attenuator hold mode, a change in frequency setting has forced the ALC
beyond its range.

The firmware has changed the power setting to a value other than the
requested value due to the fact that, while in attenuator hold mode, the
user has requested a power setting that is below the ALC range for the
attenuator setting. The power has been set to the lower limit.
