Title: Hyundai HCT-7440 Lock although no child lock
Post by: Jaype on January 30, 2009,11:31:51

Has anyone had this problem?  My Hyundai 74cm when switched on just display LOCK.  I've read the manual but there is no reference to a child lock.  I am bowled out on this one :sad:. Maybe someone knows how to unlock it. That would make my day :clap:
