3.1 Important recommendations
3.1.1 Before beginning the adjustments, the TV set should be a pre-heated during at least
15 minutes.
3.1.2 The positioning of the TV set should obey the magnetic parameters of South America
that it is -120 vertical mG. In the practice, this is gotten with a relative precision,
positioning the TV set with the face (screen) of the CRT pointing to the geographical
East.
Note: These cares should also be taken when CQ will analyze the TV set.
