The alignment of the A12 YTF Preselector is performed by the use of an internal
instrument routine and requires no additional test equipment. Use the
following procedure to perform the A12 YTF Preselector alignment routine:
1. If the Front End Control Test board was being used just prior to the running
of this routine turn the instrument off, disconnect the Front End Control
Test board from the instrument, and plug all of the instrument internal
cables back into the A15 Front End Control assembly.
2. Then turn the instrument on and allow it to complete its boot up process.
3. Run the A12 YTF Preselector alignment routine by pressing System,
