You can use the Primary Responder mode configuration setting to manually enable the TX40 device to
be in an AT&T FirstNet-compliant mode (Primary Responder mode). When a device is in Primary
Responder mode, certain firmware features are disabled. See
operation and Primary Responder
Disable Primary Responder Mode
If you enable Primary Responder mode and then disable it, the device's configuration is erased and
the device will reboot. You will then need to reconfigure the device to the desired configuration.
Differences between standard firmware operation and Primary
Responder mode

device. When enabled, the device acts as a Primary Responder (PR) device with a security hardened,

security requirements.
