PROBLEM
When specifying an ArcPad projection, the datum may default to WGS_84 even if the specified projection is based on a different datum.
This may occur if the default system path is changed or if there is a custom ArcPadPrefs.apx file applied (which may change the default system path).
There should be an apdatums.dbf file in the ArcPad > System folder. This is necessary for the .prj file to use the correct datum.
If the default path for the System Files Path has been changed in ArcPad (Options > Paths), then it may no longer see the apdatums.dbf file. When ArcPad can't see the apdatums.dbf file, the datum will default to WGS_84.
