The Controller Board is a very delicate component and should only be handled as described in this article.
Important:
- Always hold the Controller Board by its edges when handling it.
- Only remove the replacement board from its antistatic bag when you are ready to install it.
- Handle leads and connectors with care. Never try to remove a connector by pulling on its wires. Always try to grip the connector during removal.
Step 1:
Unplug the USB and power leads from the Emblaser 2.
