Format the USB-Stick by selecting 'FORMAT' in the menu. You have to make a choice to format either the USB-Stick or the internal memory. Choose 'USB Flash' and push 'ENTER'. Switch OFF the instrument and remove the USB-Stick. Your USB-Stick is now ready for use with the XK-5)
Step B: Download to your computer, Unzip and Copy to the formatted USB-Stick Insert the USB-Stick on your PC, and after unzipping the downloaded zip-file, copy the unzipped files that end with '.sys' into the 'system' folder (Hammond > xk5 > system) of the USB-Stick.
Step C: Loading the files in your XK-5 Switch on the power of your XK-5 and insert the USB-Stick in the USB-slot of the XK-5 again. Select the 'UPDATE' menu ('UPDATE' flashes), Push the 'ENTER' button, Select 'USB Flash', not the internal memory, Push the 'ENTER' button again and when the files are loaded switch OFF the XK-5 and remove the USB-Stick.
Step D: Reset your XK-5 The easiest way to do this is hold the 'RECORD' button while you switch ON the XK-5 (for the single manual version), or hold the 'BANK' button while you switch ON the instrument (for the double manual). You may now reload your presets, if you stored these before. You can check the version of the software loaded in the instrument in the SYSTEM menu. NOTE: If you try to update an XK-5 that is already up to date, you will see 'No Update File' on the screen.
