4.4.6 Updating driving program

The driving programs for electric wheelchairs are
continually updated and improved by Invacare®. For this
reason, you should check whether the version number
is still up to date each time a wheelchair comes in for
repairs, and also during regular inspections.
If a newer version is available, the driving program must be
updated. The procedure for updating the driving program
is described in the user manual of the Wizard software.
The electronic system is supplied with a standard
drive program. If the driving program has been
customised, you have to perform this customisation
again, after installing the new driving program.
