Remove the secondary fuses F1, F2, F3, located on POWER AMPLIFIER & SUPPLY
BOARD; turn on the instrument and verify the supply AC voltages:
(CN6) between pin1 and pin2 = 27,5±1,5Vac
(CN6) between pin1 and pin3 = 27,5±1,5Vac
(CN6) between pin2 and pin3 = 55±3Vac
(CN12) between pin1 and pin2 = 16±0,8Vac
(CN12) between pin1 and pin3 = 16±0,8Vac
(CN12) between pin2 and pin3 = 32±1,6Vac
Turn off the instrument, and put the fuses back on its holders.
Turn on the instrument and the appropriate welcome message appears on the display.
A few seconds later the led GRAND PIANO light.
Check the supply DC voltages on CPU & SOUND GENERATOR BOARD:
(CN8) between pin9 and pin7 = +5±0,25Vdc
