HIGH SWR PROTECTION
If the impedance of the antenna is different than 50 ohms and there is no antenna
tuner connected, the SWR indicator on the display will show a value greater than 1.0.
If the SWR value is 3.0 or more (the SWR indicator on the display will be inverse), the
transceiver will automatically reduce the power output. If the value of SWR is greater
than 3.0, then the output power will decrease more.
A
ATTENTION!
Use a tuned antenna with a wave impedance of 50 ohms, this
is ideal (max output power), or use a matching device (automatic or manual
tuner).
