These switches specify a privileged display. The term privileged display means the display which is
resumed in five seconds after any other display is selected, if no key is pressed.
The PRIO1 and PRIO2 switches can determine the privileged display only when the NOCLK initial setting
diode = 0 (with a clock). If NOCLK = 1 (without a clock), the states of these switches are ignored.

None Display switching occurs when the DISP key or a preset number
key is pressed.
In radio mode
Each time the DISP key is pressed, switching occurs between
the frequency and clock displays.
Pressing a preset number key during clock display causes the
frequency display to appear.
In tape mode
Each time the DISP key is pressed, switching occurs between
the “ ” and clock displays.
In CD mode
Each time the DISP key is pressed, switching occurs between
the “ ” and clock displays.
In radio-monitor tape mode
Each time the DISP key is pressed, switching occurs among
the “ ”, frequency, and clock displays.
Pressing the preset number key during “ ” or clock display
causes the frequency display to appear.
Radio-monitor tape mode begins with the frequency display.
In radio-monitor CD mode
Each time the DISP key is pressed, switching occurs among
