  1. Y signal (TS7)
With [VOLUME+/-] buttons of the remote control transmitter, adjust the value appearing below YGAIN indication so that the
value below MAX indication becomes D4. When adjusted, measure the amplitude between pedestal and white peak.
  2. B-Y signal (TS8)
With [VOLUME+/-] buttons of the remote control transmitter, adjust the value appearing below B-Y indication so that the
amplitude (yellow-blue) at TS8becomes equal to the value measured in the YGAIN adjustment.
  3. R-Y signal (TS9)
With [VOLUME+/-] buttons of the remote control transmitter, adjust the value appearing below R-Y indication so that the
