DIGITAL AMPLIFIER is equipped with a back-up battery to keep clock in time during short mains power cuts. If the unit is
disconnected from the mains more than couple of days, the clock time should be checked and set again.
Note If the clock is adjusted backward in time it is needed to reboot the system.
Internal clock will automatically notice leap days and when “Use Daylight Saving Time” is checked internal clock will also
take into account the summer time.
The internal clock is used for time based events, monitoring interval and for event and error log time markings.
