Redragon K708AK-RGB-PRO: driver, software, Bluetooth, 2.4 GHz, display, and RGB lighting

Last Updated on 18.09.2026 by DriverNew

Redragon K708AK-RGB-PRO is a 75% wireless mechanical keyboard with 81 keys, USB-C, 2.4 GHz, and Bluetooth connectivity, a built-in color display, and RGB lighting. A separate proprietary Redragon driver is not required for normal operation. After connection, Windows automatically uses the standard HID keyboard driver.

For advanced configuration, Redragon provides separate software for K708AK-RGB-PRO. It is designed for remapping supported keys, creating macros, working with profiles, and additional RGB settings.

Important: after installation, the official K708AK-RGB-PRO program may appear under the internal name KS82 PRO MAX. This does not mean that software for another keyboard was downloaded. The verified official K708AK-RGB-PRO installer does in fact use this internal designation.

Does Redragon K708AK-RGB-PRO need a driver?

A separate Redragon system driver is not required for basic operation.

Windows automatically installs the necessary HID components after connection:

  • via USB-C;
  • through the included 2.4 GHz USB receiver;
  • via Bluetooth.

If the keyboard types and the main keys work, you do not need to look for an additional driver.

The proprietary Redragon program is a configuration utility and does not replace the standard Windows HID driver.

Official K708AK-RGB-PRO software

It is recommended to download the program from the official Redragon download center:

Redragon software

For K708AK-RGB-PRO, Redragon provides a separate installer:

Redragon K708AK-RGB-PRO.exe

Verification showed that this installer is currently identical to the official K708MC-RGB-PRO package. However, for K708AK it is recommended to download the software through the page for this specific model, because Redragon may change the software packages in the future.

Do not install software for another K708 version just because the name is similar. For K708AK-RGB-PRO, use the download that the official website provides specifically for this model.

Why the program is called KS82 PRO MAX

The following designation is used inside the verified official K708AK-RGB-PRO installer:

KS82 PRO MAX

Therefore, after installation, the name of the program window, shortcut, or executable file may differ from the marketing name Redragon K708AK-RGB-PRO.

Do not uninstall the program just because it is called KS82 PRO MAX if it was installed from a file downloaded from the official K708AK-RGB-PRO page.

Installer digital signature

The verified K708AK-RGB-PRO installer has an Authenticode digital signature.

The end-entity signer certificate lists:

Shenzhen Evision Semiconductor Technology Co., Ltd

Therefore, the usual instructions for bypassing a SmartScreen warning for an unsigned file are not required for this installer.

If the file downloaded for K708AK-RGB-PRO unexpectedly shows an unknown publisher or Windows reports a problem with the digital signature, do not run it immediately. Download the program again through the official Redragon page and check the file once more.

How to install K708AK-RGB-PRO software

  1. First connect the keyboard and make sure it works normally without the proprietary software.
  2. Download the program specifically for K708AK-RGB-PRO.
  3. For the initial installation, it is recommended to use a wired USB-C connection.
  4. Close Redragon programs for other keyboards.
  5. Run Redragon K708AK-RGB-PRO.exe.
  6. Confirm the Windows prompt to allow changes if it appears.
  7. Complete the installation.
  8. Launch the program.
  9. Do not be surprised if the interface uses the name KS82 PRO MAX.
  10. Check whether the keyboard is detected.

If you only need normal text input, built-in RGB effects, and wireless connectivity, you do not need to install the program.

Wired USB-C connection

Wired mode is convenient for the initial check, charging, and diagnosing wireless connectivity.

  1. Move the 2.4G / OFF / BT switch to OFF.
  2. Connect the USB-C cable to the keyboard.
  3. Connect the other end of the cable directly to a USB port on the computer.
  4. Wait a few seconds.
  5. Open a text editor and test text input.
The OFF position is used for wired mode when the USB-C cable is connected. This does not mean that the keyboard cannot be used over a wired connection.

If K708AK-RGB-PRO works normally over USB, the standard Windows HID driver is installed correctly.

Connecting via 2.4 GHz

The included USB receiver is used for 2.4 GHz mode.

  1. Move the keyboard switch to 2.4G.
  2. Connect the included USB receiver directly to a USB port on the computer.
  3. Wait a few seconds.
  4. Test the keyboard.

If pairing has been saved, the connection is usually established automatically.

Re-pairing via 2.4 GHz

If the keyboard works over USB or Bluetooth but no longer connects to the included receiver:

  1. Make sure the keyboard has sufficient charge.
  2. Move the switch to 2.4G.
  3. Disconnect the USB receiver from the computer.
  4. Press and hold FN + 4 for about 3 seconds.
  5. Wait for the indicator to flash rapidly.
  6. Connect the included USB receiver to the computer.
  7. Place the keyboard near the receiver.
  8. Wait for pairing to complete.
Use the included USB receiver. Receivers from different Redragon keyboards may look identical, but this does not mean they are compatible.

Connecting K708AK-RGB-PRO via Bluetooth

The keyboard supports three Bluetooth profiles.

Key combination Profile Indicator color
FN + 1 Bluetooth 1 Blue
FN + 2 Bluetooth 2 Red
FN + 3 Bluetooth 3 Green

A short press is used to switch between previously saved Bluetooth profiles. For new pairing, hold the selected key combination for about 3 seconds.

In the list of Bluetooth devices, the keyboard may appear as:

  • BT5.2_1;
  • BT5.2_2;
  • BT5.2_3.

Removing the Bluetooth pairing does not remove the standard Windows HID driver and does not affect the 2.4 GHz connection.

Controlling RGB lighting without the program

The main RGB functions can be controlled directly from the keyboard.

Key combination Function
FN + right Shift Switch between built-in RGB effects.
FN + ↑ Increase brightness.
FN + ↓ Decrease brightness.
FN + → Increase the speed of the dynamic effect.
FN + ← Decrease the speed of the dynamic effect.
FN + Enter Change the color in supported modes.

The keyboard supports several built-in RGB effects, and brightness and speed can be adjusted through several levels.

If the lighting does not work as expected, first switch through several built-in effects and adjust the brightness. There is no need to reinstall the HID driver just because of RGB settings.

Custom lighting without the program

K708AK-RGB-PRO lets you create your own lighting layout directly from the keyboard.

Use:

FN + Backspace

  1. Press FN + Backspace to enter custom mode.
  2. Use the combination again to start recording.
  3. After entering configuration mode, the Caps Lock indicator starts flashing.
  4. Select the required key and press it repeatedly to set its color.
  5. Repeat the configuration for the other keys.
  6. Press FN + Backspace to save the result.

For more advanced RGB configuration, you can use the proprietary program.

Built-in 1.14-inch color display

K708AK-RGB-PRO is equipped with a built-in color display and a multifunction knob.

To use the menu:

  1. Press the multifunction knob to open the menu.
  2. Rotate the knob to move between the available items.
  3. Press the knob to confirm the selected function.

If no action is taken for several seconds, the screen returns to normal mode.

The built-in menu allows you to change supported hardware settings without launching the program in Windows.

If the display does not work

If the keyboard types but the screen does not display information:

  1. Connect K708AK-RGB-PRO via USB-C.
  2. Check the multifunction knob.
  3. Try opening the built-in menu by pressing the knob.
  4. Disconnect the keyboard for a few seconds and connect it again.
  5. Perform a factory reset with FN + ESC.
  6. Test the device before launching the proprietary program.

If the keyboard works but the display remains completely inactive after a reset and reconnection, the cause may be hardware-related. Reinstalling the standard HID driver usually does not restore a faulty display.

Switching between Windows and macOS modes

For Windows, use:

FN + W

For macOS:

FN + A

The operating system mode may also be available through the built-in display menu.

On K708AK-RGB-PRO, FN + W is used for Windows mode. Do not apply K684 key combinations to this model, where FN + W performs a different function.

If the Win, Alt, or other system keys begin working unusually in Windows, first restore Windows mode with FN + W.

Locking the Windows key

To lock the Windows key, use:

FN + Win

Pressing the combination again restores normal operation of the key.

Multimedia functions

FN + F7 Previous track.
FN + F8 Play / pause.
FN + F9 Next track.
FN + F10 Mute or unmute sound.
FN + F11 Decrease volume.
FN + F12 Increase volume.

How to check the battery level

To display the battery level, use:

FN + INS

Hold the combination to make the keyboard display the battery level. After you release the keys, the device returns to the current RGB mode.

When the battery level is low, connect the keyboard with a USB-C cable.

Resetting K708AK-RGB-PRO to factory settings

If the keyboard works incorrectly after changing RGB, profiles, the operating system mode, or other settings, perform a hardware reset.

Press and hold:

FN + ESC

Hold the combination for about 3 seconds.

After the reset, first test the keyboard without launching the proprietary program.

A factory reset may delete custom settings, including created macros and lighting profiles.

What the KS82 PRO MAX program is used for

Despite the internal KS82 PRO MAX name, in this case it refers to the program that the official Redragon website provides for K708AK-RGB-PRO.

It is intended for supported functions including:

  • key remapping;
  • macro creation;
  • profile management;
  • advanced RGB lighting configuration.

This program is not required to connect the keyboard via USB-C, 2.4 GHz, or Bluetooth.

Creating macros

  1. Connect K708AK-RGB-PRO to the computer.
  2. Launch the proprietary program. In the interface, it may be called KS82 PRO MAX.
  3. Open the macro management section.
  4. Create a new macro.
  5. Record the required key sequence.
  6. If necessary, configure the available delays.
  7. Save the macro.
  8. Assign it to a supported key.
  9. Apply the changes.
  10. Test the result.
When using macros in games, follow the rules of the specific game. Some types of automation may be prohibited.

If the program does not detect K708AK-RGB-PRO

If the keyboard works normally but the proprietary program does not detect the device:

  1. Make sure the installer was downloaded specifically from the K708AK-RGB-PRO page.
  2. Do not uninstall the program just because of the internal name KS82 PRO MAX.
  3. Move the keyboard switch to OFF.
  4. Connect the keyboard directly to the computer with a USB-C cable.
  5. Do not use a USB hub or docking station.
  6. Try another USB port.
  7. Close Redragon programs for other devices.
  8. Close KS82 PRO MAX and launch the program again.
  9. Restart Windows if necessary.
If the keyboard types normally, the standard Windows HID driver is already working. If the program does not detect K708AK-RGB-PRO, do not remove the system HID driver as your first troubleshooting step.

If software for another K708 version is installed

Before installing the correct software, it is recommended to remove the incompatible program.

Windows 11

  1. Open Settings → Apps → Installed apps.
  2. Find the Redragon program for another K708 version.
  3. Open the menu next to its name.
  4. Select Uninstall.
  5. Restart Windows.
  6. If necessary, perform an FN + ESC reset.
  7. Test K708AK-RGB-PRO without the program.
  8. Install the official package specifically for K708AK-RGB-PRO.

Windows 10

  1. Open Settings → Apps → Apps & features.
  2. Find the incorrect Redragon program.
  3. Select it and click Uninstall.
  4. Restart Windows.
  5. Test the keyboard without the proprietary software.
  6. Then install the K708AK-RGB-PRO program.

Removing the proprietary program does not remove the standard Windows HID driver.

If Bluetooth and 2.4 GHz do not work

First test the keyboard in wired mode.

  1. Move the switch to OFF.
  2. Connect the USB-C cable.
  3. Test text input.

If the keyboard works over USB:

  1. charge the device;
  2. check the position of the mode switch;
  3. repeat 2.4 GHz pairing using FN + 4;
  4. remove the old Bluetooth pairing and create it again;
  5. try another USB port for the receiver.

If wired mode works, the problem is usually not related to the basic Windows HID driver.

If the 2.4 GHz connection drops intermittently

  1. Check the keyboard’s charge level.
  2. Connect the receiver directly to the computer.
  3. Do not use a USB hub for testing.
  4. Try another USB port.
  5. Move the keyboard closer to the receiver.
  6. Move the receiver away from sources of strong radio interference.
  7. If necessary, repeat pairing using FN + 4.

If Bluetooth disconnects intermittently

  1. Check the battery level.
  2. Make sure the correct Bluetooth profile is selected.
  3. Move the keyboard closer to the computer.
  4. Remove the old pairing and add the device again.
  5. Test the keyboard with another computer or another Bluetooth device.

If K708AK-RGB-PRO works reliably over USB and 2.4 GHz but Bluetooth disconnects only on one computer, also check that computer’s Bluetooth adapter and its driver.

If one key does not work

K708AK-RGB-PRO supports replaceable mechanical switches. Therefore, if one key fails, you can test the switch itself.

  1. Turn off the keyboard and disconnect the USB-C cable.
  2. Remove the keycap from the problem key.
  3. Carefully remove the switch with a suitable switch puller.
  4. Check the metal contacts.
  5. Install a known-good compatible 3-pin or 5-pin switch.
  6. Turn on the keyboard and test it again.

If the problem moves with the switch, the switch itself is most likely faulty.

If the same key position still does not work with a known-good switch, there may be a problem with the hot-swap socket, PCB, or another hardware component.

If a key registers twice

If one press sometimes produces two identical characters:

  1. Test the problem key in a normal text editor.
  2. Close the proprietary program and repeat the test.
  3. Test the keyboard in wired USB mode.
  4. If the problem persists, turn off the keyboard.
  5. Replace the suspected switch with a known-good one.
  6. Repeat the test.

If the double input moves with the switch, the switch is the cause. If it remains at the same key position, there may be a fault in the hot-swap socket or PCB.

Before replacing a mechanical switch, turn off the keyboard and disconnect the USB-C cable. Install the switch carefully to avoid bending its contacts.

If Windows does not detect K708AK-RGB-PRO at all

Use wired mode for diagnosis.

  1. Move the switch to OFF.
  2. Connect the USB-C cable directly to the computer.
  3. Try another USB port.
  4. Do not use a USB hub.
  5. If possible, try another known-good USB-C cable that supports data transfer.
  6. Restart Windows.
  7. Test the keyboard on another computer.

If K708AK-RGB-PRO works on another computer, you can have Windows redetect the HID device.

Redetecting the keyboard in Windows

  1. Connect K708AK-RGB-PRO via USB.
  2. Right-click the Start button and select Device Manager.
  3. Expand Keyboards.
  4. If several HID keyboards are displayed, do not uninstall all of them.
  5. Disconnect K708AK-RGB-PRO and identify which entry disappears.
  6. Connect the keyboard again and make sure the corresponding entry reappears.
  7. Right-click the device you have positively identified.
  8. Select Uninstall device.
  9. Disconnect the keyboard for a few seconds.
  10. Connect it again.

Windows will automatically reinstall the standard HID driver.

If K708AK-RGB-PRO is not detected over USB even on another computer, installing software for another Redragon model usually will not help. In this case, check the USB-C cable, connector, and the keyboard itself.
