How to use
Connect one end of the network cable to the main unit and the other end to the remote unit or outlet under test, then power on the tester. Observe the LED indicators to determine whether pairs are correctly connected, swapped, shorted or open. Use the remote unit to test installed wall outlets and long cable runs; use the main unit alone for short patch cable checks. Follow standard safety precautions when testing in live network environments and ensure the cable is disconnected from active equipment if necessary.

For reliable results, test cables with both ends accessible and ensure connectors are fully inserted. When troubleshooting, isolate the cable from powered network devices to avoid misleading indications. Store the tester in a dry, dust-free environment and check batteries before use to maintain consistent operation.
