Optimus MD-1600 ユーザーズマニュアル

8

You can power your MD-1600 from
standard AC power using a 12-volt AC
adapter (not supplied) and a Size M
Adaptaplug.

You must use an AC
adapter that supplies 12
volts and delivers at least

1.5 amps. Its center tip must be set
to negative, and its plug must cor-
rectly fit the MD-1600’s 

 jack.

Using an adapter that does not meet
these specifications could damage
the MD-1600 or the adapter.

• Always press 

 to turn off the

keyboard before you connect or dis-
connect the adapter.

• Always plug the AC adapter into the

MD-1600 before you plug it into the
AC outlet. Always unplug the AC
adapter from the AC outlet before
you unplug it from the MD-1600.

Follow these steps to power your MD-
1600 from AC power.

1. Insert the adapter’s barrel plug into

the 

 jack on the back of the

MD-1600.

2. Plug the adapter into a standard AC

outlet.

To listen to your MD-1600 without dis-
turbing others, you can connect a pair of

-inch (6.35-mm) plug stereo head-

phones (not supplied). Your local Ra-
dioShack store sells a wide selection of
headphones.

the headphones’

into the 

  jack  on  the

back of the keyboard.

Note: Connecting headphones discon-
nects the MD-1600’s built-in speakers.

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.
