Remove the three screws securing the KPA3 amplifier module to the shield assembly (see Figure 3).
Figure 3. Removing the KPA3 Screws.
Unplug the KPA3 module from the two multi-pin connectors at the rear edge by placing your thumbs under
the back edge of the KPA3 board near the connectors and placing your fingers on the heat sink to gently move the
opposite edge of the KPA3 up and down (see Figure 4). This will “walk” the connectors apart, freeing the
module.
Your KPA3 module may produce a rattling sound when shaken. This is normal. It is
caused by ferrite beads sliding along wire leads in the module.
