[About the Economy Mode]
When the FC-50 is being operated with batteries, the Economy
mode can be used to effectively extend battery life by about
twice as long as usual.
The Bank Display may become somewhat dimmer and it may
flicker a little, but this is not an indication of a problem.
x The default MIDI channel of the FC-50 is channel 1, Refer to
"Changing MIDI Channels" ( page 11) if you want to change
the default setting.
* When using the FC-50 with the BOSS SE-50, set the MIDI
channel of the SE-50 to channel 1 (as shown in the owner's
manual of the SE-50) .
