Operating Elements
Settings
Each parameter is set by means of a code. This code comprises a combination of keys starting with
the
ALT
key followed by two or three numbers. The setting is confirmed with the
STOP
key. As
soon as the
ALT
key is pressed, the keyboard is dedicated to the programming function.
Note:
When the ALT key is pressed `ALT` appears on the LCD (see previous page)
Note:
The Alternative (ALT) function is only active for 4 seconds. If a programming key is
not pressed within 4 seconds, the unit reverts to standard mode. The ALT key must
again be pressed to activate the programming mode
The setting is remembered and the keyboard released for other functions when the
STOP
key is
pressed. Once a setting has been confirmed, it is stored in the memory even when the unit is
switched off.
Example
If you want to reset your AT-2
plus
to the basic default settings, the key sequence given on page
14 is ALT; 0; 6; 6. STOP.
On the following pages the programmable parameters and the programming sequences are described
