Specification: Weight: Approx. 115g / 4.1oz Size: Approx. 10.5 * 9.8 * 2.8cm / 4.1 * 3.9 * 1.1in Instructions: 1. Testing double twisted cables 1,2,3,4,5,6,7,8 and G corresponding ,and tell users which exact line is on wrong circuit. 2. Switch ON is the normal test speed, "S" is the rapid test speed, and OFF is Turn off the Tester. 3.Turn on the tester, insert the line connector into main tester and remote control. Then the indication lights(1 to G) will flash Main tester:                1-2-3-4-5-6-7-8-G Remote control tester: 1-2-3-4-5-6-7-8-G（RJ45）                                      1-2-3-4-5-6------   （RJ12）                                      1-2-3-4----------    （RJ11) If the connection is not normal, it will be displayed as follows: 1.When there is a network cable such as NO. 3 cable is open circuit, the main tester and remote test end NO.3 lights is not on. 2.When several cables are open circuit, several cables are not on. When less than two cables are connected, the lights are not on. 3.When the two ends of network cables are in disorder, for example, cable 2 and 4 are in disorder, it is shown as follows: Main tester unchanged: 1-2-3-4-5-6-7-8-G Remote tester: 1-4-3-2-5-6-7-8-G 4. When there are two wires short circuits, the main tester does not light up, while the remote test end shows that both of the two line lights of short circuit are dim. If there are more than 3 (including 3) short circuits, all the lights of several wires Numbers of short circuit will not light up. Package list: 1 * Network Cable Tester  Package List
