How do I disable the ATU, using the Maestro?

Mike-N1VE Member ✭✭

I am currently using the Flex-6400 connected to an amplifier with a built-in tuner. I want to disable the Flex ATU. I am using the Maestro.

    Just found the answer to my question by poking knobs. Press the MIC/SPEED knob to bring up menu. Touch ATU MEM to disable the memory.

    I do not have a Maestro (yet). However, pressing and holding the ATU button on the front panel of my 6600M places the ATU in bypass mode. Does this work on the Maestro?

    Yes, but only temporarily. As soon as you change frequency to where it must retune, it will retune. Got to completely disable the ATU when using an amplifier with a built-in tuner.
