1. Store them sealed in a specific place to prevent exposure to high temperature or direct sunlight.

4. Avoid using them as much as possible. When required, remove only required amount from the
container to make full use.

2. When installing plastic parts, insert the specific screws vertically to the parts. (Be careful not to

wiring, please perform your work as illustrated below.
If grounding is impossible, connect a cable to a steel desk or shelf.
