LOW BAND PCBS/SCHEMATICS/PARTS LISTS
1.0 Allocation of Schematics and Circuit Boards
1.1 Controller Circuits
The Low Band circuits are contained on the Printed Circuit Board (PCB) which also contains the
Controller circuits. This Chapter shows the schematics for the Low Band circuits only, refer to the
Controller section for details of the related Controller circuits . The PCB component layouts and the
Parts Lists in this Chapter show both the Controller and Low Band circuit components. The Low
Band schematics and the related PCB and parts list are shown in the tables below.
