When a Pocket PC loses it's charge (either from removing the battery or not keeping the unit charged), the Pocket PC is returned to a "factory install" and any software installed, or data will be lost. If this happens, you can reinstall the MyEMR Mobile software from Micrsoft ActiveSync. Once you have established a new Partnership, click Tools > Add/Remove Programs from the ActiveSync Menu Bar. Check the box for MyEMR (Software Motif), then click OK and follow the on-screen and Pocket PC instructions to complete the reinstall. The Pocket PC will then synchronize all the existing data from the desktop to the Pocket PC.
