4.1 Ergonomic Design Benefits
The EKM04 combo is engineered for comfort and to promote a natural posture. The keyboard features a curved and split keyset design, which helps align your wrists and forearms in a more relaxed position. The scooped scissors-switch keys are shaped to fit your fingertips, providing responsive and comfortable typing.

4.2 Hard Palm Rest
The integrated, curved hard palm rest features a leather surface, providing durable and comfortable support for your wrists during extended typing sessions. This wrist rest is non-removable and is designed to be firm rather than soft-cushioned.

4.3 Adjustable Tilt Legs
The ergonomic keyboard is equipped with two adjustable tilt legs on its back. These legs allow you to lift the bottom of the keyboard, helping to maintain a relaxed typing posture, especially when standing. The numeric keypad does not have adjustable tilt legs.

6. Maintenance and Care
6.1 Cleaning
To maintain the performance and appearance of your ProtoArc EKM04 combo:
- Use a soft, dry, lint-free cloth to wipe down the surfaces of the keyboard, numeric keypad, and mouse.
- For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaning solution. Avoid excessive moisture.
- Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the surfaces.
- Use compressed air to remove dust and debris from between the keys.
6.2 Storage
When not in use for extended periods, store the devices in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the devices are powered off to conserve battery life.
7. Troubleshooting
If you encounter issues with your ProtoArc EKM04 combo, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|

Verify the USB receiver is securely plugged into a working USB port on your Windows computer. 3. Confirm the power switches on the keyboard, numeric keypad, and mouse are in the 'ON' position. 4. Remember, this combo is only compatible with Windows systems and does not support Bluetooth. |
| Lag or intermittent connection | Interference from other wireless devices; distance from receiver; low battery. | 1. Move the USB receiver closer to the devices, or try a different USB port. 2. Ensure there are no large metal objects between the devices and the receiver. 3. Charge the devices fully. |
| Mouse cursor erratic or imprecise | Dirty sensor; unsuitable surface; incorrect DPI setting. | 1. Clean the mouse sensor with a soft cloth. 2. Use the mouse on a clean, non-reflective surface or a mouse pad. 3. Adjust the mouse DPI setting using the DPI button on the mouse. |
| Keyboard/Numpad keys not responding | Low battery; connection issue. | 1. Charge the keyboard/numpad. 2. Re-establish the connection by unplugging and re-plugging the USB receiver. |
