Using AC Power
You can power your MD-1200 from
standard AC power using a 9-volt AC
adapter (not supplied) and a Size M
Adaptaplug.
Cautions:
You must use a Class 2
power source that supplies
9 volts DC and delivers at
least 800 mA. Its center tip must be
set to negative and its plug must fit
the MD-1200's
DC 9V
jack. Using an
adapter that does not meet these
specifications could damage the
MD-1200 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-1200 before you plug it into the
AC outlet. Always unplug the AC
adapter from the AC outlet before
you unplug it from the MD-1200.
Follow these steps to power your MD-
1200 from AC power.
1. Insert the adapter’s barrel plug into
the
DC 9V
jack on the back of the
MD-1200.
2. Plug the adapter into a standard AC
outlet.
CONNECTING
HEADPHONES
To listen to your MD-1200 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’
1
/
4
-inch (6.35-mm) plug
into the
PHONES/OUTPUT
jack on the
back of the keyboard.
Note:
Connecting headphones discon-
nects the MD-1200’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.
