Notes on batteries
• Change both batteries when the operation range of the
remote control decreases.
• Use AAA, R03, UM-4 batteries.
• Make sure that the polarities are correct. See the
illustration inside the battery compartment.
• Remove the batteries if the remote control is not to be
used for an extended period of time.
• Do not use old batteries together with new ones.
• Do not use different types of batteries (such as alkaline
and manganese batteries) together. Read the packaging
carefully as these different types of batteries may have
the same shape and color.
• If the batteries have leaked, dispose of them
immediately. Avoid touching the leaked material or
letting it come into contact with clothing, etc. Clean the
battery compartment thoroughly before installing new
batteries.
• Do not throw away batteries with general house waste;
dispose of them correctly in accordance with your local
regulations.
