It is important to setup the sync to run on a computer that will have Atlas open on a regular basis, but this computer does not need to be one linked to the Imaging Software (ex: the Millennium computer). Most offices opt to have their Front Desk PC run the sync program.
Click Setup > Initial Setup > Rooms
NOTE: in the above example, there is only 1 'Room' available - most offices will have a list of options here and should have one designated 'Front Desk' (or Main PC, etc). To determine which PC you are using, click on the Set Computer Location button.
Check off IMPORT on the room you want to trigger the sync program.
IMPORTANT: Only check off one room for IMPORT - Atlas must be running on this PC for the IMPORT function to work!
