Warning E18: output pulse width is too large
a) This failure means the “too large of laser emission pulse width”. Use it again after restarting the instrument. If this failure occurs again, find out the problem. If no problem is discovered, it will be caused by interference. At this time, continue to use it by ignoring this problem.
b) Plug off the main control board J12 and restart the instrument for retest. If this failure is eliminated, try replacing the DB9 wiring harness and laser power supply.
c) If this failure is not eliminated, try replacing the main control board of main console.

Warning E16 电流检测——出光电流检测过大/过小
a) 此故障代表“电流检测——出光电流检测过大/过小”。请重启仪器后再次使用，如果此故障仍出现，则查找问题，否则为干扰导致，可忽略继续使用。 b) 首先断电后，目视手柄治疗窗口，观察半导体激光器是否有烧毁损伤痕迹（单巴有明显黑点或黑条），如果有，则为半导体激光器损坏，需要更换半导体激光器。 c) 可以用相纸测试，把能量密度调至5-10J/cm²，试验是否出光。 d) 出光情况下，请测试200ms脉宽，1Hz，出光1次，10J/cm²和30 ...
Warning W08
a) 此故障代表“水箱温度超出上下限”，极有可能是手柄长时间以高能量出光导致的。此提示会在水箱温度恢复正常后自动消失。 b) 如果该故障提示很容易出现（持续工作1h以内就会出现），则考虑为仪器故障。 c) 首先查看水质检测板显示水温，如果未出现温度跳变现象，则排除温度传感器接触不良问题，否则需检查温度传感器或更换水质检测板。 ...
