1) When extended memory is used, a large part of the base memory can be used to store RAM texts and DBs (text/
DB addresses ≥ 4000)
2) The period given is a buffer time; it is dependent on the ambient temperature (a higher temperature means a
shorter buffer time)
3) The 1 kHz applies with a pulse/pause ratio of 1:1 and refers to the total frequencies of the two inputs
4) The 1 kHz applies with a pulse/pause ratio of 1:1
