To re-install the GEA 110, perform the removal procedures in reverse. If the unit is mounted to the

tray, tighten the mounting screw by hand until the unit is secure.
If the GEA 110 was replaced, the sensor configurations must be loaded to the new unit using the following
procedure:
1. Power on the GI 275 that is directly interfaced to the GEA 110 into Configuration mode.

icon should appear in the bottom-left of the display once the GI 275 has recognized the device. If
the icon doesn't appear after 1 minute, remove the drive and re-insert it.
