When performing a tuning ac�on via a long press of the Tune bu�on, the
tuner will go through its complete matching procedure and then return to
receive mode a�er comple�on. (this may take several seconds)
When your antenna is physically very close (e.g. a ver�cal mobile antenna),
strong radio frequency interference may be caused to the radio or electronic
equipment nearby. If this happens try to locate the antenna further away.

A long press of the [POW] bu�on enables the standing-wave scanning
func�on. It will scan the SWR of the antenna currently connected.
Press the bu�on below the BW label on the screen momentarily to switch
the frequency step of the scan.
At the bo�om of the screen, the frequency of the lowest SWR point of the
scanned standing wave is indicated. This is where the antenna is “resonant”.
Press the bu�on below the FAST/ SLOW label on the screen momentarily to
select the scanning speed.
Press the bu�on below the QUIT label on the screen to exit the
standing-wave scanner.

The SWR scanner is for quick reference only and is not meant to replace a
dedicated antenna analyzer. It is a very useful tool for trimming and
adjus�ng an antenna when opera�ng portable or for spo�ng a faulty
antenna.
