(Connectors)

Do not connect or disconnect while power is on.

Connecting or disconnecting signal wires or the main power cord

when 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 an

erroneous 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 terminals

directly.

If the worker is grounded, there is nothing to worry about static

electricity, but the rust on the connector terminal surface caused

by the touch may result in bad contact.

(Caution)

Before disconnecting FFC

cable, make it "SHORT" as

shown left.

After connecting FFC

cable,make it "OPEN" as

shownleft.

(Power source)

The power source need be good in quality (free from

instantaneous interruptions 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 dew

condensation is possible.

The entry and deposition of dirt or dust into or on the pickup lens

or moving section will cause malfunction or degradation.

Also, dew condensation causes rust; the rust penetrate into the

precision part of a pickup, causing malfunction, or degrading the

optical quality of the internal lens and reflector, which also leads

to malfunction.

1. Cautionary instructions in handling the assy

(Safety instructions)

Optical pickup

The laser beam used in the pickup is classified as "class 2".

Exposing your eyes or skin to the beam is harmful. Take care

not 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

used in the production lines and inspection departments that

handle loaders. The workers shall also be grounded.

(Cautionary instructions in handling)

Do not touch the object lens when handling a loader, or the lens

will be stained, resulting in inadequate playability.

There is no power supply protection circuit provided for this

product or adjustment/inspection device. Short-circuiting may lead

to fire or damage.

Take care so as to protect from exposure to water, the entry of

metallic pieces or dew condensation.

In particular, a strong magnet adjacent to the pickup will not only

get 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 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 it

should occur, refer to clause 2.

This product is so designed as to endure an initial shock

equivalent to a drop from a height of approx. 90 cm under the

packed condition.

After the initial shock, the resistivity will still remain at a level of

50 to 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

moving section will cause malfunction or degradation.

Symbol Pin Name Function

To provide memory addresses. During Sector-Erase A

-A

address

lines will select the sector. During Block-Erase A

-A

address lines will

select the block.

To output data during Read Cycles and receive input data during Write

Cycles.

Data is internally latched during a Write Cycle.

The outputs are in tri-state when OE# or CE# is high.

To activate the device when CE# is low.

To gate the data output buffers.

To control the Write operations.

To provide power supply voltage:

Unconnected pins 3.0-3.6V for SST39LF200A/400A/800A
