Chapter 5 RADIO TUNING AND PROGRAMMING 1.0 Introduction This chapter provides an overview of the Customer Programming Software (CPS) and tuner program which are designed for use in a Windows 95/98 environment. These programs are available in separate kits as listed in the Table 5-1. An Installation instruction manual is also included with each kit. Ta b l e 5 - 1Software Installation Kits Radio Tuning Setup 2.0 Global Radio Tuning Setup A personal computer (PC) using Windows 95/98 and a global tuner program are required to tune the radio. To perform the tuning procedures, the radio must be connected to the PC, radio interface box (RIB), and test equipment shown in Figure 5-1.
