Connectivity

Choose your connection mode

The keyboard can connect in 2.4G mode using the USB receiver, or in Bluetooth mode. For Bluetooth, the first connection requires entering pairing mode manually.

2.4G = fast plug-and-play wireless setup

Bluetooth = pair once from your computer settings

2.4

2.4G (USB dongle)

1

Take out the USB receiver
The 2.4G dongle is stored inside the keyboard for travel.
2

Plug the dongle into your computer
Use a direct USB port if possible.
3

Press the 2.4G button on the keyboard
The 2.4G indicator should light up, confirming that 2.4G mode is selected.

The USB receiver is stored inside the keyboard. Take it out, plug it in, and you’re ready.

Usually the simplest option: once the dongle is plugged in and 2.4G mode is selected, the keyboard should be ready to use.

Bluetooth pairing

1

Press the Bluetooth button once
The Bluetooth mode LED indicator light will turn on.
2

Press and hold the Bluetooth button for 3 seconds
The Bluetooth LED will flash rapidly. This means the keyboard is now in pairing mode.
3

Open Bluetooth settings on your PC or laptop
Click Add Bluetooth or other devices.
4

Select the keyboard in the device list
The keyboard name will appear as IOP582/583/584.
5

Confirm the connection on your computer
If your computer shows a pairing window or confirmation message, simply validate it to finish connecting the keyboard.

LED on = Bluetooth mode selected.
LED flashing fast = pairing mode active.

Important: for the first Bluetooth connection, pressing the Bluetooth button once is not enough. You must hold it for 3 seconds until the Bluetooth light starts flashing quickly.

Good to know

✓

The keyboard remembers the last mode used

After the first setup, you usually won’t need to pair it again unless you remove the device from your computer.

If Bluetooth doesn’t show up

Make sure the Bluetooth light is flashing rapidly. If it is only solid, pairing mode is not active yet.

↺

If it was paired before but won’t reconnect

Remove the device from your Bluetooth settings, then repeat the Bluetooth pairing steps from the beginning.
