Step 1: Unbox and Install the G305
Start with the basics:
What’s Inside the Box:
- LIGHTSPEED G305 Wireless Gaming Mouse
- USB wireless receiver (Nano receiver)
- AA battery (pre-installed or included)
- User documentation
Installation Instructions:
- Remove the top shell of the mouse by gently pulling it upward.
- Insert the AA battery into the battery compartment.
- Pull out the USB receiver from its storage slot inside the mouse.
- Plug the USB receiver into an available USB port on your PC or laptop.
- Power on the mouse using the switch on the underside.
Once the receiver is connected, the mouse should automatically be recognized by Windows or macOS.
Step 2: Download and Install Logitech G HUB Software
To unlock the full potential of the G305, install Logitech’s G HUB software.
How to Get G HUB:
- Visit Logitech’s official site.
- Download the latest version of Logitech G HUB for Windows/macOS.
- Run the installer and follow on-screen prompts.
What G HUB Allows You to Do:
- Adjust DPI sensitivity levels
- Reprogram buttons
- Set up macros
- Save profiles to onboard memory
- Check battery status
- Update firmware
Step 3: Set Your DPI for Gaming Precision
DPI (Dots Per Inch) settings determine how fast the cursor moves based on mouse movement. The G305 supports DPI levels from 200 to 12,000.
How to Configure DPI:
- Open G HUB.
- Select your G305 device.
- Click on the DPI icon.
- Adjust DPI levels using the sliders.
- Set up to 5 DPI levels and assign them to the DPI shift button for in-game switching.
Recommended DPI Settings:
- FPS Games: 400 – 800 DPI for better aim accuracy
- RTS/MOBA Games: 1000 – 1600 DPI for fast navigation
- High-Resolution Monitors: 2000+ DPI may be preferred for larger screens
Step 4: Customize the Buttons
The G305 has 6 programmable buttons:
- Left click
- Right click
- Scroll wheel
- DPI switch (behind the scroll)
- Two side buttons (default: forward/backward)
Customize via G HUB:
- Open G HUB and select your G305.
- Navigate to Assignments > Buttons.
- Drag and drop new commands, macros, or keybinds to any button.
This feature is especially useful for:
- Setting reload/melee actions
- Activating abilities in MOBA games
- Using media controls outside gaming
Step 5: Use Onboard Memory for Portability
Once your settings are dialed in, save them to the mouse itself.
How:
- Open G HUB
- Go to Settings > Onboard Memory
- Click “Save to Device” once your profile is complete
This allows the G305 to maintain your custom setup—even if G HUB isn’t installed on another system.
Step 6: Manage Battery Life Efficiently
The G305 boasts an impressive 250 hours of battery life. Still, you can optimize usage:
Tips for Extending Battery Life:
- Switch Off When Not in Use: Use the underside power switch.
- Use Performance Modes in G HUB:
- High Performance (for gaming)
- Endurance Mode (for everyday use)
- Disable RGB (if using other Logitech gear) to conserve battery.
- Check Battery Status in G HUB
Replacing the AA battery with a lithium variant can provide slightly better longevity and lighter weight.
Step 7: Improve Tracking with Proper Surface and Tuning
Though the HERO sensor handles most surfaces well, using a quality mouse pad improves tracking significantly.
Surface Tuning Tips:
- Use a low-friction mouse pad for FPS and precision games.
- Avoid glossy or reflective surfaces which interfere with tracking.
- Keep the sensor lens clean from dust and fingerprints.
For best results, periodically test different DPI settings on your pad to ensure smooth cursor glide and accuracy.
Step 8: Update Firmware for Peak Performance
Logitech occasionally releases firmware updates for the G305 to improve stability or enhance features.
How to Check for Updates:
- Open Logitech G HUB.
- Go to Settings > Device Info
- Click Check for Updates if available.
Keeping firmware current helps avoid bugs, improves wireless performance, and ensures compatibility with new features.
Step 9: Use the Mouse for Productivity and Everyday Use
While built for gaming, the G305 excels in daily tasks as well.
Suggestions:
- Assign Copy, Paste, Undo shortcuts to side buttons
- Set DPI toggle for switching between spreadsheet work and design apps
- Create productivity macros for editing software (Photoshop, Illustrator)
Step 10: Troubleshooting Common Issues
Mouse Not Responding?
- Ensure receiver is connected
- Replace the AA battery
- Test on another USB port
- Try reinstalling G HUB or update drivers
Lag or Intermittent Movement?
- Avoid USB 3.0 ports for the receiver (USB 2.0 preferred)
- Place receiver closer using an extender
