Install the URC as follows:
1. Use the URC trunnion as a template to mark the mounting holes; 
drill 5/32" holes. If mounting on a plastic surface, use a metal backing plate.
2. Attach the trunnion bracket using all four 10 – 16" x 5/8" self-tapping screws provided.
3. Temporarily install the URC (adjust for proper viewing angle) and fasten it to the trunnion with 
two wing screws. Test the installation to ensure that the unit is securely locked in place.
