CCE HPS-2971 - Important Calibration Recommendations; Register Definitions

HPS-2971
4.1 Important recommendations
4.1.1 Before beginning the adjustments, the TV set should be a pre-heated during at
least 15 minutes.
4.1.2 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.
