Power indicator |
2 |
Laser drive level indicator: Steady green light: Drive level is normal. Blinking red light: Drive level alarm. You can view the alarm in the Alarm Status, the second level submenu. |
3 |
Laser working status indicator: Steady green light: The laser is operating normally. Steady red light: The laser is not turned on. Blinking red light: The device has a parameter alarm. You can view the alarm in the Alarm Status, the second level submenu. |
4 |
Device running indicator: This indicator will flash by 1Hz frequency after the device start running normally. |
5 |
Laser switch: ON: The laser is on. OFF: The laser is off. Keep the laser off before the device is powered on, and turn on the laser after the self-inspection is completed when power on. |
