5.2 Volume Control
The M30 headset features independent volume controls for ambient sound amplification.
- Increase Volume: Press the '+' button to increase the amplification level of ambient sounds.
- Decrease Volume: Press the '-' button to decrease the amplification level of ambient sounds.
5.3 Noise Reduction Functionality
The EARMOR M30 is an electronic hearing protector designed to reduce harmful impulse noises (e.g., gunshots) to a safe level while amplifying low-level sounds (e.g., conversation, range commands). This allows for situational awareness without compromising hearing safety.
The electronic circuitry instantly suppresses loud noises above a certain decibel threshold, protecting your hearing. When the noise subsides, the amplification returns to its set level.
6. Maintenance
6.1 Cleaning
- Wipe the exterior of the headset with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure no moisture enters the electronic components.
- Periodically inspect the ear cushions for wear and tear. Replace them if they become damaged to maintain proper seal and protection.
6.2 Storage
Store the headset in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
6.3 Battery Replacement
