It supports up to 5 devices — 1 via 2.4GHz, 3 via Bluetooth, and 1 via wired mode (auto-priority).
What's included in the box?

Troubleshooting
My keyboard isn't pairing via Bluetooth. What should I do?
Make sure you're long-pressing the device key to trigger first-time pairing mode, and confirm your device's Bluetooth is turned on and in discoverable/scanning mode before pairing again.
The keyboard isn't responding via the 2.4GHz receiver. What should I check?
Confirm the nano receiver is fully inserted into a working USB port, and press the matching device key on the keyboard to activate that connection.
My Fn shortcuts or multimedia keys aren't working correctly on my device.
Check that the OS switch key is set to match the device you're currently using (Windows / macOS / Android / iOS). Shortcuts are remapped per OS, so an incorrect OS setting can cause mismatched behavior
