Introduction
Thank you for choosing the Delux M900PRO Wireless Gaming Mouse. This manual provides essential information for setting up, operating, and maintaining your new gaming mouse.

Package Contents
Please ensure all items are present in your package:
- Delux M900PRO Wireless Gaming Mouse
- 1.6m Braided Cable (USB-C to USB-A)
- Grip Tape
- PTFE Mouse Feet (replacement set)
- Magnetic Charging Dock
- 2.4G Nano Receiver (8KHz compatible)

Setup Instructions
- Unboxing and Preparation: Carefully remove the mouse and all accessories from the packaging.
- Remove Protective Film: Before first use, remember to peel off the protective film from the bottom PTFE mouse feet. This ensures optimal glide.
- Connect Receiver: Insert the 2.4G Nano Receiver into an available USB port on your computer.
- Power On Mouse: Locate the power switch on the bottom of the mouse and slide it to the 'ON' position.
- Pairing (if necessary): In 2.4G mode, if the mouse does not connect automatically, long-press the bottom DPI button for 3 seconds. The DPI indicator will flash green (for 1 minute, indicating code pairing time). Ensure the receiver is plugged in during this time. Once successfully paired, the mouse will function normally.
- Driver Installation: For full customization and advanced features, download and install the exclusive Delux driver software from the official website: www.deluxworld.com/en-service.html. The driver is compatible with Windows 8/10/11.

Operating Instructions
Charging the Mouse
The M900PRO supports two charging methods: wired and wireless magnetic charging.
- Magnetic Charging: Place the mouse onto the Magnetic Charging Dock, aligning it with the magnetic position. The dock features RGB lighting effects. A full charge takes approximately 2 hours and provides up to 65 hours of battery life.
- Wired Charging: Connect the mouse directly to your computer using the provided 1.6m braided USB-C cable. The mouse can be used while charging.

DPI Adjustment
The mouse features a dedicated DPI adjust button. Use this button to cycle through preset DPI levels. Fine-tune DPI settings from 50-26000 via the Delux Exclusive Driver software.
Polling Rate
The M900PRO supports polling rates from 125Hz up to 8000Hz. The 8KHz polling rate, achieved with the 8K nano receiver, reduces latency to 0.125ms for high-level gaming. Adjust polling rate settings via the Delux Exclusive Driver software.

Full-function Customization
Utilize the Delux Exclusive Driver software (Windows 8/10/11 only) to:
- Re-assign all buttons.
- Program macros.
- Customize DPI settings (50-26000 DPI).
- Adjust Lift-Off Distance (LOD) to 1mm/2mm.
- Set Debounce time (2-50ms adjustable).
- Configure Polling Rate (up to 8000Hz).
- Enable Ripple control and Linear calibration.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the mouse. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the mouse.
- PTFE Feet: The mouse is equipped with low-friction, wear-resistant PTFE feet for smooth operation. If the glide performance degrades, replace them with the spare set provided.
- Anti-slip Grip: The anti-slip grip helps prevent sweat and dirt buildup, enhancing control. Keep this area clean for best performance.
- Receiver Storage: The mouse features anti-loss and dustproof receiver storage on its underside. Store the 2.4G receiver here when not in use or when traveling.

Troubleshooting
- Mouse not responding: Ensure the mouse is powered on and the 2.4G receiver is securely plugged into a USB port. Try re-pairing the receiver as described in the Setup Instructions. Check battery level.
- 8KHz Polling Rate not working: Verify that you are using the 8K Nano Receiver. Ensure the polling rate is set to 8000Hz in the Delux Exclusive Driver software. Some games or system configurations might not fully support 8KHz, potentially causing issues.
- Lag or stuttering: Ensure the 2.4G receiver is placed close to the mouse and away from potential interference sources (e.g., other wireless devices, large metal objects). Lowering the polling rate to 4000Hz or 1000Hz might resolve stability issues in certain games or systems.
- Custom settings not applying: Make sure the Delux Exclusive Driver software is installed and running. Apply changes within the software and ensure the mouse is connected.
- Mouse not charging: Check that the charging cable is securely connected to both the mouse/dock and the power source. For magnetic charging, ensure the mouse is correctly aligned on the dock.
