Precautions

1. Precautions

1-1 Static electricity sense device

Some semi-conductor parts may be easily damaged due to static electricity.

These elements are generally called as static electricity sense device (ESD). Typically examples of EST

include IC, some transistor and chip element for semi-conductor with electrical field effect.

The following methods should be used to reduce damage of elements occurred due to static electricity:

1. Contact and emit all the grounding objects with static electricity from your body before handling with

elements for semi-conductor or devices with elements for semi-conductor. You should purchase and use

static electricity arm rings or commercially available. You should remove it due to potential shock before

supplying power to the device under test.

2. You should place appliance on the conductive surface like aluminum film to prevent that static electricity

is accumulated or the device is disclosed outside after removing electrical appliance with the ESD device.

3. You should use only soldering iron that is ground when soldering the ESD device.

4. Minimize physical operation when handling with the ESD device for replacement without packing

(Otherwise, namely friction between cloth fibers or lifting of the foot from the carpet floor may cause sta-

tic electricity enough to damage the ESD device).

1-2 Cautions for Safety

1. To remove dust from cabinet, use a dry cloth without using liquid and aerosol cleaner.

2. You should not use attachments not recommended by the company. Otherwise, it may cause critical

damage.

3. You should not use this product near water such as bathtub, swimming pool or lake etc.

4. Power supply: A type of battery as displayed on the label should be only used.

5. You should not put any object or liquid into product. Otherwise, it may cause failure or mal-operation.

6. If replacement material is required, service engineer should use materials with the same standard. The

use of non-standardized materials may cause failure of product.
