Maintenance
Proper care will extend the lifespan and maintain the performance of your Oversteel Phosphorus headset.
- Cleaning: Use a soft, dry cloth to wipe down the headset's surfaces. For ear cushions, a slightly damp cloth can be used, but ensure they are completely dry before use. Avoid harsh chemicals or abrasive materials.
- Storage: Store the headset in a cool, dry place away from direct sunlight and extreme temperatures. Avoid placing heavy objects on the headset.
- Cable Care: Do not pull on the cable excessively or bend it sharply. Store the cable neatly to prevent tangling and damage.
- Durability: The headset features a resistant aluminum frame, contributing to its durability. However, avoid dropping or subjecting the headset to strong impacts.
Troubleshooting
If you encounter issues with your Oversteel Phosphorus headset, refer to the following common solutions:
- No Sound or Low Volume:
- Ensure the USB cable is securely plugged into the device.
- Check the on-cable volume control and increase the volume.
- Verify that the headset is selected as the default audio output device in your device's sound settings.
- Test the headset on another device to rule out a device-specific issue.
- Microphone Not Working:
- Ensure the microphone mute button on the cable control is disengaged (microphone is not muted).
- Check that the headset is selected as the default recording device in your device's sound settings.
- Confirm that the application you are using (e.g., game, communication software) is configured to use the headset microphone.
- Test the microphone on another device or application.
- RGB Lighting Not Working:
- Ensure the headset is properly connected via USB.
- Press the RGB lighting button on the cable control unit to activate it.
- Note that the RGB lighting typically cycles automatically and may not offer manual color selection.
- Software Issues: If you experience problems with the dedicated software, ensure you have downloaded the correct version from the official Oversteel website. If the website or software is unavailable, the headset will still function with its basic features and on-cable controls.
- Connectivity Clarification: Please note that despite some descriptions, the Oversteel Phosphorus headset primarily uses a USB connection for audio and microphone functions. While a 3.5mm jack might be mentioned in some contexts, the main interface is USB, and direct 3.5mm connectivity for all features may not be supported without an adapter.
