Can the channel be muted or silenced?
Yes. Volume and monitoring can be adjusted, and the user can change channels or mute the microphone when needed.
How does this differ from Bluetooth mesh systems?
This model uses a built-in PMR radio. It does not rely on smartphones or apps, and connections use standard industrial J11/Nexus ports.
Is the battery field-replaceable?
Yes. The removable battery can be swapped in seconds to a spare unit, minimizing downtime.
Is it suitable for listening to music?
No. This device is designed for communication and hearing protection, not audio playback.
