Aim/Autofocus
This function causes the laser pointer to turn on. The laser pointer can be used to posi-
tion the imager on the code, but note that the center of the cross is 16 mm (14 LEDs
model) or 30 mm (36 LEDs model) under the optical axis. The Aim LED blinks to indicate
this state. After a short delay, this function also performs the Autofocus procedure for
Liquid Lens models.
You can exit the Aim/Autofocus function at any time by pressing the X-PRESS push but-
ton once. After a short delay the Autofocus procedure is canceled and the laser pointer
turns off.
Setup
Once entered, the imager automatically performs Image Acquisition parameter calibra-
tion for the specific code presented to it.
The Setup LED will blink until the procedure is completed.
The Setup procedure ends when the Image Acquisition parameters are successfully saved
in the reader memory, the Setup LED will stop blinking and Matrix 320 emits 3 high
pitched beeps.
If the calibration cannot be reached after a timeout of about 5 (five) seconds Matrix 320
will exit without saving the parameters to memory, the Setup LED will not remain on
continuously but it will stop blinking. In this case Matrix 320 emits a long low pitched
beep.
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 suc-
cessfully saved in the reader memory, the Green Spot is activated, the Learn LED will
remain on continuously and Matrix 320 emits 3 high pitched beeps.
If the calibration cannot be reached after a timeout of about 3 (three) minutes, Matrix
320 will exit without saving the parameters to memory, the Learn LED will not remain
on continuously but it will stop blinking. In this case Matrix 320 emits a long low pitched
beep.
