To verify that your computer is running the necessary Apple 
Audio Extensions, close all open applications. On the desktop, 
find the icon that corresponds with your Macintosh hard drive. 
Double click on it. A window will open listing all the files and 
folders on your hard drive. Scroll down and find the System 
Folder icon. Click on the arrow to the left of the System Folder 
icon so that all the folders contained in the System Folder 
become visible. Scroll down until you find the Extensions 
folder and click on the arrow to the left of the folder icon. In the 
files that are listed in the Extensions folder, scroll down and 
verify that a file Apple Audio Extension appears. Check that the 
version of this file is 1.0.5 or higher. If a version column does not 
appear, go to View in the top navigation bar and select View 
Options
. Place a check next to Version in the Show Columns 
section. Click on OK. A version column will now appear and let 
you check the version of the Apple Audio Extension file running 
on your computer. If your system is not running Apple Audio 
Extension 1.0.5 or higher, the Digital PCLink, may not operate.

After verifying your computer has the necessary operating 
system and audio extensions, close all applications. Plug the 
supplied USB cable into a USB port on your computer. Now plug 
the Digital PCLink into the other end of the USB cable. Do not 
plug the Digital PCLink into a USB hub, as other devices on the 
hub may effect the digital audio data running to the Digital 
PCLink causing unwanted pops and clicks in your recordings.

Your computer will now automatically initiate the Digital 
PCLink and set it as the preferred playback device. After a few 
seconds, you should notice that the Digital PCLink red 
TOSLINK light is activated. If the Digital PCLink’s TOSLINK 
light does not activate after a few seconds, verify that you are 
running the minimum operating system and Apple Audio 
Extensions requirements. The installation of your Digital PCLink 
is now complete. Please proceed to the next section, “Recording 
to MiniDisc” (page 11).
