242 tones

Choose from among orchestral sounds, synthesized sounds, and more.

100 rhythms

100 versatile rhythms help to add plenty of life to all your keyboard performances.

Auto Accompaniment

Simply play a chord and the corresponding rhythm, bass and chord parts play automatically.

PIANO BANK button

The touch of a button takes you directly to piano tones and piano lessons.

3-Step Lesson System

The 3-Step Lesson System lets you practice at your own pace. The keyboard automatically grades your performances, so you can trace your progress as you improve.

•3-Step Lesson System: Now you can learn the parts that make up the keyboard’s built-in tunes. Guidance that appears on the monitor screen helps lead you down the path to music proficiency.

•Evaluation System: The keyboard can be configured to rate your performances during Step 3 lesson by assigning points.

100 built-in tunes, including piano pieces

Built-in tunes are divided into two groups: a Song Bank of 50 tunes with Auto Accompaniment, and a Piano Bank of 50 piano tunes.

Musical Information System

A big LCD screen graphically shows you fingerings, keyboard keys to be pressed, and notes, making keyboard play more informative and enjoyable than ever before.

Avoid heat, humidity or direct sunlight.

Do not overexpose the instrument to direct sunlight, or place it near an air conditioner, or in any extremely hot place.

Do not use near a TV or radio.

This instrument can cause video or audio interference with TV and radio reception. If this happens, move the instrument away from the TV or radio.

Clean the keyboard with a soft cloth dampened in a weak solution of water and a neutral detergent. Soak the cloth in the solution and squeeze until it is almost dry.

Avoid use in areas subjected to temperature extremes.

Extreme heat can cause figures on the LCD screen to become dim and difficult to read. This condition should correct itself when the keyboard is brought back to normal temperature.

NOTE

•You may notice lines in the finish of the case of this keyboard. These lines are a result of the molding process used to shape the plastic of the case. They are not cracks or breaks in the plastic, and are no cause for concern.
