Notes:
*1 - Input signal level must be within the limits, that the signal on output makes minus 3 dB of output
signal at UI=31.6 мВ.
*2 - Input signal level is set equal to 0 mkV and then is raised up to the moment when "STEREO"
mode indicator switches on.
*3 - Input signal level is set equal to 1 mV and then is reduced to the moment when "STEREO"
mode indicator switches off.
*4 - Frequency deviation at which voltage constant on output 10 (AGC/AFC2) is equal to the voltage
on output 21 (REG), of path central frequency (10.7 MHz).
*5 - Sensitivity means that signal level on AM IF input at which voltage on channel outputs is set
equal to 15.5 mV (active value)
