These steps are based on the official manual for the Q3 Ultra model and general usage of Keychron\u2019s multi-device Bluetooth functionality.\n\n---\n\n## \ud83d\udd27 What You\u2019ll Need to Know First\n\n- The Q3 Ultra supports Bluetooth 5.3 and allows pairing up to **three Bluetooth devices**. ([keychron.com](https://www.keychron.com/products/keychron-q3-ultra-8k-wireless-custom-mechanical-keyboard?utm_source=openai))  \n- There\u2019s a small physical **mode switch** on the keyboard that lets you toggle between *Cable (wired)*, *2.4 GHz wireless*, and *Bluetooth* modes. ([manual.do](https://www.manual.do/keychron/q3-ultra-8k/manual?utm_source=openai))  \n- Make sure you\u2019ve charged your keyboard so battery isn\u2019t an issue during setup. ([tomsguide.com](https://www.tomsguide.com/computing/keyboards/keychron-q3-ultra-8k-review?utm_source=openai))  \n\n---\n\n## 1. How to Enter Pairing Mode\n\n1. Locate the mode switch (usually on the back or side of the keyboard). Slide it to **BT** (Bluetooth). ([manual.do](https://www.manual.do/keychron/q3-ultra-8k/manual?utm_source=openai))  \n2. Press and **hold `Fn + 1` for about 4 seconds** until the Bluetooth indicator starts flashing rapidly. This means it's commanding pairing mode for **Bluetooth channel 1**. ([manual.do](https://www.manual.do/keychron/q3-ultra-8k/manual?utm_source=openai))  \n3. On the device you want to connect (phone, tablet, computer), open Bluetooth settings and look for `Keychron Q3 Ultra 8K`. Once it shows up, select it to pair. When it\u2019s connected successfully, the indicator light will stop flashing. ([manual.do](https://www.manual.do/keychron/q3-ultra-8k/manual?utm_source=openai))  \n\n---\n\n## 2. Pairing Additional Devices (Up to Three)\n\nTo add more devices:\n\n- After pairing the first device with **`Fn + 1`**, put the keyboard into Bluetooth mode again.\n- Hold **`Fn + 2`** for ~4 seconds to pair a second device.\n- Similarly, hold **`Fn + 3`** to pair a third device. Each corresponds to a separate Bluetooth \u201cslot.\u201d ([keychron.com](https://www.keychron.com/products/keychron-q3-ultra-8k-wireless-custom-mechanical-keyboard?utm_source=openai))  \n\n---\n\n## 3. Switching Between Paired Devices\n\nOnce you\u2019ve got 2\u20133 devices paired:\n\n- Use **`Fn + 1`**, **`Fn + 2`**, or **`Fn + 3`** to instantly switch between devices. You only need a **short press**\u2014no need to hold it down. ([manuals.plus](https://manuals.plus/keychron/q3-pro-qmk-via-wireless-custom-mechanical-keyboard-manual?utm_source=openai))  \n\n---\n\n## 4. Reconnecting to the Last Device\n\nIf the keyboard is already paired but not actively connected:\n\n- Switch the keyboard to Bluetooth mode (`BT`).\n- It should automatically try to reconnect to the **last paired device**, with the indicator flashing briefly. ([manuals.plus](https://manuals.plus/keychron/q3-pro-qmk-via-wireless-custom-mechanical-keyboard-manual?utm_source=openai))  \n- If nothing happens, press *any key* to wake up scanning/connection mode. ([manuals.plus](https://manuals.plus/keychron/q3-pro-qmk-via-wireless-custom-mechanical-keyboard-manual?utm_source=openai))  \n\n---\n\n## 5. Troubleshooting Common Issues\n\n- If a device **won\u2019t appear** in Bluetooth settings, make sure the keyboard is in pairing mode with the correct `Fn + [1/2/3]` held for long enough. ([manual.do](https://www.manual.do/keychron/q3-ultra-8k/manual?utm_source=openai))  \n- If trying to pair anew fails repeatedly, try a full reset: **hold `Fn + 1 + 2 + 3` together for ~5 seconds**. This clears Bluetooth pair memory. ([teamplush.by](https://teamplush.by/en/product/keychron-q3/?utm_source=openai))  \n- Make sure your OS\u2019s Bluetooth is turned on and functional; sometimes a driver or hardware issue on the computer/phone side can block pairing.\n\n---\n\nIf you tell me which device you\u2019re using (Windows, macOS, Android, iOS, etc.), I can give you more tailored instructions. Want me to walk you through that?"
