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 battery fluid gets in your eyes, do not rub your eyes. Wash them well with clean water and contact a doctor immediately.
If battery fluid enters your mouth, rinse immediately with plenty of water and contact a doctor immediately.
If battery fluid comes in contact with your skin or clothes, wash with water to prevent possible skin damage.
Keep batteries out of the reach of children; they are choking hazards and are very dangerous if swallowed.
Prepare two replacement manganese or alkaline AA batteries. Do not install batteries of different types, or mix new and old batteries.
Insert batteries so that the polarities (+ and -) are correct. Not doing so may cause leakage, overheating, or explosion.
Be sure to replace both batteries with new ones of the same type. Not 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
used-up 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 expose batteries to heat, flame, or water.
Dispose of used batteries according to local regulations.
