Operating Instructions
Ergonomic Design and Comfort
The Nulea RT07B features a split keyboard layout and a comprehensive palm rest designed to promote a natural typing posture. This reduces forearm muscle twisting and wrist strain, contributing to long-term comfort.

Adjustable Tilt Legs
The keyboard includes adjustable tilt legs on both the front and back. These can be used to customize the typing angle for optimal wrist comfort. Raising the front legs can create a negative tilt, which some users find more ergonomic by allowing wrists to remain in a more neutral position.

Scissor-Switch Keys
