Service Supplement:
D9400/D9410 Series Digital-Control Color Monitor
There are five switches on the control panel with Key Function:
① OSD/EXIT OSD—Call the Main-Menu OSD
② FUN - /FUN + When the Main-Menu is displayed, you can select each function using these keys.
③ KEY - /KEY + When the Sub-Menu is displayed, you can change the amplitude of the selected
function of the screen using these keys.
BRIGHTNESS ADJUSTMENT:
OSD (On screen display menu) CONTROLS & ADJUSTMENTS:
OSD FUN - FUN + KEY - KEY +
1) Press the “OSD” key—the Main-Menu OSD will come up as pictured above.
2) Search “BRIGHTNESS” sub-menu using “FUN -” or “FUN +” key on the Main-Menu OSD.
3) The “BRIGHTNESS” OSD color changes from blue to red.
4) Adjust Brightness as much as you want using “KEY -” or “KEY +”.
5) After finishing the Brightness adjust, press the “OSD” key. The “OSD” will disappear. The new Brightness value will be
saved automatically.
6) If you want to adjust other functions (sub-menu), search the function using “FUN -” or “FUN +”, and then repeat the
same procedures of steps 2–5.
7) Press the “OSD” key again to finish adjustments and the OSD will disappear. If no action is taken in the OSD, the menu
will disappear by itself.
Note: When the “RECALL” key is pressed, all user’s adjustment values are changed to the factory values.
