TV SERVICE MENU
In TUNER SYSTEM it is possible to set only relevant tuner systems to ON (only multi
standard TV’s). This is done to reduce the tuning time.
AFC ON/OFF is used in connection with adjustments but it may also be useful in
other situations.
The AFC is set to ON when the TV has been turned off by means of the mains switch.
CN SOUND (ON) / OFF
Used to compensate for different sound modulation levels from TV transmitters in
China.
Normally the frequency deviation is 00 kHz, but in China some TV transmitters
are transmitting “Wide Sound” which has a frequency deviation of 30 kHz. This
results in bad sound - distortion - because of the higher modulation level. To
compensate for this CN SOUND must be set to ON.
The function is only working in combination with the tuner system D/K.
If the function is set to ON with other tuner systems it will not influence the sound.
