The first switch controls the filter setting. The words allowed in the tolerant mode are filtered out, plus approximately 100 other offensive words and phrases are removed. The second switch is the closed-caption switch. It controls what happens when an offensive word is detected. The closed-caption text is not displayed.
All dialog is closed-captioned.
TVGuardian still automatically removes the offensive language from both the audio and closed-captioning. Only When an offensive word or phrase is detected, TVGuardian will display the text for the muted phrase. However, the offensive word or phrase is removed and a substitute word is put in its place when appropriate. The strict filter setting also filters the words God, Jesus, and Christ when used as an expletive. TVGuardian comes with a one year warranty on parts and labor.
