Points for CDM 12 (NSM) Player.
This procedure is recommended to be carried out in a workshop.
The mechanism of the CDM PRO module consists of delicate optical, mechanical
and electrical components; therefore, proper handling measures have to
avoid damage to the laser by Electro Static Discharges(ESD),
service technicians and operators should be grounded during handling.
Excessive mechanical forces on any part should be avoided.
Storage in dusty, high temperature and high humidity environments should
Never touch the lens with your fingers, and avoid spoiling the lens with
grease from the mechanical parts.
Work in a clean environment.
The Optical Pick Up unit has been carefully adjusted during manufacturing.
Avoid touching this part. Do not disassemble. Do not readjust.
Always use proper tools to handle the unit.
Fast heating up (e.g. by bringing the mechanism from a cold place into
a warm and humid room) can result in moisture condensing on the lens,
thus influencing the playability for a certain time.
Before checking the performances, the mechanism should stabilize to climatic
conditions for at least 4 hours.
WARNING: INVISIBLE LASER RADIATION. AVOID DIRECT EXPOSURE TO THE LASER
BEAM. THE LASER BEAM CAN DAMAGE THE HUMAN EYE.
