800/900 MHZ (800–900 MHZ) INFORMATION
1.0 Allocation of Schematics and Circuit Boards
1.1 Controller Circuits
The 800/900 MHz Band circuits are contained on the Printed Circuit Board (PCB) which also
contains the Controller circuits. This Chapter shows the schematics for the 800/900 MHz Band
circuits only, refer to the Controller section for details of the related Controller circuits. The PCB
component layouts in this Chapter show both the Controller and 800/900 MHz Band circuit
components. The 800/900 MHz Band schematics and the related PCB and parts list are shown in
the tables below.
