Loosen Screws and Understand Mounting for Screwdriver-Required Blinds

What happens here

Locate the three Phillips head screws on the back side of the blind's headrail. These screws hold plastic tabs that secure the blind. Using a Phillips head screwdriver or drill, loosen each screw approximately halfway. Avoid removing the screws entirely, as a small plastic piece might fall out, requiring reinsertion. Ensure the plastic tab holding the blind is facing outward, as this orientation is crucial for reinstallation to catch the top part of the blind.

Goal: Safely loosen mounting screws and understand the tab mechanism.
