描述

## Usage Instructions
1. Avoid strong collision, dropping and scratches from sharp objects to prevent shell cracking and internal structure offset.
2. Keep away from magnets, iron products and electromagnetic equipment, which will affect pointing accuracy.
3. Do not place in high temperature, humid or corrosive environment for a long time to avoid failure and discoloration.
4. The manufacturer shall not be liable for damage caused by improper use or man-made damage.

## Precautions
1. Wipe surface dust with soft dry cloth, do not soak in water arbitrarily.
