating: IP40Distance of emitting signal: 300m or soEmitter battery: 6F 22/9V (not included)Receiver battery: 6F 22/9V (not included)Use a standard 9V alkaline product battery or 9V charging battery
