Changing the Track Stick Cap
You can replace your track stick cap if it wears down from prolonged use or if you prefer a different
color. You can purchase additional caps by visiting the Dell website at www.dell.com.
1. Pull the cap off the track stick.
2. Align the new cap over the square track-stick post and gently press the cap down onto the
post.
NOTICE: The track stick can damage the display if it is not properly seated on the post.
3. Test the track stick to ensure that the cap is seated properly.
