Spectrum scope screen

D Marker

The Marker displays the operating frequency for both
the Main and Sub bands in the SPECTRUM SCOPE
screen.
M: The Main band marker
• Marks the Main band frequency.
S: The Sub band marker
• Marks the Sub band frequency.
T: The TX marker
• Marks the transmit frequency.
• About Main and Sub Marker
In the Fixed or Scroll mode, the Main and Sub band
Marker displays the operating frequency within a
specified frequency range. So, the transceiver always
displays the Main or Sub band marker in the Scope
screen.
In the Center mode, the operating frequency stays in
the center of the screen. Thus, the transceiver does
not display either the Main band marker on the Main
scope, or the Sub band marker on the Sub scope.
L When the Hold function is ON, the RX Marker is displayed
to indicate the operating frequency's location.

displayed with another function displays, such as
