Chapter 3 Radio Tuning 3.1 Introduction This chapter provides an overview of the software and hardware tuning material available for the Business Portable Radio. The Business Portable Customer Programming Software and Tuner Software are designed for use in a Windows 95/98/NT/2000/XP environment. This software covers all the functions of the traditional Radio Service Software (RSS) package. An Installation instruction manual is contained within each kit. 3.2 Software Tuning Setup A Windows 95/98/NT/2000/XP PC (personal computer) and Tuner are required to tune parameters such as power, sensitivity, squelch and RSSI. To perform the tuning procedures, the radio must be connected to the PC and IF Test Set as shown in Figure 3-1. Refer to online help files for specific tuning procedures. See Figure 3-2, how to attach the radio. Description Kit Number Customer Programming and Tuning Software (CD)RVN4196_ Figure 3-1.

Insert the antenna ground plate (DSK001C719) through the antenna adaptor (HLN8262). Figure 3-2. 2. Screw the antenna adaptor into the radio’s antenna jack as shown in Figure 3-3. Figure 3-3. Note: Make sure the antenna ground plate is placed properly before the battery eliminator is inserted to the radio. This is to ensure that the radio has a better grounding.
