3. Connecting Your Keyboard
The IROK ZN84 supports three connection modes: Bluetooth (BT5.0), 2.4GHz Wireless, and USB-C Wired.
USB-C Wired Connection:
- Locate the USB-C port on the keyboard.
- Connect the provided USB-C cable to the keyboard and the other end to an available USB port on your computer.
- The keyboard will be automatically recognized and ready for use. Note: RGB backlight is fully functional in wired mode.
2.4GHz Wireless Connection:
- Ensure AAA batteries are installed.
- Locate the 2.4G wireless receiver (dongle) usually found in a slot on the keyboard or packaging.
- Plug the 2.4G receiver into an available USB port on your computer.
- Switch the mode selector switch on the keyboard to the '2.4G' position.
- The keyboard should connect automatically.
Bluetooth (BT5.0) Connection:
- Ensure AAA batteries are installed.
- Switch the mode selector switch on the keyboard to the 'BT' position.
- On your computer or device, enable Bluetooth and search for new devices.
- Select 'IROK ZN84' (or similar name) from the list of available devices to pair.
- The keyboard can connect to up to 3 Bluetooth devices simultaneously. Use specific key combinations (refer to keyboard legends or quick guide) to switch between paired devices.
Important Note: The RGB backlight only functions when the keyboard is connected via wired (USB-C) mode. It is not available in Bluetooth or 2.4GHz wireless modes to conserve battery life.
Operating Instructions
1. System Switching (Mac/Windows)
The keyboard supports one-click conversion between Mac and Windows operating systems. Refer to the keyboard's key legends for the specific key combination (e.g., Fn + A/S) to switch modes.
