bl Built-in speakers

bm PHONES/OUTPUT jack

For connection of optional headphones, audio amplifier or keyboard amplifier. Connecting headphones automatically cuts speaker output.

bn AC adaptor jack

For connection of optional AC adaptor.

NOTE

A click (which is actually the Tone “TYPEWRITER”) sounds whenever you press the VOLUME buttons, TEMPO buttons, PATTERN SELECT button, or TONE select buttons. This sound helps you confirm that your entry was properly registered. In the case of the VOLUME and TEMPO buttons, if you press a button and the click does not sound, it means that the setting is already at its minimum or maximum.

Playing the Demonstration Tunes

Five different demonstration tunes showcase all of the characteristic features and functions of the keyboard. Simply press one of the DEMO buttons 6, and listen to the keyboard play.

*The selected demonstration tune is played in an endless loop. Press one of the DEMO buttons again, or the STOP button to stop the tune.

*You cannot use the keyboard and adjust the tempo while the demonstration tune is playing.

*You can adjust the level of volume but a click (Typewriter sound) doesn’t sound.

Output of a tone different from the one that is selected

Abnormal rhythm pattern and demo tune play

Sudden loss of sound output

DANGER

Alkaline Batteries

Perform the following steps immediately if fluid leaking from alkaline batteries ever gets into your eyes. 1.Do not rub your eyes! Rinse them with water.

2.Contact your physician immediately.

Leaving alkaline battery fluid in your eyes can lead to loss of sight.

CAUTION!

Misuse of batteries can cause them to burst and leak fluid, creating the danger of personal injury, or damage to or discoloration of clothing, furniture, etc. Be sure to note the following important precautions whenever handling batteries.

Make sure that the (+) and (–) ends of the batteries are facing as indicated by the markings on the keyboard.

Be sure to remove batteries from the keyboard whenever you do not plan to use it for a long time, such as before going on a trip, etc.

Never mix batteries of different types.

Never mix old batteries with new ones.

Never dispose of batteries by burning them. Never allow the (+) and (–) ends of batteries to become connected to each other, do not try to take batteries apart, and do not expose batteries to heat.

Remove batteries from the keyboard immediately after they show signs of losing power.

Never recharge batteries.

AC Power

AC Adaptor

 

To power the keyboard from an AC outlet, you need an AC adaptor and a size M AdaptaplugTM (neither supplied, available at your local RadioShack store or online www.RadioShack.com).

Back

Household power outlet

CAUTION!

You must use a class 2 AC power source that supplies 7.5V DC and delivers at least 300 mA. Its center tip must be set to negative and its plug must fit the keyboard’s DC 7.5V jack. Using an adaptor that does not meet these specifications could damage the keyboard or the adaptor.

WARNING!

Take care to avoid damage to the power cord. Never place heavy objects on the cord and keep it away from heat. A damaged power cord creates the danger of fire and electrical shock.

CAUTION!

Always unplug the AC adaptor from the power outlet if you do not plan to use the keyboard for a long time, such as when leaving on a trip, etc.

When not using the keyboard, turn off power and unplug the AC adaptor from the power outlet.

IMPORTANT!

Be sure that keyboard power is turned off before connecting or disconnecting the AC adaptor to it.

The AC adaptor may become warm to the touch after long-term use. This is normal and does not indicate malfunction.
