Power and Connection Via USB
1. Check that the on/off button on the back of the unit is set to �OFF.� 2. Plug the USB cable provided with your Keystation keyboard to a free USB port on your computer. 3. Plug the other end of the USB cable to the USB input on the Keystation keyboard. The single USB cable not only powers the keyboard but also sends MIDI data to and from your computer system.

Using an External Power Supply
You can also use a power adapter (not included) with the following speci�cation: 9V DC output, 250- 300mA, center positive. Make sure you are not already powering the Keystation via USB�if you are receiving power from the USB hub, no external supply is needed. If not, then simply plug the power supply in to the �DC 9V� input and switch the power on. Note: Do not leave the adapter plugged in for long periods of time if the unit is not in use.

Windows XP and Mac OS X
If you are using Windows XP or Mac OS X, you can now simply move the keyboard�s power switch to the �ON� position. Because the Keystation line of keyboards is class compliant, the unit will work without any further installation.

Other Operating Systems
If you are using an operating system other than Mac OS X or Windows XP, please refer to our website at www.m-audio.com for the latest Keystation drivers for Macintosh or Windows operating systems.
