Sorry, I re-read the original question ... the UNAVAILABLE appears within the display when you're trying to adjust the pitch on the NON-MASTER deck because the SYNC is currently engaged. If you want to make both tracks faster or slower, use the master deck or switch the master deck. If you want to adjust the pitch independently, disable the SYNC then use the software pick-up to go to the value the pitch is currently at, then change the pitch as desired.
