3.5 Check breakage location of  non-energized wires (as below)
Connect  a  broken  wires with the two clips, push the key to “scan”, 
Keep the probe close to wire, it means normal if “beep” emits. Then 
move the probe  along the wire, the point is breakage when no “beep”
comes out. 

Note:
1) clip one core with red clamp, keep the black one free.
2)turn the volume to degree 6-8 when tracing cable.
3)Clip one core to tested. 

3.6 Network cable  mapping             
3.6.1)  If the tested cable is in good connection, No.1-8 &G leds  will 
be on and blink in circulation. 
3.6.2)  If No. 2 & No.3 cables are broken, the No.2 led of emitter and
