carolann3750 0 Posted December 4, 2016 have a CE RoHS KPD674ZB with 4 cameras in use. for some reason the password will not be accepted and have tried numerous things, maybe not doing them right. Help! Took the battery out, replaced it, help down button and got single beep but then went to cameras and when try to put in ANY password it says incorrect. Any suggestions?! Hope so!
