If I understand right:
this P Instrument in SA-3B is not for range boresight indication,
as it could be understand in Page-12 of the SA-3B_English manual, but it's for the Course Parameters

I check the manual again, this instrument is mentioned only when we want to use or lock range boresight,
and in Page-37 it's not clear if this manual told about range or Course Parameters,

will be happy if any one can confirm that, and have more info about this Course Parameters.
