5. Push the Isothermal PCA and the Main PCA together so that the Isothermal PCA
pins go deeper into the Main PCA sockets. This holds the IR Lens in place and
allows the Main PCA to be reinstalled into the top case.
Reinstalling the Main PCA
1. While holding the IR Lens to the Main PCA, turn the Main PCA over so that the
components are facing up.
2. Align the screw holes in the Main PCA with those in the top case.
3. Align the backlight pins with the Main PCA sockets.
4. Align the Main PCA holes with the backlight posts.
5. Gently push the Main PCA down into the top case, making sure that the IR Lens goes
into the groove on the LCD-end of the top case. If it does not fit together easily,
check to make sure that everything is properly lined up and try again.
6. Reinsert and tighten the two pca screws.
To complete the thermometer reassembly, screw the bottom case to the top case, reinstall
the batteries and screw the battery compartment shut.
