Introducing the R-4 Pro
Battery compartment
Install batteries here if you want to operate the R-4 Pro on battery power.
The orientation in which you must insert the batteries is shown on the side of the battery compartment.
Be sure to observe the correct polarity when installing the batteries.
If you’re using the AC adapter, there’s no need to install batteries.
When the R-4 Pro has sufficiently charged batteries, the power source automatically switches between
battery and external power when the external power connector is connected or disconnected.
For details, refer to “Installing batteries and turning on the power” (p. 26).
