MATRIX 210N™ REFERENCE MANUAL
STEP 3 – X-PRESS CONFIGURATION FOR SOFTWARE ADJUSTABLE
FOCUS MODELS
NOTE: For Fixed Focus models go to Step 4.
Matrix 210N liquid lens models provide a built-in laser pointer aiming system to aid reader
positioning. For these 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 powered.
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 in chapter 6 for reference.
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 6. 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 procedure).
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 210N
emits 3 high pitched beeps.
If the Autofocus cannot be reached after a timeout of about 3 (three) minutes Matrix 210N
will exit without saving the parameters to memory, the Aim LED will stop blinking and in this
case Matrix 210N emits a long low pitched beep.

NOTE: 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.
