Determines whether the unit is armed for antenna alignment and whether it emits audible installation tones indicating signal state and strength (armWithTones or armWithoutTones), or whether configuration changes can be made without arming (changeConfigWithoutArming), typically once a link is already established. It is read-write; note that while armed, the unit has reduced link performance and functionality, so an installer would disarm it (or use changeConfigWithoutArming) once alignment is complete.
