8. Safety and Maintenance

Safety Precautions

To ensure maximum safety when using the Razer BlackWidow V4 X, follow these guidelines:

• If you encounter any issues using the device correctly and troubleshooting steps do not resolve them, disconnect the device and contact Razer support or visit support.razer.com for assistance.
• Do not disassemble the device, as this will void the warranty. Do not attempt to operate it under abnormal circumstances.
• Keep the device away from liquids or humidity. The device should operate within a temperature range of 0°C to 40°C. If the temperature exceeds this range, disconnect or turn off the device to allow it to stabilize.

Ergonomics

Studies show that repetitive movements, improper posture, and poor habits can lead to discomfort and injuries. Razer offers the following recommendations for injury prevention and maximum comfort:

1. Position your monitor and keyboard directly in front of you, with the mouse to the side. Keep your elbows at your sides, not too far out. The keyboard should be within easy reach.
2. Adjust your chair and desk height so that the keyboard and mouse are at or below elbow height.
3. Keep your feet flat on the floor, maintain an upright posture, and relax your shoulders.
4. When typing, relax your wrists and keep them straight. Avoid bending, extending, or twisting your hands for prolonged periods during repetitive tasks.
5. Do not rest your wrists on hard surfaces for extended periods.
6. Use the included wrist rest to support your wrists while using the keyboard.
7. Customize your keyboard keys to adapt to your work style and minimize forced repetitive movements while typing.
8. Avoid sitting in the same posture all day. Stand up, walk, and do exercises to stretch your arms, shoulders, neck, and legs.

If you experience any physical discomfort (e.g., pain, numbness, or tingling in your hands, wrists, elbows, shoulders, neck, or back) while using the keyboard, consult a medical professional immediately.

Usage and Maintenance

The Razer BlackWidow V4 X requires minimal maintenance to stay in optimal condition. To prevent dirt buildup, it is recommended to disconnect the device from your computer once a month and clean all its components using a soft cloth or cotton swab.
