SUSPECTED FAILURES
Whenever it is likely that safe operation is impaired, the apparatus must be
made inoperative and secured against unintended operation. The appropriate
service authority must then be informed. Do not operate with suspected
failures. Servicing is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, the apparatus has been exposed to rain
or moisture, does not operate normally, or has been dropped.
PREVENTIVE MAINTENANCE: CLEANING
Qualified Service Personnel Only: The apparatus should be cleaned often
enough to prevent dust or dirt from accumulating. Dust accumulating in the
apparatus acts as an insulating blanket, preventing proper cooling, and
possibly causing overheating and component breakdown. Under high humidity
conditions, accumulated dust can also provide an electrical conduction path.
Remove accumulated dust with a soft cloth or small paint brush. Remove
hardened dirt with a soft cloth, dampened in a mild detergent and water
solution. Do not use polish or abrasive cleaners or any other chemical cleaning
agents.
PREVENTIVE MAINTENANCE: VISUAL INSPECTION
Qualified Service Personnel Only: Visually inspect the apparatus for signs of
damage, scorched components, and loose or disconnected pin connectors. If
you discover heat damaged parts, try to determine the cause of the
overheating before replacing the damaged parts; otherwise, the damage may
repeat.
ATTENTION:
Observe precautions for handling electrostatic-sensitive devices. See “Electro
Static Discharge (ESD) Precautions” below for details.
