ˆ Features

Your RadioShack MIDI Keyboard is a state- of-the-artkeyboard with many exciting features. You can set the keyboard to sound like 50 different musical instruments. To accompany your music, the keyboard has 30 rhythms, as well as auto accompaniments and percussion sounds.

Your keyboard also includes a MIDI (Musical Instrument Digital Interface) OUT feature, which lets you connect it to other MIDIequipped musical instruments or devices — even your personal computer.

Music Information Display — shows you the notes and chords as you play them, along with the current tone, rhythm, and tempo.

Sustain Function — lets you extend the length of a played note, providing added flexibility as you make music.

Recording/Playback — lets you record your own tunes and play them back at any time.

Metronome — the keyboard sounds the beat, making it easy to keep time with the music.

Tempo Controls — let you speed up or slow down the tempo of any selected music pattern.

Note: This Owner’s Manual explains how to use this electronic keyboard. It does not teach music.

THE FCC WANTS YOU TO KNOW

This equipment complies with the limits for a Class B digital device as specified in Part 15 of FCC Rules. These limits provide reasonable protection against radio and TV interference in a residential area. However, your equipment might cause TV or radio interference even when it is operating properly. To eliminate interference, you can try one or more of the following corrective measures:

reorient or relocate the receiving antenna

increase the distance between the equipment and the radio or TV

use outlets on different electrical circuits for the keyboard and the radio or TV.

Consult your local RadioShack store if the problem still exists.

You must use shielded interface cables with this equipment.

Features

DC 9V

ˆ Preparation

To connect a MIDI device to your keyboard, see “Making the MIDI Connections” on Page 12.

CONNECTING POWER

You can power your keyboard in any of these ways:

internal batteries

standard AC power using an optional AC adapter

a vehicle’s cigarette-lightersocket using an optional DC adapter

Notes:

Connecting an AC or DC adapter automatically disconnects internal batteries.

Always disconnect the AC or DC adapter when you finish using the keyboard.

Using Batteries

Your keyboard can use six C batteries (not supplied) for power. For the best performance and longest life, we recommend RadioShack alkaline batteries.

Cautions:

Use only fresh batteries of the required size and recommended type.

Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

1. Slide POWER toOFF.

2.Press the tabs on the battery compartment cover on the bottom of the keyboard and pull up the cover to remove it.

3.Place the batteries in the compartment as indicated by the polarity symbols (+ and –)marked inside the compartment.

4.Replace the cover.

When the keyboard stops operating properly, replace the batteries.

Warning: Dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: If you do not plan to use the keyboard with batteries for a week or more, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

Using AC/DC Power

You can power the keyboard using an optional 9V, 300-mAAC or DC adapter and a size M Adaptaplug™ adapter (none supplied). All are available at your local RadioShack store.

Cautions:

You must use a Class 2 power

!source that supplies 9V DC and delivers at least 300 mA.

Its center tip must be set to positive and its plug must fit the keyboard's

jack. Using an adapter that does not meet these specifications could damage the keyboard or the adapter.

Always connect the AC or DC adapter to the keyboard before you connect it to AC power or vehicle battery power. When you finish, disconnect the adapter from AC power or vehicle battery power

Preparation

before you disconnect it from the keyboard.

1.Slide POWER toOFF.

2.Set the AC or DC adapter’s voltage switch to 9V.

3.Insert the Adaptaplug adapter into the adapter’s cord so it reads + TIP.

4. Connect the AC or

DC 9V

DC adapter’s bar-

 

rel plug to the DC

 

9V jack on the

 

back of the key-

 

board.

 

5.Plug the AC or DC adapter’s other end into a standard AC outlet or your vehicle’s cigarette-lightersocket.

CONNECTING

HEADPHONES

To listen to your keyboard without disturbing others, you can connect an optional pair of stereo headphones with a 1/8-inch(3.5-mm)plug. Your local RadioShack store sells a wide selection of headphones.

Insert the headphones’ plug into the PHONE jack on the back of the keyboard.

Note: Connecting headphones disconnects the keyboard’sbuilt-inspeakers.

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 volume levels. Extended high-volumelistening can lead to permanent hearing loss.

Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

CONNECTING AN EXTERNAL AMPLIFIER

To amplify your keyboard’s sound, you can connect it to an optional external amplifier using an audio cable with a 1/8-inch(3.5-mm)plug (not supplied).

To connect an external amplifier to your keyboard, insert the cable’s plug into the PHONE jack on the back of the keyboard, and connect the cable’s other end to the amplifier’s input jack(s) (such as AUX IN or TAPE IN).

Your local RadioShack store sells a full line of amplifiers, speakers, and connection cables.
