   - [[https://github.com/ok1hra/k3ng_rotator_controller/blob/master/k3ng_rotator_controller/rotator_language.h#L22|Azimuth shorts]] you can replace with prefixes which are in the same direction from your QTH. For example see [[https://github.com/ok1hra/k3ng_rotator_controller/blob/master/k3ng_rotator_controller/rotator_language.h#L126|prefixes from OK]].
   - And [[https://github.com/ok1hra/k3ng_rotator_controller/blob/master/k3ng_rotator_controller/rotator_language.h#L13|Azimuth]] you can replace with **name your antenna or tower**, e.g. //20m YAGI//.
+  -  If do not show degree character (°), change in file rotator_settings.h settings to<code>#define DISPLAY_DEGREES_STRING "\xB2"</code> If the LCD displays instead of the character degree (°) lower case **"alpha" (α),** find in source code all string **'char(223)'** and replace to **'char(178)'**.
