WIRING
Cable requirements
Use a parallel conductor cable. Coaxial cable should
not be used.
When existing chime wires are used, it is possible that the
wires may contain high voltage current. Locate and remove
the bell transformer before actually connecting
MJ-DS.
Extra pair(s) in the installed cable can affect image quality,
and must be terminated with a 120 ohm resistor at each
end on both MJ-DS and MJ-1AD.
