 //
-// LCD CHARSET
+// LCD CHARACTER SET
 //
-// Choose ONE of the following charset list, keep in mind that this selection is

-// based LCD you have.
+// Choose ONE of the following charset options. This selection depends on
+// your physical hardware, so it must match your character-based LCD.
 //
-// Note: This options is ignored for a full graphic display.
+// Note: This option is NOT applicable to graphical displays.
 //
-// To find out what type you have:
-//  - Compile and upload with language set to 'test'
-//  - Click to get the menu
+// To find out what type of display you have:
