5.1 Keyboard Usage

The keyboard functions as a standard full-size keyboard. Utilize the F-key shortcuts for quick access to media controls and other system functions. These functions are typically indicated by blue legends on the F-keys (e.g., volume control, play/pause, brightness). Press the Fn key in combination with the desired F-key to activate these functions if they are not primary.

5.2 Mouse Usage

The mouse provides standard left-click, right-click, and scroll wheel functionality. To adjust the mouse cursor speed (DPI), press the DPI button located on the underside of the mouse. Each press cycles through available DPI settings.

5.3 Compatibility

The Nulea KM74 combo is compatible with personal computers and laptops running Windows and Mac operating systems.

6. Charging

Both the Nulea KM74 keyboard and mouse are equipped with built-in rechargeable batteries. When the battery level is low, a low power indicator light may illuminate on the respective device.

Connect the provided USB-C charging cable to the USB-C port on the keyboard (located on the back edge).
Connect the provided USB-C charging cable to the USB-C port on the mouse (located on the front underside).
Plug the other end of the USB-C cable into a standard USB power source (e.g., computer USB port, USB wall adapter).

7. Maintenance

Cleaning: Use a soft, dry, lint-free cloth to clean the surfaces of the keyboard and mouse. For stubborn dirt, a slightly damp cloth can be used, ensuring no moisture enters the device openings.
Storage: When not in use, especially during travel, store the 2.4G USB receiver in its designated slot within the mouse to prevent loss.
Environment: Avoid exposing the devices to extreme temperatures, direct sunlight, high humidity, or corrosive substances.
Handling: Do not drop, disassemble, or attempt to repair the devices yourself. This may void the warranty and cause damage.

8. Troubleshooting

Problem	Possible Solution
Keyboard/Mouse not connecting or unresponsive.	Ensure the 2.4G USB receiver is securely plugged into a working USB port on your computer. Verify that both the keyboard and mouse are switched to the "ON" position. Check the battery levels of both devices and charge them if necessary. Try plugging the USB receiver into a different USB port on your computer. Restart your computer.
Lag or intermittent connection.	Ensure the devices are within the effective wireless range (approximately 33 feet or 10 meters) of the USB receiver. Minimize potential interference from other 2.4G wireless devices (e.g., Wi-Fi routers, cordless phones) by moving them further away. Avoid placing the receiver near large metal objects.
Mouse cursor erratic or not moving smoothly.	Clean the optical sensor on the underside of the mouse. Ensure you are using the mouse on a suitable surface (non-reflective, non-transparent). Adjust the DPI setting using the DPI button on the mouse.
Keyboard keys not responding.	Ensure the keyboard is fully charged. Check for any physical obstructions under the keys. If specific keys are consistently unresponsive, contact customer support.
