A 10 k resistor is connected with the test point's solder eye. A short lead of wire connects the resistor's other lead with a 3.5 mm chassis terminal in the back of the scanner.

You can use a separate chassis connector or, if you don't want to drill, reuse the existing earphone connector. In that case, the two wires running to the connector have to be taken off and connected directly. One of these wires runs to the loudspeaker.
