SunScan User Manual v 1.05 SunScan Tutorial •

• 15
Warning! If you were already in the Psion System Screen, you’ll see a message Exit
System Screen? Press N, so that you stay in the System Screen.
From this point you can launch SunData, the SunScan application, but first it is a
good idea to familiarise yourself with the Workabout’s keyboard. The main uses of
the keys are explained in the Workabout user Guide on pages 10 and 11.
The following keys are particularly important for the Workabout:
Pops up a menu of options relevant to your current activity
Move the cursor up and down menu options, or adjust the value of a set-
up parameter
Cycle through the available settings for a menu option
Carry out highlighted activity, choose menu option or accept highlighted
setting
Exit from current activity or menu, abandoning any changes
Gives you and expanded range of choices, especially in file operations
What to do if you get lost
The important thing to remember is that you can get out of any menu by pressing
On/Esc, and out of any application by pressing ∪
∪∪
∪+X. This should get you back to the
Psion System Screen, as shown above. If things get really stuck, you may have to
reset the Workabout, as explained in its manual on page 20.
Starting SunData in the Workabout
♦ In the System Screen, use the arrow keys to highlight the SunData application,
and then press
Enter.
SunData will load and then flash up
communicating as it tries to connect to
the probe. Since you haven’t yet
connected the probe, it will let you know
that
Communications failed, and display
this screen (the title screen):
Now, you need to tell SunData to work in Emulator mode.

Menu and then use the ←
