The Control Panel
Keys work differently according to which “mode” is active.
Hold down the CHR PITCH key and press the PRINT SPEED key to
enter Menu mode; repeat the sequence to exit Menu mode. In Menu
mode use the purple text labels underneath the keys to identify the
function of each key.
The lights above these key labels show which option in the list is
active. For example, if both of the CHR PITCH lights are lit, then 15
CPI is the current character pitch; if both lights are ashing, then
PROP (proportional) is the current pitch.
