Power supply

Either an AC adaptor or batteries can be used to power this Digital Keyboard. Normally, use of AC adaptor power is recommended.

Using Headphones in Casio CTK 2550

• Be sure to turn down the volume level before connecting
headphones.

• Do not listen to very high volume output over headphones for long period. Doing so creates the risk of hearing damage.

• If the plug of the headphones you are using does not match the PHONES/OUTPUT jack, use the applicable commercially available adaptor plug 6.5mm to 3.5mm converter jack.
