Mounting the Tracker Pro on the Vantage Lite

You will need the new mount and the Tracker Pro to proceed.

Remove the handle from your Vantage Lite by unscrewing the two screws that hold it to the case. Put the handle and the screws that are in it, in a safe place in case you want to use it again.
Remove the new mount from the plastic bag.
Mount the Tracker Pro Mount
As you look at the front of the Vantage Lite: the small screw in the mount fits into the hole on the top right where the handle used to be.
Tighten the screw so that the mount sits securely on the top of the Vantage Lite.
If you ordered a Tracker Pro with your mount, remove it from its box.
If you already have a Tracker Pro, you will need it now.
Insert the metal ball into the larger screw on the mount. Tighten the screw.
You can loosen the screw a little if you need to rotate the Tracker Pro.
Plug the end of the cable coming from the Tracker Pro into the USB port on your Vantage Lite.
The Tracker Pro is now mounted on the Vantage Lite.
