Instruções de operação
1. Ligar/desligar e controle de volume
Each ear cup typically has independent power and volume controls.
- Press and hold the power button (often integrated with volume controls) to turn the unit on or off.
- Use the '+' and '-' buttons to adjust the volume of the environmental listening feature.
- The left and right sides operate independently, allowing for individual volume adjustment if needed.
2. Environmental Listening (Talk-Through)
The Comtac earmuffs feature an environmental listening function, also known as "talk-through," which allows you to hear your surroundings and engage in face-to-face conversations while still being protected from loud noises.
- Microphones on the ear cups pick up ambient sounds, which are then reproduced inside the earmuffs.
- When a loud noise occurs, the system instantly reduces the volume to a safe level, then restores normal listening once the hazardous noise subsides. This compression technology ensures continuous situational awareness without abrupt sound cut-offs.
3. Two-Way Communications
For models equipped with communication capabilities (e.g., single or dual comm variants), the headset allows for clear, intelligible two-way audio communications via radios and intercoms. The Hearing Defender variant can be upgraded with communication downleads and boom mics (sold separately) to enable this functionality.
4. Advanced Audio Settings
The Comtac earmuffs offer advanced audio adjustments for specific situations:
- Aumento de ganho: Para amplify quiet sounds or maintain audibility when wearing inner earplugs, hold the volume up button for approximately ten seconds after turning on the headset. This boosts the gain significantly.
- Ajuste de resposta de frequência: By holding the volume down button, you can adjust the frequency response of the headset. This allows you to tailor the sound profile, por exemploample, by boosting lows if highs are too sharp, enhancing comfort during prolonged exposure to constant noise.
