How to use
Connect one end of the cable to the main unit and the other end to the remote terminator or plug into the target jack. Power on the tester and observe the LED sequence or indicators to determine continuity and pair wiring order. For RJ45 cables, check that all eight conductors light in the correct sequence; for RJ11, verify the relevant conductor pairings. Turn the device off after testing to conserve battery life.
