Is it possible to install the configuration tool on a
PDA not listed on the release note compatibility
list?
No.
I drained the PDA batteries and lost my saved
configuration files. Is it possible to restore these
files from a saved location?
One of two methods can work:
— Uploading the configuration from a properly
configured T7350. This recovers all but the given
configuration name and corresponding holiday
names.
— Regular use of the HotSync®function to back up
data to a PC saves T7350 configurations. In the
case of a battery failure, the Palm™ Desktop
application automatically restores the saved
configurations at the next HotSync event from the
StatDbFile-HIRW.PDB file.
