Operating the Mouse
Button Functions
The Razer DeathAdder features five independently programmable Hyperesponse™ buttons. By default, these buttons perform standard mouse functions:
- Left Click: Primary action.
- Right Click: Secondary action/context menu.
- Scroll Wheel Click: Middle click, often used for opening links in new tabs or auto-scrolling.
- Scroll Up/Down: Vertical scrolling.
- Side Buttons (Forward/Back): Navigation in web browsers or other applications.
You can customize these button assignments using the Razer Synapse software to suit your gaming or productivity needs.
On-The-Fly Sensitivity™ Adjustment
The Razer DeathAdder allows for real-time sensitivity adjustments. By default, this feature is often mapped to specific button combinations or can be assigned to a dedicated button via Razer Synapse. This enables you to quickly switch between different DPI settings for various in-game scenarios, such as precise aiming or rapid movement.

Maintenance
Cleaning Your Mouse
To ensure optimal performance and longevity of your Razer DeathAdder, regular cleaning is recommended:
- Exterior: Use a soft, lint-free cloth lightly dampened with water or a mild cleaning solution. Avoid harsh chemicals or abrasive materials.
- Sensor Lens: Gently clean the infrared sensor lens on the underside of the mouse with a cotton swab or a soft, dry cloth. Do not use liquids directly on the sensor.
- Cable: Wipe the braided fiber cable with a dry cloth to remove dust.
Always ensure the mouse is disconnected from your computer before cleaning.
Troubleshooting
Mouse Not Responding
- Check USB Connection: Ensure the USB cable is securely plugged into a working USB port on your computer. Try a different USB port.
- Restart Computer: A simple restart can often resolve connectivity issues.
- Test on Another Computer: If possible, test the mouse on another computer to determine if the issue is with the mouse or your system.
- Reinstall Drivers: Uninstall the Razer Synapse software and any related drivers, then reinstall them from the official Razer website.
Tracking Issues / Jittery Cursor
- Clean Sensor: Dust or debris on the infrared sensor can cause tracking problems. Refer to the "Maintenance" section for cleaning instructions.
- Mouse Surface: Ensure you are using the mouse on a clean, uniform, and non-reflective surface. Highly reflective or uneven surfaces can interfere with the sensor.
