All sensitivity values refer to
10 dB signal/noise ratio, measured at AM
on external antenna socket, at fully
turned-in variable condenser and
200 pF/400 ohms in series;
C-alignement, tone control at "bass",
band switch at "sharp",
modulation
30% 400 cps.
FM-Sensitivity
= 1,71V for 30dB signal/noise ratio
from the antenna socket.
Limiting Sensitivity
