CUSTOMIZING INTERNAL JUMPERS
If your radio is not listed above, you can create a custom jumper position table.
Begin by removing the screws from the sides of the cabinet. Lift the cover off.
Look from the front view and notice the group of pins and black jumpers on the
left side behind the microphone connector and in front of the microphone output
jack. Fill in a custom table like the following:

UNLISTED RADIOS
To make a jumper table for an unlisted radio, you must look at the radio manual.
Find the page that shows the microphone wiring. This is a sample of a Yaesu-
style wiring diagram that was used above:

If you compare table 1 to this connector diagram, you will see how it is laid out.
Notice an “X” was placed at the appropriate PTT and MIC pins according to the
rules below.
Look at the microphone-wiring diagram in your radio manual, fill in a table, and
connect the leads as we have done in our example. We have provided a blank
chart below for you to fill in.
