Using AC Power
You can power your MD-1150 from
standard AC power using a 9-volt AC
adapter (not supplied) and a Size M
Adaptaplug
®
.
Cautions:
You must use an AC
adapter that supplies 9
volts and delivers at least
800 milliamps. Its center tip must be
set to negative, and its plug must
correctly fit the MD-1150’s
DC 9V
jack. Using an adapter that does not
meet these specifications could
damage the MD-1150 or the
adapter.
• Always press
POWER
to turn off the
keyboard before you connect or dis-
connect the adapter.
• Always plug the AC adapter into the
MD-1150 before you plug it into the
AC outlet. Always unplug the AC
adapter from the AC outlet before
you unplug it from the MD-1150.
Follow these steps to power your MD-
1150 from AC power.
1. Insert the adapter’s barrel plug into
the
DC 9V
jack on the back of the
MD-1150.
2. Plug the adapter into a standard AC
outlet.
CONNECTING
HEADPHONES
To listen to your MD-1150 without dis-
turbing others, you can connect a pair of
1
/
4
-inch (6.35-mm) plug stereo head-
phones (not supplied). Your local Ra-
dioShack store sells a wide selection of
headphones.
To connect a pair of headphones, insert
the headphones’ plug into the
PHONES/
OUTPUT
jack on the back of the key-
board.
Note: Connecting headphones discon-
nects the MD-1150’s built-in speakers.
Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the volume to
a comfortable level.
• Do not listen at extremely high vol-
ume levels. Extended high-volume
listening can lead to permanent
hearing loss.
