Battery compartment

If you want to operate the R-1 on batteries, install the batteries here. If you are operating

You must switch off the R-1's power before changing from AC adaptor operation to
battery operation, or from battery operation to AC adaptor operation.
Please read "Installing the batteries and turning on the power" (p. 20) before you use
the R-1.
