Troubleshooting
Psion Workabout
There is no SunData Icon in the system screen.
• From the Psion system screen, select Menu, Apps, Install, Enter, Tab, and select
Sundata.app in the \SUN\ subdirectory. If this file does not exist, it must be
copied from the SunScan program disk - refer to the appendix: File Transfer
between Workabout and PC.
The system fails to recognise a Flashcard in the A: or B: drives.
• Make sure the SSD drawer is firmly closed.
The Workabout gives continuous “low battery” warnings, even after fully recharging
the battery pack.
• Remove and then replace the battery pack when it is fully charged. This will reset
the “low battery” warnings.
Problems running the SunData application.
SunData fails to run, with exit code 80.
• The supporting file Sys$8087.ldd is not in the \SUN\ subdirectory. Copy it there
from the SunScan program disk - refer to the installation notes.
SunData reports “serial port in use”.
• Exit the program, and make sure the Remote Link is off. Press Menu, Spec,
Remote Link, Enter,
from the system screen.
SunData fails with “insufficient memory” or “insufficient system resources” message.
• Close any other applications that are running. Delete any unnecessary data files
stored on the Internal drive. From the system screen, select
Menu, Info, Memory
Info, Enter
. If the amount of System memory is shown as more than 80k, reboot
the Workabout (
∪
∪∪
∪+Ctrl+Del) and reinstall the SunData Icon. As a last resort, cold
boot the Workabout (∪

∪+Shift+Ctrl+Del). You will then have to reinstall the
SunData programs from the SunScan program disk - see the complete installation
instructions.
While running SunData
SunData reports “SunScan probe not connected”.
• Check the cable connections. Check the condition of the batteries in the SunScan
probe.
SunData recognises the SunScan probe, but fails to take readings.
• Exit the SunData program, and run it again. If “BFS” is selected as the external
sensor in
Menu, Settings, SunScan Probe, Enter, make sure a Beam Fraction
sensor is connected and is exposed to some light.
On running SunData, all the system settings are scrambled.
• The Default.cfg may be corrupted. Exit SunData and delete the file Default.cfg
in the \SUN\ subdirectory.
“Out of memory” reported on drive A:.
• Replace the Flashcard with an empty formatted one and start a new data file.
Transfer the data on the full Flashcard to a PC and reformat it.
