Red light indicates an unusually low battery charge so the unit is not charging. The dock or other hardware including the battery may be defective. Instead of analyzing it, if possible return it for exchange.
A red light when starting is not usual, as the battery would normally be delivered sufficiently charged to begin in the orange light phase. Perhaps this system is rejecting a defective battery. When it does appear the red phase usually disappears in a few minutes, while hours can be spent in orange and green blinking.
