So the LCD can either run directly from the battery or from a charge pump internal the CC430. I think we've been running directly from the battery, in which case we should either abandon C4 from the BOM or enable to charge pump to provide better contrast.
Close this issue when we understand the charge pumps and voltage selection, and have either rejected C4 or enabled the CC430's LCD charge pump.
