Frequently asked questions
Can all users talk at the same time
PMR is half duplex so one user transmits at a time. This keeps messages clear and controlled in noisy conditions.
Can the channel be muted or silenced
Yes. You can adjust volume, change channels and mute the microphone when needed.
How does this differ from Bluetooth mesh headsets
This model uses an integrated PMR radio. It does not rely on smartphones or apps and uses the standard J11 Nexus interface for accessories.
Is the battery field replaceable
Yes. The removable battery can be swapped in seconds to a charged spare.
Is it suitable for music playback
No. The device is designed for communication and hearing protection, not for high fidelity audio.
