A: THE ISSUE WITH SAVING THE TIME/DATE IS THERE IS A BACKUP BATTERY BUILT INTO THE BOARD. IF THE ITEMS ARE NOT POWERED ON LONG ENOUGH TO MAKE SURE THE BACKUP BATTERY IS FULLY CHARGED, IT WILL NOT SAVE THE TIME/DATE.
OR IF THE UNIT IS POWERED OFF LONGER THAN THE BATTERY TO SAVE THE TIME/DATE WILL ALSO RESET BACK TO FACTORY. IF THE BATTERY IS FULLY CHARGED, NORMALLY IT WILL SAVE THE TIME/DATE AT LEAST A COUPLE OF DAYS.
