ALARM MEMORY FUNCTION

(a) If the alarm is set off (tampering is detected) while the theft deterrent system is in the armed state, it will be stored by the alarm memory function. Whenever the theft deterrent system is canceled, the alarm memory function causes the taillights to light up for 2 seconds in order to inform the user that the alarm has been set off.
