Cursor
Red vertical line that indicates position during the channel or frequency
tuning.
When a digital signal is detected, there is a triple cursor that shows the
frequency for the signal locked and two vertical lines that shows the
bandwidth of the digital carrier.
In the case of a GENERIC signal, the bandwidth shown is the one selected
by the user on the "Signal Parameters" menu when pressing the
key.
To change frequency/channel use the joystick (left, right) in FR mode
(tuning by frequency) or CH mode (tuning by channel).

Δ L : Difference of power level between the marker and the main
