To ensure technician and user safety and to prevent the laser beam from
inadvertently switching on during servicing, there are four safety switches inside
the front cover (these are the 4th front left and 4th front right door safety switches).
When one of the front covers is open, the 5 V line connecting to the LD drivers
(LDD) is disconnected.
