d) Move cursor to one adjustment item, then press keys “VOL-” and “VOL+” can adjust it;
e) Press key “MENU” can exit adjustment menu of one page to its superior factory menu;
f) Press key “EXIT” can exit factory menu at any time;
g) Press key “OK” can enter into inferior factory menu;
h) Factory menu item “ADC
Calibrate” is used to correct ADC of VGA and Component channel;
i) Factory menu item “W/B ADJUST” is used to adjust white balance;
j) Factory menu item “POWER MODE” is used to set power-on mode, “Standby” means the set will be in standby state after power-on; “MEM” means the set will be in the state before the last power-off; “ForceOn” means the set will be working automatically after power-on, this mode is also used for factory-machine-aging; default setting should be “Standby” mode unless specified by customer requirement;
k) Factory menu item “ISP MODE” is used to upgrade unit software from VGA port when the item is set as “ON” and the set is connected to ISP adjustment equipment; DDC function of VGA port will be recovered when the item is set as “OFF”; the value of the item can not be kept in the memory, that is to say the item is reset as “OFF” after power-on again;
l) Factory menu item “RESET ALL” is used to reset factory menu data and user menu data; after execute the item, the set will be started up again and the startup guided picture will be displayed;
m) Factory menu item “FACTORY CHANNEL PRESET” is used to preset factory programs data; it is necessary to connect to central signal source for DTV searching programs. Now digital frequency of central signal CH28(529.5 MHz) and CH33(564.5 MHz) are distributed to Australia programs. Primary preset programs would not be modified along with the changing of central signals, so please select item DTV in menu Channel to manual search digital programs, the process will spend about 15s;
n) Factory menu item “CUSTOM CHANNEL PRESET” : first delete all DTV/ATV programs for factory adjustment, then preset ATV channel data according to customer order requirements; please execute the item to clear out all programs for factory adjustment before leaving factory;
o) Factory menu item “MST Debug” :default setting “OFF” is used for engineering models whose RS232 functions can measure up to design specifications; setting “ON” is convenient for debugging by developing tools; the value of the item can not be kept in the memory, that is to say the item is reset as “OFF” after power-on again;
p) Factory menu item “BACKLIGHT” is used to adjust backlight brightness, adjust the item and test voltage of X801-12# (PWM) to measure up to the maximum PWM voltage in panel specification;
q) Factory menu item “SSC ADJUST” is used to adjust expended functions of frequency content, the software having been preset according to model need not be adjusted again;
r) Factory menu item “AUDIO Curve” is used to adjust audio curve; without special customer requirements, the software having been preset according to model need not be adjusted again;
If the software has been upgraded or EEPROM has data already, please execute item “RESET ALL” before adjustment for the first time.

adjust
B gun: adjust B gun value downwards , then coordinates of X,Y
will rise;
adjust B gun value upwards , then coordinates of X,Y will descent;
adjust R gun will effect the coordinate of X , and effect the value of Lv a little:
adjust R gun value upwards , then coordinate of X will rise;
adjust R gun value downwards , then coordinate of X will descent;
