Navigating through RPN sub-menus
Start with the keystroke combination „°, then press the appropriate soft-
menu key (e.g.,
@)@MEM@@ ). If you want to access a sub-menu within this sub-menu
(e.g., @)@DIR@@ within the @)@MEM@@ sub-menu), press the corresponding key. To move
up in a sub-menu, press the L key until you find either the reference to the
upper sub-menu (e.g.,
@)@MEM@@ within the @)@DIR@@ sub-menu) or to the PRG menu
(i.e., @)@PRG@@ ).
