Force 200 Transmitter Output Power OFF

I have a force 200 ePTP slave mode.
suddenly the connection is lost and I find the status in the HOME menu appears Transmitter Output power OFF, not **dBm
so that the wireless cannot be detected with other PTP devices.
the same thing happened when I changed to Access Point mode.
I have tried other countries and the result is the same.
Output power OFF

what should i do so that PTP can reconnect.
thank you

Check monitor:wireless

See if it can see the other radio for that link.

Think alignment, power or major interference.
