-This is a deep sleep state. It only happens if the board is not charging, otherwise the board enters a light sleep state with no indicators.
+This is a deep sleep state. There are no indicators in other sleep modes.
 - Bluetooth connection indicators will be lit blue when establishing connection. This lights the corresponding
 BT mode key. No indicator for RF as the sidelight is a different colour.
 - Default startup LED brightness set to zero and side led set to lowest brightness. This is because I don't use LEDs so I don't need to toggle them off when resetting the board or flashing new firmware.
