+In order to save power, the LCD display is disabled by default. It can be reenabled by changing `#define USING_LCD (0)` to `#define USING_LCD (1)` in [src/application/instance.h](src/application/instance.h). When enabled, the LCD will display the range calculated and the address of the TAG/ANCHOR that it ranged with.
