Step 3 - Aim and Autofocus the Reader
(Liquid Lens Models only)
Matrix 300N provides a built-in laser pointer aiming system to aid reader
positioning. For Liquid Lens models, the autofocus feature is also incorporated
into this function. The aiming system is accessed through the X-PRESS Interface.
1. Power the reader on. During the reader startup (reset or restart phase), all
the LEDs blink for one second. On the reverse side of the reader near the
bracket, the “POWER ON” LED (blue) indicates the reader is correctly pow-
ered.
2. Place the Grade A Barcode Test Chart in front of the reader at the correct
reading distance for your application. See the Global FOV Diagrams for ref-
erence.
3. Enter the Aim/Autofocus function by pressing and holding the X-PRESS
push button until the Aim LED is on.
4. Release the button to enter the Aim function. The laser pointers turn on,
and the Autofocus procedure begins, see Figure 4 . The Aim LED will blink
until the procedure is completed.
Within 3 seconds (before the reader flashes), center one of the larger codes
on the aiming system pointers (the code must not move during this proce-
dure).
The Autofocus procedure ends when the Reading Distance and PPI values
are successfully saved in the reader memory, the Aim LED will stop blinking
and Matrix 300N emits 3 high pitched beeps.
If the Autofocus cannot be reached after a timeout of about 3 (three) min-
utes, Matrix 300N will exit without saving the parameters to memory, the
Aim LED will stop blinking and in this case Matrix 300N emits a long low
pitched beep.

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 canceled and the laser
pointers turn off.
