is pressed. If the “BATTERY GOOD” LED 
does not light, replace the battery. 

6.2 Low Battery Indicator:   

When the “BATTERY LOW” LED light on, 
replace the battery.   

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 intake 
conductors, the “NO CONNECTION” LED 
with light and the beeper will sound once.   

6.4 Connected LED/Lo-Hi Beep /Numbered 

LEDs  

If the “CONNECTED” LED lights and the beeper 
emit a Lo-Hi beep, examine the numbered LEDs 
(i.e. LEDs numbered to 8 and the S LED). 
Corresponding to the type of cable being tested 
must light .Examine the table below the Numbered 
LEDs, noting what LEDs should light .If all of the 
LEDs do not light; the cable has an OPEN fault. If 
all of the appropriate numbered LEDs light, the 
cable is OK.   
Note:  
When testing an RJ-45 UTP cable, the S LED must 
not light. The CABLE SNIFFER-REMOTE 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 cables is expected to contain 8 
conductors. If only 4 conductors are used between 
the RJ-45 connectors. The CABLE 
SNIFFER-REMOTE may not properly identify the 
faults.  
RJ-11 cables may have 2 connections, 4
