Test Mode (Function 1)
Once entered, the Bar Graph on the five LEDs is activated and if the imager starts reading
codes the Bar-Graph shows the Good Read Rate. In case of a NO READ condition, only the
Status LED is on and blinks.
The Bar Graph has the following meaning:
To exit the Test Mode, press the X-PRESS™ push button once.
NOTE: By default, the Test exits automatically after three minutes.
Aim/Autofocus (Function 2)
This function causes the laser pointers to turn on. Since the laser pointers are centered on
the FOV they can be used to position the imager on the code. 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 button
once. After a short delay the autofocus procedure is cancelled and the laser pointers turn off.
Setup (Function 3)
Once entered, the imager automatically performs Image Acquisition parameter calibration 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 300™ emits 3 high pitched
beeps.
If the calibration cannot be reached after a timeout of about 5 (five) seconds Matrix 300™ will
exit without saving the parameters to memory, the Setup LED will stop blinking and in this case
Matrix 300™ emits a long low pitched beep.
