Cautionary instructions in handling the assy(Safety instructions)Optical pickupThe laser beam used in the pickup is classified as class 2. Exposingyour eyes or skin to the beam is harmful. Take care not

20、 to do so.(Caution against static electricity and leakage voltage)Ground securely the work tables, tools, fixtures, soldering irons(including those made of ceramic) and measuring instruments usedin the production lines and inspection departments that handleloaders. The workers shall also be grounded

21、.(Cautionary instructions in handling)Do not touch the object lens when handling a loader, or the lenswill be stained, resulting in inadequate playability.There is no power supply protection circuit provided for this productor adjustment/inspection device. Short-circuiting may lead to fire ordamage.

22、Take care so as to protect from exposure to water, the entry ofmetallic pieces or dew condensation.In particular, a strong magnet adjacent to the pickup will not onlyget inoperative but can damage the pickup if a small metallic piece,such as a screw or swarm, enters.The loader edge can cause injury

23、if inadvertently handled.Do not touch a rotating disk, or injury may result.This product is a precision device. Handle carefully.A shock or dropping will cause misalignment or destruction. If itshould occur, refer to clause 2.This product is so designed as to endure an initial shock equivalentto a d

24、rop from a height of approx. 90 cm under the packed condition.After the initial shock, the resistivity will still remain at a level of 50to 60 G, but the mechanical robustnessThe entry and deposition of dirt into or on the pickup lens or movingsection will cause malfunction or degradation.(Connector

25、s)Do not connect or disconnect while power is on.Connecting or disconnecting signal wires or the main power cordwhen the power is on may destruct the unit or fixture.When connecting, push all the way in securely.An insufficient insertion may cause a bad contact, leading to anerroneous operation.Do n

26、ot connect or disconnect roughly by an excessively strong force,or a broken wire or bad contact may result.Semiconductors are connected. Do not touch connector terminalsdirectly.If the worker is grounded, there is nothing to worry about staticelectricity, but the rust on the connector terminal surfa

27、ce causedby the touch may result in bad contact.(Power source)The power source need be good in quality (free from instantaneousinterruptions or noises).A low quality power source may well cause malfunction.(Storage)Do not place or store in a dusty place or a place where dewcondensation is possible.T
