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

Connecting Headphones or an External Music
Amplifier
PREPARATION
Set the volume level low before connecting
headphones or an external amplifier. This
protects against possible hearing damage due
to sudden loud-volume output.
Headphones
Connecting headphones cuts off output from the
speakers, so you can play without disturbing those
around you, even late at night. Be sure to use
headphones that have a mini plug.
Music amplifier, audio equipment, etc.
It is up to you to provide a commercially available cord to connect to a music amplifier or other external
equipment. Make sure the cord you use has a mini plug on the end you connect to this keyboard.
