It is possible to read the measured SWR value by placing the marker onto the desired frequency (measurement
test point) of the SWR graph.

NDICATION
1. Press the [ F2
](
MARKER
) key to turn the marker
function on; the marker cursor will be displayed.
2. Use the [ F3
]( ) and [
F4
]( ) keys to move the
marker line and select the desired frequency for
which you want to read the previously-measured
SWR.
Advice : Please use an antenna with the SWR below
1.5:1. If the SWR is over 1.5:1, the final protection
circuit activates, and the RF output power may be
reduced.
If the SWR is over 3.0 in the amateur band, there is a
possibility that the coaxial cable or the antenna itself
(antenna system) may have some problem. Please
take the necessary corrective action so as to ensure
optimum, safe performance in your station.
The antenna tuner in the radio can match the SWR
between the transceiver and the antenna; however,
keep in mind that this is not affecting the SWR at the
antenna feedpoint itself. In cases of higher-than-de-
sirable SWR, we recommend corrective action be
taken at the antenna itself.
When you want to clear the measured SWR value at
the marker test point, press the [
F2
](
MARKER
) key.
