STV82x6

Note:

Only standard deviation FM 50K kHz is compatible with other D/K1/K2/K3 standards in Automatic

Standard Recognition Search mode. It has to be deselected when programs with larger FM

deviation are broadcast (reserved only for D/K-Mono or D/K NICAM standard).

FM deviation superior to 350 kHz will degrade strongly NICAM reception due to overlapping of FM

and QPSK IF spectrum in DK-NICAM standard.

L/L’ and DK/K1/K2/K3 standard can be discriminated in Automatic Standard Recognition Search

mode because the same frequency is used for the mono IF carrier.

AUTOSTD is off when all mono standards are disabled.
