Otherwise, tuning of VOR and localizer frequencies is  accomplished with the same knobs and switches, and the CDI  indicates “on course” as it does on a VOR radial. Though some GS receivers are tuned separately, in a typical  installation the GS is tuned automatically to the proper  frequency when the localizer is tuned. Each of the 40 localizer  channels in the 108.10 to 111.95 MHz band is paired with a  corresponding GS frequency. When the localizer indicator also includes a GS needle, the  instrument is often called a cross-pointer indicator. The  crossed horizontal (GS) and vertical (localizer) needles are  9-39
