7.1 Storage

Store product in room condition. Avoid exposing product to direct sunlight or contact with acid, alkali or other types of solution.

 

Do not pile or place heavy objects on top of product.

 

Handle product with care. Avoid dropping, bumping or colliding.

 

7.2 Handling and cleaning

Wear finger-cots and masks when handling product. Avoid direct contact with product surface in case of stains.

 

Do not pull FPC in case of damage when handling product.

 

Product can be cleaned with soft cloth. Soak cloth in a solution of neutral detergent or alcohol, wipe surface of the product with it.

 

7.3 Mounting

For structure: L+F+G/L+F+F+S

See the structure below for an example of mounting.

 

 

For structure : L+F+G. The glass should be finely supported to avoid separation.

Please leave a clearance of 0.15mm at min. between the front case and cover lens.

Don't pull or bend the FPC when mounting. Don't insert the FPC into connector at the edge of stiffener to avoid fracture or damage. Please avoid the mounting method as shown in the following illustration.

 

7.4 Operating

Avoid operating with hard and sharp objects in case of damage to product.
