I have an OCTEL 250, system went into re-boot loop last night. One fan is oos, rebooted and bypassed alarm, time and date is correct on system. Now when a message is left and user checks message system says date: Jan 1 1984 time: 2:11 pm or some time near that.Also says the message is archived and wll be deleted? Can the system be re-booted and set to previous yr/date previous to 2015? like 2009?
