• Change all of the batteries if the operation range of the remote control decreases.
• Use AA, R6, UM-3 batteries for the remote control.
• Make sure that the polarities are correct. See the illustration inside the battery compartment of each remote control.
• Remove the batteries if the remote control is not 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.

• We strongly recommend using alkaline batteries.
