Install LaserOS on your Android device, Mac, or Windows PC as described in the Installing LaserOS section.
Connect the correct cable. For Mac and Windows PCs, a USB to Micro USB cable is required. For most Android devices, a USB-C to Micro USB cable is required.
Make sure the safety jumper is installed. Turn the key to the on position. Position yourself behind the laser and lower the beam blocker to the desired position (either fully open or partially blocking the beam for safety reasons).
Turn the power switch on. If LaserOS does not auto-detect your laser and start automatically, start the app.
