Warning W06: temperature of handpiece treatment head exceeds the upper limit
a) This failure means that “temperature of handpiece treatment head exceeds the upper limit”, and test should be implemented only under the ready state.
b) If handpiece refrigeration fails or temperature is increased under the ready state, resolve the failure by referring to Refrigeration Failure of Handpiece.c) If handpiece refrigeration works, the detection is very likely to be caused by the long-time high-energy laser emission. Continue the use after pressing ready key again.
d) If handpiece refrigeration works, long press “W06” for 5 times to enter the background; when the display temperature does not comply with the actuality after entering password “3”, it should be the failure of handpiece temperature sensor. Check whether the sensor wiring harness is loose; if no problem is discovered, replace the handpiece control board.
e) If it is obviously felt that the refrigeration speed is insufficient or there is a great difference between the two handpieces, the failure may be caused by the aging damage of TEC after reaching the service life. The failure may also be due to the installation problem of TEC. Apply the thermally conductive silicone grease to the two faces of TEC and closely cling it to the aluminum piece without any gap.
