Cover (MD)

Laser Emitting conditions:

1) When the Cover (MD) is removed, and the POWER SW is turned to the ON" position, the laser component will emit a
beam for several seconds to detect if a disc is present. During this time (5-10 see), the laser may radiate through the
lens of the laser pick-up unit. Do not attempt any servicing during this period!

If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laser
emrssrons.

2) The laser power level can be adjusted with the VR on the pickup PWB, however, this level has been set by the factory
prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this
manual. Adjustment of this control can increase the laser emission level from the device.
