Procedures for Testing a Display with Dolby Digital or DTS Audio Test Patterns

Use the following procedures to run audio tests using Dolby Digital and or DTS audio test patterns. These test
patterns are useful for calibrating the room acoustics in a home theatre system.

1. Make the physical connections between the 780B and the audio rendering device as described in the

procedures above.

2. From the

Home

menu (shown in the figure below), select the Audio status/activation button on the Status

Bar as indicated below.

The

Audio Pattern (Test Tone)

menu appears as shown below:
