Note: Key the radio while making adjustments or measurments.

1.1 GENERAL

Perform all adjustments at a supply voltage 13.2 ~0.1 volts dc, unless the instruction call for a

different voltage.

Interpret instruction to turn controls clockwise (CW) or counterclockwise (CCW) to mean »as viewed

from the component side of the circuit board«.

Picture A and B show the locations of the components.

When you perform any of the tune-up procedures given in sections 1.2, 1.3, 1.4 and 1.5, the radio

must be completly assembled except for the chassis cover, top cover of the synthesizer compartment,
