Introduction
Installing Batteries
If you install ten AA rechargeable nickel-metal hydride batteries,
you’ll be able to perform without connecting the AC adaptor. By
using the FR-4x with its built-in speaker on battery power, you can
play it like an acoustic accordion without connecting a cable.
About the batteries that can be used

When using rechargeable nickel-metal hydride batteries
(2000 mAh batteries), you can use the instrument
for approximately five hours if the speaker is on, or
