The display of PF22 consists of 2 lines of 24 characters each and has constant background
lighting.
There will always be a blinking cursor on the display showing where a character will appear, if a
key is activated.
The top line is the prompt line where PF22 communicates with the operator.
The bottom line is the status line that always shows the current operating parameters. This status
line can be scrolled by pressing the UP or DOWN ARROW of the keyboard.
When operating PF22, it is VERY important to watch the top line constantly, as any current
question or instruction will be displayed here.
