Reading the screen: cyan is a value you entered, green is a computed result, amber means a field still needs input or the entry needs a CHECK. SOLVED lights when every result is computed; STO keeps a value to reuse in another function; the line-select keys beside the screen pick the field the keypad edits.
How this is computed
True → magnetic → compass. Variation is signed East-positive ("east is least": magnetic = true − variation); deviation is the signed correction from your aircraft's compass card, added to magnetic as the ASA CX-3 manual's worked example applies it (203 T with 4° W variation and 4 deviation → 207 M, 211 C). Check the card placarded in YOUR airplane — deviation is aircraft- and heading-specific.
