4. Installation and Setup
Follow these steps to install your new surmen MOA Profile Keycaps:
- Prepare Your Keyboard: Disconnect your keyboard from your computer. If your keyboard has backlighting, turn it off.
- Remove Existing Keycaps: Use a keycap puller (not included) to carefully remove your current keycaps. Grip the keycap firmly and pull straight up to avoid damaging the switch stem.
- Organize New Keycaps: Refer to the included layout diagram (if applicable) or the image below to identify the correct placement for each keycap. The set includes standard and supplementary keys for various layouts.
- Install New Keycaps: Align each new keycap with the corresponding switch stem. Press down gently but firmly until the keycap is seated securely. Ensure the keycap is level and does not wobble.
- Test Functionality: Once all keycaps are installed, reconnect your keyboard and test each key to ensure proper function.

5. Usage
The MOA profile is designed for a comfortable and unique typing experience. Its uniform height across all rows, combined with the rounded, sculpted tops, aims to reduce finger fatigue and provide a distinct feel compared to traditional profiles like Cherry or OEM.
The thick PBT material contributes to a satisfying typing sound and feel, often described as more 'thocky' than thinner ABS keycaps. The dye-sublimated legends ensure long-lasting clarity and resistance to wear.

6. Maintenance
To ensure the longevity and appearance of your surmen keycaps, follow these maintenance guidelines:
- Regular Cleaning: Dust and debris can accumulate between keycaps. Use a soft brush or compressed air to remove loose particles regularly.
- Deep Cleaning: For a more thorough clean, remove the keycaps using a keycap puller. Wash them in lukewarm water with a mild soap. Avoid harsh chemicals or abrasive materials, as these can damage the PBT plastic and dye-sublimated legends. Rinse thoroughly and allow them to air dry completely before re-installing.
- Avoid Excessive Force: When removing or installing keycaps, use gentle, even pressure. Excessive force can damage the keycap stems or the keyboard switches.
7. Troubleshooting
If you encounter any issues with your keycaps, consider the following:
- Keycaps Not Fitting: Ensure your keyboard uses cross-shaped switch stems (e.g., Cherry MX compatible). Some non-standard layouts or stabilizers may not be compatible with the provided keycap sizes. Double-check the layout diagram for correct keycap placement.
- Wobbly Keycaps: Ensure the keycap is fully pressed down onto the switch stem. If a keycap still wobbles excessively, inspect the switch stem for damage or manufacturing inconsistencies.
- Missing or Defective Keycaps: While quality control is maintained, occasional manufacturing defects can occur. If you receive a set with missing or visibly defective keycaps, please contact customer support for assistance.
- Legends Not Lighting Up (Shine-Through): These keycaps are PBT dye-sublimated, and while the material itself is thick, the legends are not designed for shine-through backlighting. The primary illumination will be around the keycaps, not through the characters themselves.
