NOTES:
● Follow these precautions for battery use.
1. Never use the new and used batteries together.
2. Never use different types of batteries (for example manganese battery and alkaline battery) together.
3. When the wireless controller is not used for a long time (more than 2 or 3 months), remove the batteries.
● When the batteries are replaced, wait at least 5 seconds before installing new batteries.
