6.2. Cautions for Adjustment

- Never turn off the MAIN POWER switch until every fan completely 

stops.

- To maintain and ensure safety, always use the designated 

components for replacement parts.

- If removing any clamps, lead wires or connectors, always place 

them back in their proper locations.

- Be careful not to damage the lead wires or components when using 

a soldering iron or similar tool.

6.3. Setting Before Adjustment

- Set up the projector to obtain the projection distance below.
- Turn the zoom knob of the lens block to obtain the largest size of 

the picture.

6.4. Convergence Adjustment

6.4.1. Basic Adjustment Procedure

1. Use a hexagon head wrench, loosen the 2 screws just until the 

bracket can be moved by your fingers.
