Chapter 5 Radio Alignment Procedures

This chapter describes radio alignment procedures for both the receiver and transmitter.

5.1Radio Alignment Test Setup

A personal computer (PC) and tuner software (RVN4181) are required to align the radio. Refer to the Customer Programming Software (CPS) Installation Guide (Motorola publication part number 6881095C44) for setup procedures for the software, and to the on-line help in the CPS for complete field programming information. To perform the alignment procedures, the radio must be connected to the PC and to a universal test set. The radio alignment test setup is shown in Figure 5-1.
