How do I import a license key or load a voice to a Tyros4 using a USB storage device?

Insert your USB storage device containing your license key or voice into the USB port on your instrument (located just to the right of the keyboard).
To import the license key, press and hold [DIRECT ACCESS], and then press [EXPANSION] to display the Owner Screen.
Press [J], then [G] to import the License Key.
When importing is complete, the upper portion of the OWNER page will display the message: License Key: REGISTERED
Press [G] to confirm installation.
Your instrument is now licensed. You may skip this step next time you load a Voice on this instrument.
Now, let's load the Voice. If you are loading more than one Voice pack, you will need to repeat the following steps for each pack.
Press [FUNCTION] on your instrument. (located under Menu, to the right of the center screen)
Press [J]. Your Tyros will now display the Pack screen.
Select the desired folder of the Pack or Voice you wan to install by pressing the button next to it one time.
Press [F] to continue.
Press [G] to install the pack. Do not disconnect your USB storage device from the instrument. You must leave it connected to use your instrument. It may take a few minutes to complete the loading process. Once installation is complete, press [G].
