Installing batteries and turning the power on
Caution when using the R-4 on battery power
• If you operate on battery power for an extended time, the batteries will become hot. Be careful not to
burn yourself.
• We recommend that you use alkaline batteries, which have a longer life.
• Don’t mix new batteries with used batteries, and don’t mix batteries of differing types.
• If you won’t be using the R-4 for an extended time, we recommend that you remove the batteries to
prevent leakage or other accidents.
• When using a USB cable to connect the R-4 to your computer, you must use the AC adaptor to prevent
the loss of power while the connection is active.
