■ Precautions

Chemicals

Handle chemicals of high volatility with care, use of which will affect to your health and environment.

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

2. Avoid dividing them into small containers and prevent vaporization.

3. Keep containers sealed when not in use.

4. Avoid using them as much as possible. When required, remove only required amount from the

container to make full use.

Plastic parts

1. When cleaning plastic parts, use cleaning paper or cloth. Never use thinner, ketone, ether.

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

tighten too much.

PCBs

Since PCBs use MOS IC, you must reduce static electricity. When repairing a PCB itself, or when

wiring, please perform your work as illustrated below.

If grounding is impossible, connect a cable to a steel desk or shelf.

Unleaded solder

This model uses lead-free solder.

The cautions on use:

1. A soldering iron tip temperature of 280 - 350℃ is sufficient, but when it cannot melt solder, use a

higher temperature for a short period of time.

2. Be sure to control soldering iron tips used for lead-free solder and those for leaded solder so they are

managed separately.

This is because mixing lead-free solder and leaded solder will cause detachment phenomenon.
