PREPARATION
Note: To connect a MIDI device, see
“Making the MIDI Connections” on
Page 41. To connect a sustain pedal,
see “Using a Sustain Pedal” on
Page 31.
CONNECTING POWER
You can power your MD-1600 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-1600.
• Disconnecting the keyboard’s power
clears the control settings, memory
contents, and user tones (see
“Using the Custom Tone Synthe-
sizer” on Page 24 and “Using the
Memory” on Page 32).
Using Batteries
Your MD-1600 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-
1600 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-1600 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.
