Setup Guide
1. Physical Placement and Adjustment
The WiMiUS S27 features a unique 2700 adjustable built-in stand, allowing for versatile projection angles, including ceiling projection. Position the projector on a stable surface. The 1/4'' screw hole on the bottom also supports ceiling and wall mounting for greater flexibility.

Figure 1: The 2700 adjustable stand allows for flexible projection angles.
For optimal image size relative to distance, utilize the 0.98:1 true short throw ratio. This allows for a 100-inch screen from a shorter distance compared to traditional projectors, reducing optical distortion.

2. Power Connection
Connect the provided power cord to the projector's power input port and then to a standard electrical outlet. The S27 projector is not battery-powered and requires continuous power during use.
3. Image Adjustment
The projector features Auto Vertical Keystone Correction to automatically adjust the image for a perfectly rectangular display, even if the projector is angled. You can also manually adjust focus using the focus ring on the lens.

For fine-tuning the image size without moving the projector, use the Zoom Out function, which allows adjustment from 100% down to 85%.
