Selection precautions

Parts included:
Colored plates (white, red, green, and orange), a legend plate (transparent), and a light baffle (split-screen models only) are included. Use the appropriate combination for the LED coloring required.

The number of white colored plates required to enable colored illumination for the corresponding screen-split configuration is included. (For example, 4-split screen models include 4 white colored plates).

The number of colored plates included for each model are shown in the following table.

A3P Lineup 30

* The following types of colored plates are included with Horizontal and Vertical 3-splitScreen Switches.
  White: One colored plate for a 2-split screen and two colored plates for a 4-split screen.
  Red, green, or orange: One colored plate for a 2-split screen and one colored plates for a 4-split screen.
