LaserMaster power-unit alarm: reboot, then USB-serial or LAN remote Source-Date (SAST): 2024-03-11 11:52 Dest: public Review-after: 2027-02-28 Status: current Facts If the LaserMaster laser power unit alarm is on, first reboot the unit and see if the alarm clears. If it does not: you need a computer with internet. Each LaserMaster has a USB-to-serial cable inside, or you can use a network cable. Open the side cover and connect at the table on the back of the laser power unit. Run the remote-assistance app from am.co.za/remote so support can diagnose the alarm. Do not clear a live error before support/factory has seen the cause.
