HPS-2971 4. CALIBRATION GUIDE Note: This guide is only an orientation and, for some items, may be adapted by Factory Engineering to best conform to the productive process. INTRODUCTION Note: ü It is necessary to pre-heat the TV during 15 minutes, before its calibration.
Page 24
HPS-2971 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.
