Important recommendations
1.1
Before beginning the adjustments, the TV set should be a pre-heated during at least 15
minutes.
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.
