Press the A channel button on the vectorscope.

This displays the sync and subcarrier phases 
(composite signals only) of the signal from player 1.

On player 1, adjust the front panel SYNC PHASE and 
SC PHASE controls, using a Phillips screwdriver, so 
that the output from player 1 on channel A is in correct 
phase alignment with the black burst signal on channel 
B.

When component signals are used the subcarrier phase 
indicator does not appear.
