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. “Not Placed” means that components are for future use, and are not 
placed on the circuit board at this time.

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. “Not Placed” means that components are for future use, and are 
not placed on the circuit board at this time. REFERENCE
