1 0 01 01 Set the data.
2 D 92 Change the data and set the VCO
frequency (f) to the specified value.
3 D 92 Press PAUSE button.
4 D 92 Read the data, and this data is
named D92.
5 Convert D92 to decimal notation,
and obtain D92’. (Note2)
6 Calculate D93’ using following
equations (Decimal calculation)
NTSC model:
When D92’ 230
D
93’= D92’+ 25
When D92’ > 230
D93’= 255
PAL model:
When D92’ 25
D93’ = D92’– 25
When D92’ < 25
D93’ = 00
7 Convert D93’ to a hexadecimal
number, and obtain D93. (Note2)
8 D 93 D93 Set the data, and press PAUSE
button.
9 0 01 00 Set the data.
