Safety Precaution
Precautions for Optical Parts
Observe the following rules for all the optical parts. Otherwise, the image quality may be
degraded.
• Before removing the covers, be sure to turn OFF the high-voltage switch. If the
machine is powered ON with any of the covers removed, the photomultiplier will be
damaged.
• Never touch the surface of optical parts.
• Do not attempt to remove dust or soil with procedures other than those specified.
• Remove optical parts in a clean environment. When removing protective housings to
replace optical parts, use care to avoid saliva from spattering around. Accordingly, it is
desirable to wear a mask.
Other General Precautions
General precautions to be observed when performing servicing procedures are described
below. Note that precautions for individual procedures are described for their respective
procedures and thus be observed accordingly.
• To avoid hazards and prevent damage to components, do not remove or install any
part while the machine is powered. When performing checks and adjustments under
the powered condition, exercise care against electric shock.
• To avoid hazards, do not put your hand on or into any rotating part. Also use care not
to get your hand, foot, hairs, or clothes entangled in the machine.
• Use care not to touch the erasure lamp by hand, because it remains at high tempera-
ture immediately after power is turned OFF.
• Since some components, such as the photomultiplier, are not sufficiently discharged
after power is turned OFF, exercise due care to avoid electric shock. (Do not touch any
exposed parts, such as connectors and terminals, by bare hand inadvertently.)
• When servicing any LD assembly and printed circuit board, be sure to wear an anti-
static wristband to ensure proper grounding. If not, static electricity built on the human
body may cause damage to electronic parts on the board.
• Keep clean the product labels, safety standards labels, product serial number indica-
tions, and so forth attached on the machine, and do not peel them or put another label
over them.
• Upon completion of the servicing procedures, put the protective housings, retaining
screws, and cover grounding back exactly where they were, and secure them in place.
