Plug one end of the cable into the appropriate jack on the left side panel of the CT-6.
Plug the other end of the cable into the appropriate jack on the right side panel. Set the
rotary switch to “1” to test the connection of contact 1 on the plug inserted into the left
side panel.
If there is a connection, the Green LED will light below “1” and a Yellow LED will light
above each contact on the right side plug connected to “1” on the left side plug. Use the
charts below to verify proper cable connections.
If no LED lights than there is no connection and the left side contact “1” is “floating” due
to design or an “open” in the cable.
Set the rotary switch to “2” to test contact 2, and so on, until all contacts have been
checked.
