HPS-1478

 

 

 

 

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.
