Battery Precautions

Warning
Incorrect battery usage may cause batteries to rupture and leak battery fluid, which could result in fire, injury, or corrosion of the remote control.
If liquid from a battery gets in your eyes, do not rub your eyes. Wash them well with clean water and contact a doctor immediately. If liquid enters your mouth, rinse
immediately with plenty of water and consult a doctor. If liquid from the battery comes in contact with your skin or clothes, wash with water to prevent possible skin
damage.
Keep batteries out of the reach of children. Batteries are a choking hazard and are very dangerous if swallowed.
Prepare two replacement manganese or alkaline AA batteries. Do not use any other kinds of batteries.
Insert batteries so that the polarities (+ and -) are correct. Not doing so may cause leakage, overheating, or explosion.
Do not use a new battery and an old battery, or different types of batteries at the same time. Doing so may cause leakage, overheating, or explosion.
Remove the batteries if you will not be using the remote control for a long period of time. When a battery runs down, take it out of the remote control immediately. If a
discharged battery is left inside for a long time, gas emitted from the battery may cause leakage, overheating, explosion, or damage to the remote control.
Do not heat batteries or put them into fire or water.
When you throw away the batteries, follow your area’s regulations regarding disposal or recycling.
