Electronic Bias Settings (EBS) is one of significant feature of the power amplifier. It allows to set low

plate current after pressing the PTT regardless of whether you have CW or SSB mode, until RF signal

is no present at the input. At the moment when RF signal comes to the input of PA, bias will

automatically change to its working value.
