A box will appear in the bottom right corner indicating which memorybank the
unit is in, I.E. “MEMORYBANK 1”. Next press a number (1-8) representing
which memorybank the new screen size will be assigned to. The new memorybank

If this feature is OFF, then each of the 32 memories will be scan rate dependent, in other words, each of 32 memories MUST have a different frequency. This is especially useful for use with computers and their different resolutions.
