The M2 is equipped with an internal digital pressure sensor for the LPR. You are able to
view your LPR’s pressure at any time on the OLED screen. The Pressure readings can be
viewed by entering into the Data settings menu and scrolling to the Pressure Gauge screen,
or while in the playing screen you can press the joystick left and the Systems Check screen
will appear for 10 seconds, and display your gun’s PSI reading along with other information
about the M2’s operating system.
The M2 software tracks how many shots the marker has fired, and will
alert you when service is due. A red service icon will flash over the playing
screen. See service system on page 8 for more info.
