# Install Survey3 into PRO Housing

The Survey3 PRO housing works with the default lens surround spacer as well as with the Manual Lens  Focus Wheel. All 12 models of the Survey3 camera are supported.

1. If your Survey3 camera has the Manual Lens Focus Wheel installed then remove the default lens surround spacer by rotating it counterclockwise and pulling it out:

2. To install the (optional) desiccant packet pull the shelf down and push the packet into the cavity. You can route the GNSS (GPS) wires under the back of the shelf to help get them out of the way.

3. Plug the cables from the Survey3 PRO housing into the camera. The USB with the green wire is the GNSS (GPS) plug.&#x20;

4. Tilt the camera down to clear the top lip, notch the camera pull tab into the slot on the bottom and push it into the housing. As you push it in, make sure no wires are pulled inward.

5. Push the cables inward and away from the camera to make room for the Switch Door. Once the cables are out of the way reinstall the Switch Door by holding the tab until it is seated correctly. You may need to wiggle the tab on the Switch Door until it clicks into place.
