Audible Overload
If Audible Overload is set to On, an audible alarm is sounded whenever an input is
overloaded.
Command: AOVL (?) {i}
Screen Saver
Turns the Screen Saver On or Off. Using the Screen Saver extends the life of the video
display and prevents screen ‘burn’.
When the Screen Saver is On and the Screen Saver Delay passes without a key press,
knob turn or interface command, the screen will be blanked and random patterns are
displayed. Press any key to return the screen to normal.
Command: \SAVR (?) {i}
Screen Saver Delay
Set the Screen Saver Delay in minutes [1..59].
When the Screen Saver is on and the Screen Saver Delay passes without a key press,
knob turn or interface command, the screen will be blanked and random patterns
displayed. Press any key to return the screen to normal.
Command: SDLY (?) {i}
Frequency Format
Select the Frequency Format [Exact Bin, Rounded].
Exact Bin displays frequencies exactly. This can make the frequency display have many
more digits than required to distinguish adjacent frequency bins. However, this format is
useful when determining the exact frequency of a bin.
Rounded shortens the frequency displays to show only those digits which are required to
distinguish adjacent frequency bins. This simplifies and shortens the frequency displays
but does not show the exact frequency of a bin.
For example, for a 400 line FFT on 100.0 kHz base with a span of 97.66 Hz, the first
frequency bin is shown as 244.140625 mHz (Exact Bin) or 244.1 mHz (Rounded). The
second bin is 488.28125 mHz (Exact Bin) and 488.3 mHz (Rounded).
Command: FFMT (?) {i}
Node Info Prompt
Turns the node information prompt when saving files on or off.
