Elecom EX-G Trackball Mouse, 2.4GHz USB Wireless, Ergonomic Design, Thumb Control, Smooth Precise Tracking Roller Ball, 6 Programmable Buttons, Tilt Scroll, Computer Mice for Laptop PC, Windows & Mac

Installing the Elecom EX-G Trackball is a straightforward "plug-and-play" process, though there is a specific software if you want to unlock all 6 buttons.

🛠️ Installation Guide (Wireless 2.4GHz)

Insert Battery: Open the battery cover on the underside and insert one AA battery, ensuring the plus (+) and minus (-) ends match the markings.

Retrieve the Receiver: Take the small USB receiver out of its storage slot (usually located on the bottom of the mouse).

Connect to PC: Plug the USB receiver into an available USB port on your Windows or Mac computer.

Power On: Slide the power switch on the bottom to the "L" (Low Energy) or "H" (High Speed) position.

Note: "H" mode is more responsive but consumes battery faster.

Automatic Setup: Your computer should automatically detect the device. The trackball is now ready for basic use!

To Customize Buttons (Optional)

To use the "Tilt Scroll" or the 6 programmable buttons, you need the Elecom Mouse Assistant software:

Visit the official Elecom Global Download page.

Download and install the version for your OS (Windows or macOS).

Restart your computer after installation to enable the custom mappings.

🔍 Frequently Asked Questions

Feature Answer

Windows Compatible? Yes. It works with Windows 11, 10, 8.1, and 7.

Is it Wireless? Yes. It uses a 2.4GHz USB receiver (included).

Left-Handed Use? Check your model. Elecom makes a specific left-handed version (Model: M-XT4DRBK), but the standard EX-G is strictly for right-handed users.

Pro Tip: If the ball feels "sticky" at first, pop it out through the hole in the bottom and wipe it with a microfiber cloth. The bearings sometimes need a quick clean out of the box to reach peak smoothness.

Would you like me to find the download link for the specific driver version for your operating system?

To get the most out of your Elecom EX-G, you’ll want the Elecom Mouse Assistant. The latest version as of early 2026 is Version 6, which offers a more modern interface and better support for Windows 11 and recent macOS versions.

📥 Download Links

For Windows (11/10): Download Mouse Assistant 6

For Mac (macOS 13+): Download Mouse Assistant 6

Note: If you are on an older OS (like macOS 11 or 12), use the Mouse Assistant 5 link instead.

🚀 Setup Steps

Download & Extract: The download comes as a .zip file. Right-click and "Extract All" before running the setup.

Run Installer: Open ELECOM_MA_Setup_6.1.7.exe (or similar) and follow the prompts.

Language Check: If the app opens in Japanese, look for the "Language" or "Utility" menu to switch it to English.

Restart: You must restart your computer after the installation for the custom button assignments to take effect.

💡 Why install this?

Without this software, your computer treats the EX-G as a standard 3-button mouse. With it, you can:

Program the 6th button (often the small button by your ring finger) to "Copy," "Paste," or any custom macro.

Enable Tilt-Scroll: Scroll horizontally in Excel or web browsers by tilting the wheel left or right.

Adjust DPI: Fine-tune the "High" and "Low" speed settings beyond the physical switch.
