Operating Instructions
Microphone Muting
The microphone boom features an integrated On/Off switch for quick muting:
- To Activate Microphone: Rotate the microphone boom down towards your mouth. The microphone will automatically activate.
- To Mute Microphone: Rotate the microphone boom upwards, away from your mouth. The microphone will automatically mute.
Audio Monitoring
Listen to incoming audio through the single earcup. The enclosed earphone design provides high ambient-noise attenuation, helping to isolate the audio from external distractions.
Comfort and Prolonged Use
The headset is designed for durable and comfortable wear during prolonged use. Ensure the fit is snug but not overly tight to prevent discomfort over long periods.
Maintenance
Proper maintenance ensures the longevity and performance of your headset.
- Cleaning: Use a soft, dry cloth to wipe down the headset and cable. For the ear-pad, a slightly damp cloth with mild soap can be used, but ensure it is completely dry before use. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the headset in a clean, dry place away from extreme temperatures and direct sunlight. Avoid tangling the cable.
- Cable Care: Do not pull on the cable to disconnect the headset. Always grasp the XLR connector firmly. Avoid sharp bends or kinks in the cable.
- Microphone Boom: Handle the microphone boom gently. While it is designed for 300-degree rotation, avoid forcing it beyond its natural range of motion.
