Elimination methods for abnormal phenomena
NO1: The power indicator light is not on.
Reason：1) Ac 220V is not connected properly.
2) The indicator light is broken.Replace the power cord.
NO2: The protection indicator light is on and there is no rf output.
Reason：1) Internal overheating, protection unit action.
2) The outer protection contact is disconnected.
3) The Q element does not match the driver, or the connection between the two is unreliable, which causes too much reflection and leads to the action of the internal protection unit.Improve cooling conditions.Check the outer protection contacts.Standing wave ratio.Consult our company.
NO3: Operation indicator light is on, no rf output.
Reason：1) The output control signal is always effective.
2) RUN/ t-on/t-off select the wrong switch position.Check out the light control signal pulse.Put the switch in the right position.
NO4: Processing graphics and text disorder.
Reason：Error setting output effective level.Reset the photoactive level.
NO5: The laser power can be turned off slightly.
Reason：1) There is something wrong with the Q switch element.
2) Low output rf power.Check the Q switch.Adjust the output rf power.
NO6: Low peak power of laser pulse.
Reason：1) Low average laser power.
2) There is something wrong with the Q switch element.Adjust the light path.Check the Q switch element.
