4.5 UNIQUE PMR (EUROPEAN) SCREENS

4.5.1 GENERAL

Selecting LMR or PMR in the Model menu (see Section 4.4.6) affects what parameters are displayed in some screens and also what additional screens are dis- played. Basically, selecting the LMR (U.S.A.) model displays parameters for the 2-tone option, and select- ing PMR (European) displays parameters for the 5-tone option.

NOTE: Optional 2/5-Tone Kit, Part No. 585-7500- 026, is required to have the 5-tone function.

4.5.2 UNIQUE PMR SCREENS

The following menus and screens are different for LMR and PMR models:

Screen Menu - The LMR menu is described in Sec- tion 4.4.3, and the PMR version is shown below.

.

Memory Channel Screen - The LMR version of this screen is shown in Table 4-1, and the PMR version is shown in Figure 4-2. Refer to on-line help for infor- mation on unique PMR parameters (press F1 with the parameter highlighted).
