So recently I acquired a CS7000, I tore out the M7300 brick and used a separate CH-721 control head in a remote mount configuration. So far everything seems to work fine, except when I turn the volume knob all the way off on the control head, the power cycles but the radio never turns off. It stays on all the time. I currently have a CAN terminator on the brick, but not on the control head. Could the lack of a CAN terminator on the CH-721 be the issue?
