Check COMPUTER I/O shorting pin 3 and pin 5 on the COMPUTER socket, check with
the oscilloscope a 4Vpp (1Mhz) signal on pin 1, set volume to half stroke.

The instrument generates a 1KHz sinusoidal signal in both audio channels reading
data from 104043 ROM. VOLUME controls the amplitude of signal and TRANSPOSE b
and # buttons controls the frequency from 10Hz to 2756Hz.

Re-set the frequency at 1KHz and check HEADPHONES and AUX outputs with the
oscilloscope inserting a stereo jack in the left phones socket (speakers will go be
silent) and two mono jack in the AUX OUT sockets and set volume to its maximum.
Now verify the following level of signals:
Phones output without load = 5,7±1.1Vpp
AUX output = 0,8±0,16Vpp
Set the VOLUME to minimum.
Apply a sinusoidal signal of 0.730Vpp at 1KHz with a generator to the AUX IN left and
right sockets and verify the signal output:
AUX output = 1,35±0.07Vpp
The instrument generates a tone signal in both audio channels reading data from
104023 ROM.
