Q
The power does not turn on.

an AC outlet and to the rear panel power connector, and that the
adaptor itself and AC power cord are connected correctly (p. 17).

batteries are installed, the AC adaptor will be used preferentially.
Even if batteries are installed, the power will not turn on unless the
AC adaptor is connected to an AC outlet.
•If you’re using batteries, disconnect the AC adaptor from the JUNO-
Di. If batteries are installed, connecting or disconnecting the power
cord from the outlet or connecting or disconnecting the DC plug of
the AC adaptor while the JUNO-Di is turned on will cause the power
to turn off.
