Selecting “Custom” opens sliders for each band‚ displaying numeric gain values. A “Volume Limit” slider caps output to prevent sudden spikes during calls or music. Firmware updates may add new presets or refine the equalizer’s response curve‚ keeping the headset’s software current for audio.

When using the headset with a computer‚ the OS audio settings can override the headset’s internal volume. In Windows‚ the “Sound” panel lets you set the CS540 as default and adjust master volume.

This is especially useful in environments with varying background noise levels. The CS540 also supports automatic gain control (AGC) which can be enabled or disabled in the app’s “Advanced” settings. When AGC is on‚ the headset automatically adjusts the mic level to maintain consistent voice clarity.

For desktop users‚ the headset’s driver software on Windows or macOS provides a “Microphone Boost” option‚ allowing an additional +10 dB gain. This feature is recommended only when the headset is placed far from the speaker or in very quiet rooms. Users should test the microphone level after each adjustment to avoid clipping or distortion.

Regular maintenance keeps the CS540 headset in peak condition. Begin by removing the ear pads and wiping the earpiece and headband with a soft‚ lint‑free cloth lightly dampened with water or a 70 % isopropyl alcohol solution. Avoid spraying liquids directly onto the headset; instead‚ apply the solution to the cloth. Do not use abrasive cleaners‚ paper towels‚ or harsh chemicals‚ as these can damage the acoustic panels and internal components.

When the headset is not in use‚ store it in the supplied pouch or a dry‚ dust‑free case. Keep it away from extreme temperatures‚ direct sunlight‚ and high humidity‚ which can degrade the battery and plastic parts. If you plan to store the headset for an extended period‚ charge it to 50 % and disconnect the USB cable to prevent deep discharge cycles.
