					radio station on a station preset. You can   
					adjust the volume level of this beep.   
					Radio operation   
					This car audio system has been   
					equipped with an RDS radio receiver.   
					Many FM radio stations now transmit   
					the RDS signal, which contains such   
					other information as the station name   
					and the program type (PTY) along with   
					their regular station programming.   
					As soon as the car radio receiver de-   
					tects the station name, it will appear in   
					the display. It is also possible to display   
					the program type. For more information,   
					refer to the section on “Program Type   
					(PTY)”.   
					● Press MENU 8.   
					● Press : repeatedly until   
					“BEEP” appears in the display.   
					● Press   
					: to adjust the volume.   
					“0” means the beep volume is off,

					al) improve the performance of your car   
					radio.   
					● AF. If this RDS function is activated,   
					the car radio continuously searches   
					in the background for the frequency   
					with the best reception for the sta-   
					tion you have tuned into.   
					● REG. A number of radio stations   
					broadcast different regional pro-   
					gramming at different times of the   
					day. Use REG to prevent your car   
					radio from tuning into alternate fre-   
					quencies which might have differ-   
					ent programming.

					the seek tuning function to tune the ra-   
					dio into stations with strong reception   
					signals only, or to those with weaker   
					reception signals as well.
