PREPARATION
Note: To connect a MIDI device, see
“Making the MIDI Connections” on
Page 25. To connect a sustain pedal,
see “Using a Sustain Pedal” on
Page 24.
CONNECTING POWER
You can power your MD-1150 from ei-
ther:
internal batteries (see “Using Batter-
ies”)
standard AC power using an
optional AC adapter (see “Using AC
Power” on Page 8)
Notes:
Connecting an AC adapter automat-
ically disconnects internal batteries.
Always disconnect the adapter
when you finish using the MD-1150.
Using Batteries
Your MD-1150 can use six D batteries
(not supplied) for power. For the best
performance and longest life, we recom-
mend RadioShack alkaline batteries.
Cautions:
Use only fresh batteries of the
required size and recommended
type.
If you do not plan to use the MD-
1150 with batteries for a week or
more, or if you will be using only AC
power, remove the batteries.
Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
1. Press the tabs on the battery com-
partment cover, then pull up to
remove the cover.
2. Put the batteries in the compartment
as indicated by the polarity symbols
(+ and –) marked beside the com-
partment.
3. Replace the cover.
If the MD-1150 sounds weak or does not
work properly, replace all six batteries.
Warning: Dispose of old batteries
promptly and properly. Do not burn or
bury them.
Caution: Always remove old or weak
batteries; batteries can leak chemicals
that can destroy electronic parts.
