1.1 Plug one end of the tested cable into the transmitting RJ45 jack on
the master unit marked with a ' ' and the other end of the cable into
the remaining receiving RJ45 jack.
1.2 Slide power switch on. The upper row of LEDs will start to scan in
sequence if the Auto/Manual button is set on "Auto" mode. The
LED for pin 1 will light up if the button is in "Manual" mode.
1.3 Switch back and forth from Auto or Manual scanning mode by
pressing the Auto/Manual button on the side of the master testing
unit.
1.4 Once both ends of the cable are plugged in properly, the second row
of LEDs will illuminate according to the corresponding LEDs in the
top row.
1.5 Read the results of the LED display for the pin configuration status
of the tested cable. If you fail to read the results the first time in
Auto mode, you may wait for the second LED scan, or simply switch
to Manual mode for pin by pin testing. In Manual mode, pressing
the square "Test" button will advance testing to the next pin.
