I have Alpine cassete/CD Player in my car & its Demo button's light turned red. How will it become green?

Question

The system is installed in my car and the Demo light actually is green. However, recently somehow it has turned red and I don't know what has happened.

Answer 1

There's probably a setting in the setup menu that allows you to change the color. If you provide a model number, we may be able to give you more information.
