Learn; Diagnostic Indication - Datalogic Matrix 120 Product Reference Manual

Learn

Once entered, the imager starts a procedure to automatically detect and
recognize a single code which is presented to it. Successive Learns will
substitute the current code.
The Learn LED will blink until the procedure is completed.
The Learn procedure ends when the Image Processing and Decoding parameters
are successfully saved in the reader memory, the Green Spot is activated, the
Learn LED will stop blinking and Matrix 120 emits 3 high pitched beeps.
If the autolearning cannot be reached after a timeout of about 3 (three) minutes,
Matrix 120 will exit without saving the parameters to memory, the Learn LED will
stop blinking and in this case Matrix 120 emits a long low pitched beep.
You can exit the Learn function at any time by pressing the X-PRESS push button
once. After a short delay the Learn procedure is canceled.
