CD Player Anti-Theft Feature Delco LOC I1 is a security feature forthe compact disc player. It can be used or ignored. If ignored, the system plays normally. If it is used, your player won't be usable if it is ever stolen, because it will go to LOC mode any time battery power is removed. Until an unlock code is entered, it will not turn on.
