After the program loads, a prompt appears giving you a choice of either the

when using the program for the first time.
When entering the main program the first menu is a 3-D window with a highlight
bar on the first menu selection. Make your choice by either pressing a letter
corresponding to the capital letter in the menu choice, or use the cursor up /
down keys to move the highlight bar to the desired selection and hit the RET-
URN key. The second menu will partly overlay the first.
The same selection process applies to the second menu, only some choices have
numbers instead of capital letters. After the menu selection is made, a sub-
menu will appear at the bottem of the window on some programs. select choice
using the cursor left / right keys or enter the number or capital letter
corresponding to your choice. (If you want to back up to make a different
selection, press the F-2 key) When selection is made a third 3-D window app-
ears also partly over-laying the second menu. If you would like to go back to
the second menu at this time, just hit RETURN. If not, then enter the desired
frequency (as prompted) and hit ENTER. You will now be in the DISPLAY screen.
The Display screen will show a "blueprint" of the desired antenna. for more
information on this antenna, hit the T key (text) and a window will overlay
the screen giving additional information on the selected antenna. Hitting the
SPACEBAR will remove this window. WARNING: should you choose to use the F-1
option (program info.) at this time you will NOT return back to the display
screen, but will return to the main menu instead.
To print a copy of the display screen on your printer, use the SHIFT-PRT SC
keys. NOTE: If your printer does not contain the IBM EXTENDED CHARACTER
SET, the print-out will not be the same as seen on your monitor.
MONOCHROME DISPLAY: If you are using MDA or HGA with your system, then be sure
that the contrast and the brightness controls om the monitor are adjusted
properly or else you may not see all of the information displayed in the 3-D
windows.
