Connecting The Ac Adaptor - Roland FR-4X Owner's Manual

Connecting the AC Adaptor

* To prevent malfunction and equipment failure, always turn
down the volume, and turn off all the units before making any
connections.
* We recommend that you keep batteries installed in the unit
even though you'll be powering it with the AC adaptor. That
way, you'll be able to continue a performance even if the cord of
the AC adaptor gets accidentally disconnected from the unit.
1.
Turn the [VOLUME] knob all the way to the left to
minimize the volume.
2.
Connect the included power cord to the AC adaptor.
* Place the AC adaptor so the side with the indicator (see
illustration) faces upwards and the side with textual information
faces downwards. The indicator will light when you plug the AC
adaptor into an AC outlet.
