4 Set the attenuation state to Auto (default):
Press {More} > {More} > {Attenuation Auto} > {More}
5 Press {Y Scale} > {Auto Scale} > {Return} to set the Y scale.
6 Set the AM depth limit and turn on the limit function:
Press {More} > {Limits} > {AM Depth UP} > [76] > {%} > {AM
Depth Low} > [70] > {%} > {Limits on}
The red value in the result indicates the demodulated AM
depth exceeds the limits set as above.
