5 OPERATION
On power up a default or custom splash screen appears and remains visible whilst the unit is
initialising. If during this process a network broadcast storm is detected, the unit stops, displaying a
network failure icon until the broadcast storm has cleared, after which the initialisation process
resumes.
5.1
INTRODUCTION
The operator interface consists of a display screen and four push buttons.
5.1.1 Display Screen
The display screen is used both to display channel information (in one of a number of display modes), and to
display the various configuration screens which allow the user to setup the recorder to display the required
channels, to set up alarms and so on. Display modes are described in Section 5.4 below; configuration is
described in Section 6.
In display mode, the screen is split horizontally into three areas (Figure 5):
1.
a faceplate giving channel details.
2.
the main display screen showing channel traces etc.
3.
the status area, displaying instrument name, the current time and date and any system icons.

In configuration mode, the entire display screen is devoted to the selected configuration menu.
5.1.2 Navigation Pushbuttons
There are four navigation buttons, called 'Page', 'Scroll', 'Lower' and 'Raise' located below the screen. The
general properties of these buttons are described in the remainder of this section, but some have additional,
context sensitive functions, which, for the sake of clarity are not described here but in the relevant sections (e.g.
'Message summary') of the manual.
