How do I operate the SOHO RJ-45 and BNC Tone Generator w/ Terminator Storage?

The tester comes with a 6ft jumper bnc cable and a 50ohm bnc female terminator. To test the cable connect one end of the cable to the tester and terminate the end of the cable to the 50ohm bnc female terminator. When the client is used on the tester directly connected to the port on this device the tester will read as open. With the terminator on the cable it will read as pass or fail if the cable is working.
