3.Entering and exiting the adjustment process mode
(1) Before entering the adjustment process mode, press the "RESET" button or execute the AV position
RESET in the video adjustment menu.
(2) Pull out the AC cord to turn off the TV.
(3) While holding down the "VOL (–)" and "INPUT" keys at a time, press the POWER switch of the main unit to
turn on the power.
The letter “ K ” appears on the screen.
(4) Next, hold down the "VOL (–)" and "CH (
Ù
)" keys at a time.
When multiple lines of blue letters are displayed on the screen, the unit has entered the process adjustment
mode.
If the unit does not enter the process adjustment mode (if the same display as the normal start appears), try
again.
(5) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to
make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC
cord and plug it again. In this case, wait 10 seconds or so before plugging.)
Caution: Use due care in handling the information described here lest your users should
know how to enter the adjustment process mode. If the settings are tampered in this mode,
unrecoverable system damage may result.
