BASIC Operation
Using the Front Panel Buttons
All operations of the AT-100ProII are controlled via the front panel buttons. Although there
are a total of seven buttons on the front panel, there are more than seven functions that can be
carried out on the AT-100ProII. In order to accommodate the many functions of the AT-
100ProII, the operation performed by pressing a particular button is determined by the manner in
which the button is pressed, and no operation begins until the button is actually released.
The various types of button presses are described here:
Momentary or short press: The button is pressed and released immediately.
Medium Press: The button is held for one-half to 2.5 seconds, and then released.
Long Press: The button is held for more than 2.5 seconds, and then is released.
FUNC -> Button: The FUNC button is pressed first, and then the button is pressed
momentarily and released. e.g.: FUNC -> Ant means “Press the Func button and release, then
press the Ant button and release.”
User Configuration Options
The AT-100ProII offers several user-settable options that allow the behavior of the tuner to
adapt to many different operating circumstances. Most of these options are accessed by placing
the tuner in Function mode, which is done by pressing and releasing the Func button, and then
pressing the desired button to activate the particular configuration option while in function mode.
To confirm entry into Function mode, the AT-100ProII will flash an “up arrow” on the LED
display after the Func button is pressed.
