Exposingyour eyes or skin to the beam is harmful. Take care not to do so.(Caution agai

The workers shall also be grounded.(Cautionary instructio

18、ns in handling)Do not touch the object lens when handling a loader, or the lens willbe 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.Take care so as to prot

19、ect 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 if inadvertently handle

20、d.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 drop from a height of ap

21、prox. 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 robustness will weaken.Do not place in a dusty location.The entry and deposition of dirt into or on the pickup lens or movingsection will cause malfunction or

22、 degradation.(Connectors)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 ane

23、rroneous operation.Do not 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 c

24、onnector terminal surface caused bythe 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 dewcon
