Unless otherwise noted, controls and switches on the
outside of the Satellite should be set in the following "normal"
positions for testing:

1. A djust R4 until the +9 volt line is exactly 9.000 volts
+10 mv. Verify that the -9 volts line is -9.000 volts
+200 mv.
/
2. Depress highest note on keyboard. Observe the voltage between
A6 (common lead) and AS (positive lead). Adjust R79 until
voltage reads +9.000 volts +10 mv. This sets the keyboard
current.
3. Verify that the trigger voltage at the collector of QB is as
shown in Fig. 6 when a single key is depressed. Hold that
key down and depress the next highest key and verify that a
trigger occurs.
4. Verify that the keyboard pitch voltage at the emitter of Q2
goes from -4.50 volts to +4.50 volts +50 mv as the tester
runs his hand up the keyboai'd. Also verify that this voltage
holds while and after the key is released and does not drift +
more than 25 mv per minute.
5. Depress "one octave" tab and the A above middle G on the
keyboard. Observe a sawtooth wave as shown in Fig. 7 at the
emitter of Q46. Adjust tune control to approximately the
. middle range. Adjust R16 for approximately 440 Hz.
6. Depress the C above middle G and adjust its frequency by means
of the fine tuning control to some convenient value, say 500 Hz.
Now play the lowest C on the keyboard and adjust R17 for pre¬
cisely 125 llz. Repeat until a precise two octave step results
between these two C's. This sets the overall interval spacing.
7. Depress the lowest C. Observe that the frequency is precisely
125 Hz. Raise the "one octave" tab, and adjust R10 for pre- •
ciscly 250 Hz. This sets the one octave step.
