■ Installing batteries

the remote control narrows. Before inserting new
batteries, wipe the battery compartment clean.
AA, R6, UM-3 batteries
CAUTION
• Be careful not to drop the remote control.
• If the batteries run out, immediately remove them from the remote control to prevent an explosion or acid leak.
• If you find leaking batteries, discard the batteries immediately, taking care not to touch the leaked material. If the leaked material
comes into contact with your skin or gets into your eyes or mouth, rinse it away immediately and consult a doctor. Clean the battery
compartment thoroughly before installing new batteries.
• Do not use old batteries together with new ones. This may shorten the life of the new batteries or cause old batteries to leak.
• Do not use different types of batteries (such as alkaline and manganese batteries) together. Batteries that look the same may have a
different specification.
• Dispose of batteries according to your regional regulations.
• Keep the batteries in a location out of reach of children.
Batteries can be dangerous if a child were to put in his or her mouth.
• If you plan not to use this unit for a long period of time, remove the batteries from this unit. Otherwise, the batteries will wear out,
possibly resulting in a leakage of battery liquid that may damage this unit.
