Your SIMpad operating system can be upgraded.
This replaces the entire operating system as well as installed programs.
All existing data will be deleted! Before executing such an update you
should therefore back up all your important data on a PC (see page 26).
During an update, SIMpad should be connected to AC power or the bat-
tery must be fully charged.
Now perform a hardreset. To do this, hold down the button on the
right above the control key and then press the reset button on the base of
the device using the stylus.
Set up an Internet connection (page 13).
Close the Internet connection and all applications.
Tap Start “ Programs “ Tools “ Software Update. The dialog box Soft-
ware Update is displayed:
Tap in the system area on the taskbar. Then tap the tab Memory and
move the control to the far right (see page 78). Confirm by tapping OK.
To start the update, tap Start.
Follow the instructions on the screen. A progress bar appears. The update
lasts approx. 1 hour with an ISDN dial-up connection, or approx. 10 min-
utes with an ADSL connection (e.g. with HomeRF Gateway). A dialog win-
dow then appears in which you must confirm the start of the Flash writing
procedure.
After the update of your device software, execute a factory reset. To do
this: Simultaneously press
(right button above the control key) and
(button below the control key). Then use the stylus to briefly press
the RESET button on the base of the device. Hold down both buttons for
a further two seconds.
Once this is completed, the SIMpad factory settings are restored. You
must perform the startup operations again (see page 9).
