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.
