Operating System
The AT550 incorporates a user-friendly icon/menu-based operating system. This
system will speed up your training time, since you do not have to memorize many
functions before using the instrument.
Instrument functions are initiated by pressing the gray buttons located below the
icons displayed on the screen (picture below).
Descriptions of icons are provided on pp. 7-8.
