• 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.

Play mode
When a song is played by the app, notes and chord names appear on the Digital Keyboard’s display. You can play along with a song on the keyboard while viewing information about which keyboard keys should be pressed on the app screen. In this mode, sounds played by the app itself will sound through the Digital Keyboard’s speakers, so sounds will be different from those of the Digital Keyboard.
Store mode
