HUD Image defects are explained as follows:

• Image 1 is compressed, (windshield installed incorrectly)
• Image 2 is duplicated, (wrong windshield installed)
• Images 3 and 4 are distorted, the HUD has been fitted incorrectly

The image is blanked out by light striking the windshield or the HUD in unfavorable light conditions. Excessive heat in the HUD will also cause the image to fade.
