This section described the 16 types of distinction switch and the contents that are set by these distinction switches.
SW_0 "CLOCK" [Selection of the OSD reference clock]
SW_0&1 "OSD1&OSD2" [Selection of the number
corresponding to the OSD language] Not used
SW_2 "P ON" [Term of the video mute during Power ON]
SW_3 "RFAGC" [Selection of measure when RFAGC = 0]
When "wait 200 ms is used" is set, 200 ms delay is given after
the tuner is switched from external input to tuner and then
selection of stations starts.
SW_4 "MUTE" [Selection of audio mute methods]
MTS=0 Used
MTS=1 Not used
SW_5 "MTS" [Use or not use of MTS]
SW_6 "QSUR" [Use or not use of QSURROUND]
QSUR=0 Used
QSUR=1 Not used
When QSUR = 0 is selected, the remote controller is disabled.
At the same time, the SSURROUND items of the SOUND menu
are not displayed.
Then the blank columns are justified for data display.
[VOL]=0, [QSUR]=0, [BBE]=0, [SBASS]=0, [SWOOFER]=0.
In such cases, the SOUND menu is not displayed.
SW_7 "WEAK" [Use or not use of the sound mute under the
weak electric field]
WEAK=0 Used
WEAK=1 Not used
SW_8 " BBE" [Selection of BBE]
In the case of BBE = 0, pin-35 (BBE) outputs the CMOS "H"
signal.
When BBE = 0 is selected, the remote controller is disabled.
At the same time, the BBE items of the SOUND menu are not
displayed.
Then the blank columns are justified for data display.
[VOL]=0, [QSUR]=0, [BBE]=0, [SBASS]=0, [SWOOFER]=0.
In such cases, the SOUND menu is not displayed.
BBE=0 Used
BBE=1 Not used
PON=0 MUTE=2.7sec
PON=1 MUTE=5.4sec
When MTS is used, only the remote controller is selected.
When MTS = 0 is selected, the remote controller is disabled and
discrimination of audio multiplexing is not implemented.
