Fastening module steel guide screws

If a module is not securely in contact with the UHK, fastening its screws should solve the issue.

Slightly loosen the eight highlighted screws below. When fixing a right-sided module, the relevant eight screws of the right module and right keyboard half apply.

Now, join the module and the UHK. While pushing the UHK and the module at the pogo pins (the 5 metal contact pins) toward each other, tighten the 8 screws.

Your module should be securely in contact with your UHK. It's normal if you can see a small gap between your module and your UHK.

If you still encounter issues after the above fix, to isolate whether module connectivity is the issue, it's worth pushing your module to your UHK and simultaneously applying a sticky tape on the bottom to keep the module and UHK together as closely as possible.
