(1) Note that the use of the function keys along the top of the terminal have a different meaning when
used to change the EPU parameters as opposed to the HHT internal parameters.
(2) Paragraph 6a above explained editing the parameters of the HHT. There, the user is interacting with
the CPU in the HHT. Here, the HHT is transmitting keystrokes directly to the EPU, and likewise
displaying any characters transmitted from the EPU.
(3) Typically, F1 and F2 are the primary menu selection keys used for the EPU menus. The center
function key, F3, is used to exit most operations. F4 and F5 are used to either move a cursor
backward and forward respectively, or to move backward and forward in a parameter list. The F4 and
F5 keys are located above the keys "<" and ">". When space permits on the display of the HHT, the
use of the function keys is listed.
(4) The hand held terminal's function is to enable the user to change the system parameters in the EPU.
See the flow diagram which describes the menu structure. Press the ENTER key on the HHT to
cause the initial menu (menu-A) to display on the terminal as shown below (the version and date
may be different). Unless otherwise specified, the F3 or ESC key (shifted Z) may be used to exit from
a menu to return to the previous level or abort an edit operation.

(5) Menu-A is the TOP level menu that is displayed when the ENTER key is pressed on the HHT. The
Version (04), Revision (-), and date of release (08NOV95) are displayed on Line#2. F1, F2 and F3
are the three options from this menu. F3 will return the system to normal operation and display the
message "TERMINAL INACTIVE" to indicate that the system is not reading any keystrokes from the
terminal but the ENTER key which will reopen MENU-A.
(6) Pressing F1 will enter the MENU-B1, while pressing F2 will enter MENU-B2.
