It covers usable and unusable containers, automatic keys for warming, defrosting, milk, sake and boiled vegetables, manual high/low power, a heating time chart, cleaning, specifications, warranty and after-sales service, and troubleshooting. This manual is written in Japanese.
No. The manual says metal reflects microwaves and may produce sparks.
