1. Introduction
Thank you for choosing the ATK U2 V2 Ultimate Wireless Mouse. This high-performance gaming mouse is designed for competitive gamers, featuring a lightweight design, multiple connection modes, a flagship sensor, and ultra-low latency for precise and responsive control. This manual will guide you through the setup, operation, and maintenance of your new mouse.
2. Setup
2.1 Package Contents
The ATK U2 V2 Ultimate Master Version typically includes:
- ATK U2 V2 Ultimate Wireless Mouse
- 8K Nano Receiver
- Braided Data Cable
- User Guide
- Warranty Certificate
- Safety Specification Guide
- Additional Gray Competitive Foot Stickers (pre-installed gray cotton foot)
- Receiver Extension Adapter
2.2 Charging the Mouse
Before first use, it is recommended to fully charge the mouse. Connect the braided data cable to the mouse's charging port and a USB power source (e.g., computer USB port, USB wall adapter). The LED indicator on the mouse will show charging status.
2.3 Connection Modes
The ATK U2 V2 Ultimate Wireless Mouse supports three connection modes:
- 2.4G Wireless Mode: Insert the 8K Nano Receiver into an available USB port on your computer. The mouse should automatically connect. This mode offers the lowest latency and highest polling rate.
- Bluetooth Mode: Turn on Bluetooth on your computer. Put the mouse into Bluetooth pairing mode (refer to the mouse's specific button combination for pairing, usually a button on the bottom). Select the mouse from your computer's Bluetooth device list to pair.
- Wired Mode: Connect the braided data cable directly from the mouse to your computer's USB port. The mouse will function as a wired mouse and charge simultaneously.
2.4 Software Installation (ATK HUB 3.0)
For full customization and advanced features, download and install the ATK HUB 3.0 software from the official ATK website. This software allows you to:
- Adjust DPI settings
- Configure polling rate
- Remap buttons
- Create macros
- Adjust Lift-Off Distance (LOD)
- Monitor battery status
3. Operating Instructions
3.1 DPI Adjustment
The mouse features a dedicated DPI button (usually located on the top or bottom of the mouse) to cycle through preset DPI levels. You can customize these levels and add more steps using the ATK HUB 3.0 software. The PAW3950Ultra sensor offers a DPI adjustment range of 10-30000, overclockable up to 42000.
3.2 Polling Rate
The ATK U2 V2 Ultimate Mouse supports up to 8KHz polling rate in both wired and wireless modes (with the 8K Nano Receiver). A higher polling rate means more frequent data transmission to your computer, resulting in smoother and more responsive cursor movement. You can adjust the polling rate via the ATK HUB 3.0 software.
3.3 Lift-Off Distance (LOD)
The LOD can be adjusted between 0.7mm, 1.0mm, and 2.0mm with 0.1mm precision across 11 adjustable levels using the ATK HUB 3.0 software. This allows you to fine-tune how far the mouse can be lifted before tracking stops, preventing unwanted cursor movement during quick lifts.
3.4 Ergonomics and Design
The mouse features an ergonomic, waist-supported design optimized for e-sports, providing a comfortable experience with a secure clasp and grasp. Its lightweight construction (45g for Ultimate Master Version, 39g for Mini Master Edition) reduces fatigue during extended use.
4. Maintenance
4.1 Cleaning
The mouse features a Nano Ice-Feel Coating which is sweat-resistant, stain-proof, and easy to clean. To clean your mouse:
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the coating and internal components.
- Do not spray cleaners directly onto the mouse.
- Ensure the mouse is powered off and disconnected before cleaning.
4.2 Foot Stickers
The mouse comes with pre-installed foot stickers (gray cotton foot for Ultimate Master Version). If these wear out, replacement foot stickers are available and can be installed by carefully peeling off the old ones and applying new ones, ensuring proper alignment.
5. Troubleshooting
If you encounter issues with your ATK U2 V2 Ultimate Wireless Mouse, please refer to the following common solutions:
- Mouse not responding: Ensure the mouse is powered on and fully charged. Check the connection mode (2.4G receiver, Bluetooth, or wired cable) and ensure it's properly established. Try a different USB port for the receiver or cable.
- Lag or stuttering cursor: Ensure the 2.4G receiver is close to the mouse and not obstructed. Avoid using the mouse near other wireless devices that might cause interference. Update mouse drivers and firmware via ATK HUB 3.0. Lower the polling rate if necessary, though 8KHz is generally stable.
- DPI/Sensitivity issues: Use the dedicated DPI button to cycle through settings. If custom settings are not applying, ensure the ATK HUB 3.0 software is running and settings are saved.
- Battery not charging: Ensure the charging cable is securely connected to both the mouse and a working USB power source. Try a different cable or USB port.
- ATK HUB 3.0 software not detecting mouse: Ensure the mouse is connected to the computer (preferably wired or 2.4G wireless) and powered on. Reinstall the ATK HUB 3.0 software.
