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 60 kHz.
i) For the longest time without pulse is only 100 us. If there is no pulse output, please stop
marking 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.
