Fig. 7-4 RF Converter Types for VS-2
As might be known from Fig. 7-1, the frequency spec-
trum, etc. of the television channel vary from TV system
to TV system. Accordingly, the tuner unit of the video
cassette recorder (VCR) which receives TV broadcasts
is classified as shown in Fig. 7-2 according to the model
code letters.
VS-2EGN has a built-in tuner for Model EG.
Fig. 7-3 shows the types of AKAI VTR available and the
transmission channels used in major countries.
The types of RF converter are classified as shown in
Fig. 7-4, which shows that the RF converter for the G
system is used for the VS-2EGN. This type of RF con-
verter is also used for models EG and EO.
