AUTION
:
The AP20 and AP24 audio processors contain parts that are static sensitive. Use caution when
handling to avoid damage and avoid touching circuit boards.
When removing or installing internal cables, keeping one hand on the chassis will help to ground you with
respect to internal circuitry.
It is a good idea to stand on a linoleum or cement fl oor (not carpet) when handling the processor.
Installation from A to Z
1. Find a suitable workspace to perform the procedure. Antistatic foam or an antistatic mat is an ideal work surface.
2. Turn off the processor’s rear panel power switch and unplug the power cord.
3. Remove the top cover. See "Remove the top cover", page 2
