Notes:
1. For optimum performance, order replacement diodes, transistors, and circuit
modules by Motorola part number only.
2. When ordering crystals, specify carrier frequency, crystal frequency, crystal
type number, and Motorola part number.
3. Part value notations:
p=10
-12
n=10
-9
µ=10
-6
m=10
-3
k=10

4. ITEM refers to the component reference designator.
5. The VOCON Board uses a 6-layer printed circuit board.
