How to get voltage measurements for internal components
For some tests it is necessary to get access to pins on the power PCB in order to measure voltage.
The pins for the following components are behind the DSP PCB. Use extended thin meter points to
measure voltage on these pins. Refer to Get the necessary test equipment on page 16.
