The potentiometer (POT) is used to adjust the transmit power. To adjust the power,
perform the following:
The transmit power is divided into 6 levels (See TRC103 datasheet TXCFG register).
Rotating the POT adjusts the voltage level on the internal A-to-D converter (ADC) of the
microprocessor. The ADC continuously samples the POT for a change and updates the
TX power register if it detects a change in voltage level. Each time the microprocessor
updates the TX register the CMD LED will flash indicating an SPI write.
1. To increase the output power, rotate the slot clockwise with a small tuning tool.
2. To decrease the power, rotate the slot counter clockwise.
