SCOPE OPERATION
Spectrum scope screen
The spectrum scope enables you to display the
activity on the selected band, as well as the relative
strengths of various signals.
The transceiver has two spectrum scope modes, the
Center mode and the Fixed mode.
You can also turn the Waterfall display ON or OFF.
In addition, you can select the Mini scope to display it
in a smaller size on the screen.

• About RX Marker
In the Fixed mode, the RX Marker displays the
operating frequency within a specified frequency
range. So, the transceiver always displays the RX
marker in the scope screen.
In the Center mode, the operating frequency stays on
the Center of the screen. Thus, the transceiver does
not display the RX Marker.
L
When the Hold function is ON, the RX Marker is displayed
to indicate the operating frequency’s position.
: The RX marker displays the re-
ceive frequency.
: The TX marker displays the trans-
mit frequency.
