When the emergency key is pressed and held for a time determined by the Field

emergency mode.
When emergency mode is triggered, the radio can be configured by the FPP to transmit and

“TxEm”:Channel No.
During TX, the radio will generate an emergency broadcast call on either the currently
selected channel or an FPP nominated channel.
