Select the tab below that matches the type of keyboard you have. Follow the steps on how to connect your keyboard to your computer.

  1. Locate the wireless USB receiver that came with your keyboard.
    NOTE:

    When buying a keyboard or mouse with a computer:

    • Look in every compartment of the box that the device came in. The wireless USB receiver is small and can be overlooked. The receiver has an informational tag that is attached to help you locate the receiver. See Figure 1 to see the size and shape of the receiver.

    When buying a keyboard or mouse separately from a computer:

    • The wireless USB receiver is under the keyboard when buying a keyboard or keyboard-mouse combination and under the mouse when purchased separately. The receiver has an informational tag that is attached to help you locate the receiver. See Figure 2 for the typical location, size, and shape of the receiver.

    Figure 1: Wireless Receive    		   Keyboard_Packaging_Receiver
    Figure 2: Wireless Receiver Location in Packaging

    When you cannot locate your wireless receiver after you have unpacked the devices, some mice and keyboards have a place to store the wireless receiver. Look under the mouse buttons where the batteries are or in the battery compartment on the keyboard.

  2. Ensure that the keyboard is turned on.
    NOTE: The power switch can be in one of several locations. See the Dell article 133505, Manuals, and Documentation for your Dell Product for information about how to locate, and download, or view the manual for your Dell device to locate the power switch.
  3. Insert the wireless USB receiver, as shown in Figure 3.

    NOTES:
    • The receiver only goes in one way. When the connector does not seem to fit, adjust the angle, or flip it over.
    • When using the receiver that came with the keyboard, no driver or configuration is needed for the keyboard to work.
    • Your receiver and keyboard may have a connect button; if so, press the connect button on the receiver and on the bottom of the keyboard. See the example in Figure 4.
