Program ⇒ Fundamental ⇒ Standard Mode Selection ⇒ Command Mode and Frequency Mode 1,
respectively.

Frequency Override. The availability of the Local mode of operation may be reinstated by changing this
setting or performing a Reset (see F007).
ESC Key — The Escape key returns the system to the previous level of the menu tree, toggles between
the EOI Command screen and the Frequency Command screen, or cancels changes made to a field if
pressed while still in the reverse video mode (dark background/light text). The 3 functions are menu-
