• StrikeSpeed Wireless (2.4Ghz): Insert the StrikeSpeed+ USB Wireless Receiver (4K Dongle) into an available USB port on your computer. Turn on the mouse. The mouse should automatically connect.

4. Operating Instructions

4.1 DPI Adjustment

The mouse features a PixArt 3395 sensor with up to 26000 DPI. Use the dedicated DPI button (usually located on the top or bottom of the mouse) to cycle through preset DPI levels. You can customize these levels using the FANTECH software.

4.2 Polling Rate

The Helios II Pro S supports high polling rates for responsive gameplay:

• Wired: Up to 8000 Hz
• Wireless (with 4K Dongle): Up to 4000 Hz

Higher polling rates mean more frequent reports to your computer, resulting in smoother and more accurate cursor movement. Ensure your system can handle higher polling rates for optimal performance.

4.3 Programmable Buttons

The mouse has 6 programmable buttons. These can be customized using the FANTECH software to assign macros, keybinds, or other functions to enhance your gaming experience.

4.4 Grip Style

The symmetrical design of the Helios II Pro S accommodates various grip styles, including Palm Grip and Claw Grip, for right-handed users.

5. Maintenance

5.1 Cleaning

To maintain optimal performance and hygiene, regularly clean your mouse. Use a soft, dry cloth to wipe the surface. For stubborn dirt, a slightly damp cloth with mild soap can be used, but ensure no liquid enters the mouse. Avoid harsh chemicals or abrasive materials.

5.2 Battery Care

To prolong battery life, avoid fully discharging the mouse frequently. Charge it when the battery indicator shows low power. Store the mouse in a cool, dry place when not in use for extended periods.

5.3 Mouse Skates and Grips

The mouse comes with extra PTFE mouse skates and anti-slip grips. If your existing skates wear out or you prefer additional grip, you can replace them following the instructions in the FANTECH software or support website.

6. Troubleshooting

• Mouse not responding: Ensure the mouse is charged. Check the connection mode (wireless dongle, Bluetooth, or wired). Try a different USB port or restart your computer.
• Lag or stuttering: Ensure the wireless receiver is close to the mouse and not obstructed. Check for interference from other wireless devices. Lowering the polling rate might help if your system is struggling.
• DPI not changing: Ensure the FANTECH software is installed and running. Check if the DPI button is functioning correctly.
• Bluetooth connection issues: Ensure Bluetooth is enabled on your computer and the mouse is in Bluetooth pairing mode. Remove previous pairings and try reconnecting.
