A button/coin-shaped battery is used in the remote controller of the appliance. If you accidentally swallow the battery, consult a doctor immediately for emergency treatment. If you fail to receive first aid within 2 hours after you swallow the battery, you may experience damage to your internal organs or death in severe cases.
Do not swallow the battery.
If the battery tray is not secured firmly, stop using the remote immediately and keep it away from children.
