Select Key
The operator instructions written for this manual
were based on stepping through the software menu
using the keys below the display. Once you are com-
fortable operating the AT-500, you might find it faster
to use the SELECT key to access some functions. These
include: Units, Scale, Start and Stop Frequencies in
swept frequency mode and Units, Scale and Frequency

Press the SELECT key until the cursor is blinking at
the desired function. The first function enabled depends
on the last function selected through the menu.
