RAMA WORKS® M65-B
Shim Installation Guide
Some of the M65-B units suffered from an issue of the plate not aligning correctly with the housing, which resulted in certain keycaps interfering with the blocker, or the side of the top housing and in some cases, the spacebar.
Below is a guide for the installation of shims which will push the plate aside, enough so that the keycaps should no longer be rubbing against the keyboard housing.
Start by flipping the top housing over. Install two of the shims in the locations shown below. This should be the left side of the housing (when the keyboard is upright), which will result in the subassembly being pushed to the right.
Next, install six shims on the bottom of the housing (when the keyboard is upright). This will result in the subassembly being pushed upwards.
