f) The device has three cooling fans at the rear panel to dissipate heat. In order to
guarantee enough airflow to help giving heat off, there must be a space of at least
10cm’s width for airflow in front and rear side of the device. As the cooling fans are
working at blow condition, if laser is mounted in a cabinet with fans, the direction
should be same as laser’s fans.
g) Do not look into the output head of the device directly. Please do wear appropriate
laser safety eyewear during the time when operating the device.
h) Make sure the pulse repetition rate higher than 30 KHz.
i) For the longest time without pulse is only 100 us. If there is no pulse output, please
stopmarking at once, to avoid further damage of the device.
j) Power source sudden interruption will do great harm to the laser device. Please make
sure the power supply works continuously.
