ADJUSTMENT
CPU CLOCK
Connect scope to TP-1 .
Adjust IFT1 for 2.2ius/cycle.
INT CLOCK
Connect scope to TP-2.
Adjust TM-1 for 1.8ms/cycle.
TEMPO CLOCK
Connect scope to TP-3.
Set TEMPO knob at FAST.
Adjust TM-2 for 8ms/cycle.
Confirm that period of 1 cycle becomes
65ms when TEMPO is set at SLOW.
NOISE GENERATOR
Connect AC voltmeter to TP-4.
Adjust TM-4 so that the reading is 130mV (rms).
