7.6.3 No connection LED/Single Beep

If the Remote is not connected to the Main unit with a cable, 
or the cable has no intact conductors, the No Connection 
LED will light and the Beeper will sound Once. 

Note:

When testing an RJ-45 UTP cable. The S/G LED must not light.
When testing an RJ-45 UTP cable. The S/G must light.

The 4 in 1 is intended to test complete cables. It may not find 
faults in cables that are intentionally incomplete. For example, 
the standard EIA/TIA 568 RJ-45 terminated Ethernet cable is 
expected to contain 8 conductors. If only 4 conductors are 
used between the RJ-45 connectors, the 4 in 1 may not 
properly identify the faults. 

RJ-11 cables may have 2 connections, 4 connections, or as many 
as 6 connections .For 2 connection cables, LED 3 and  4 must 
light . For 4 connection cables, LED 2, 3,4 and 5 must light. For 6 
connection cables, LED 1,2,3,4,5 and 6 must light.
