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. SIDE refers to the loca-
tion of the component on the board; S1=Side 1, S2=Side 2.
5. The VOCON Board Kit uses a 6-layer printed circuit board.
