Fail-Safe Function

The center display unit performs the fail-safe control when the system detects an abnormal high temperature in the unit:

• When the center display unit temperature rises over 176 deg.F (80 deg.C), the center display unit sends the error status to the audio unit, and the center display unit displays the error message and then the display back light turns off (the background system stay on).
• When the center display unit temperature drops to below 167 deg.F (75 deg.C), the display back light turns on, and the display brightness returns gradually with the temperature drops.
