The 2.4 GHz wireless USB-C receiver (also called the dongle) on the Slim Wireless Keyboard and Mouse Combo (models CEX3 and CEX1) is the small USB-C adapter that plugs into your device and connects the keyboard and mouse without Bluetooth. If the receiver is not detecting, re-pair the keyboard first, then the mouse.

Step 1: Pair the keyboard with the receiver

1. Remove the 2.4 GHz USB-C receiver from the storage slot on the back of the keyboard.
2. Insert the receiver into the USB-C port on your device.
3. Wait a few seconds. The CEX3 or CEX1 keyboard should connect automatically.

If the keyboard does not connect automatically:

1. Remove the 2.4 GHz receiver from your device.
2. Press and hold the Fn (function) key, then press the 2.4 GHz receiver icon on the keyboard to enter pairing mode.
3. Reinsert the 2.4 GHz receiver into your device. The keyboard should now pair with the receiver.

Step 2: Pair the mouse with the same receiver

1. Remove the 2.4 GHz receiver from your device. The keyboard stays paired.
2. Turn on the mouse and confirm the pairing LED on the bottom of the mouse is set to the 2.4 GHz receiver icon, then turn the mouse off.
3. Press and hold the right and middle mouse buttons, then turn the mouse on to enter pairing mode.
4. Reinsert the 2.4 GHz receiver into your device. The mouse pairs with the same receiver.

Result: the keyboard and the mouse on the Slim Wireless Keyboard and Mouse Combo are now connected to the same 2.4 GHz USB-C receiver.
