Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of t

12、he memory during power failures and even when the unit is un-plugged. The unit must be plugged in order to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the average, memory contents are protected

13、over a period of a few weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid cli-mate. 5. Changing the AM band step With the exception of the worldwide models, a tuning step selector switch is not provided. When you change the band s
