The pump displays the Watson-Marlow start-up screen for four seconds,
followed by the pump model identity screen for four seconds, and then the
manual mode main screen.
The rotation symbol on the display indicates clockwise rotation. The default
speed setting is 165rpm, but 265rpm is available (see 18.13 Set maximum
allowed speed). Other initial start-up operational parameters are listed in the
