Installing the Batteries
■
Always handle the batteries with care and use them only as directed. Improper use may result
in battery explosion, cracking or leakage, which could result in fire, injury and/or pollution of the
surrounding environment.
• Be sure to use only the batteries specified. Do not use batteries of different types at the same
time. Do not mix a new battery with used one.
• Make sure the plus and minus terminals are correctly aligned when loading a battery.
• Keep a battery away from children and pets.
• Do not recharge, short circuit, solder or disassemble a battery.
• Do not place a battery in a fire or water. Keep batteries in a dark, cool and dry place.
• If you observe battery leakage, wipe out the leakage and then replace a battery. If the leakage
adheres to your body or clothes, rinse well with water immediately.
• Obey the local laws on disposing the battery.
Insert the batteries into the remote control before using it. If the remote control starts to malfunction,
replace the batteries. If not using the remote control for long period, remove the batteries from the
