Automatic Power Control (APC)
The LD driver on the LD drive board automatically controls power for the laser diodes. The laser diode
power is adjusted at the factory.
LD Safety Mechanisms
Laser Safety Switch: There are safety switches on the front and rear covers. These switches stop the
laser while the cover is open. If the user opens one of these covers, the +5VLD power to the laser
diodes is stopped.
