While viewing the SER events, front-panel pushbuttons provide navigation
and control functions as indicated in Tabl e 7.7.
Hold down either the Up Arrow or Down Arrow to achieve accelerated scrolling.
Holding down the Up Arrow or Down Arrow navigates one screen at a time for
the first five screens, and then increases to five screens at a time if the button
remains pressed. Accelerated scrolling stops at the newest or oldest SER event
record available, depending on the direction of the scrolling.
When the upper limit of the SER events is reached, press the Down Arrow one
more time and the report will wrap around to display the screen containing the
first SER event. Similarly, when the lower limit of the SER events is reached,
press the Up Arrow one more time and the report will wrap around to display
the screen containing the last SER event.
