control or buttons on the panel to operate in user mode, but only Remote control works in
factory mode.
The way to enter factory mode：Press “D-MODE”button on RC， press“OK”and
“CH+”“ CH-”to select the parameter you want to adjust.， Press“VOL+”“ VOL-” to
change the parameters. To quit factory mode，press“D-MODE” button（on the right of
SURR button），the factory data changed will be memorized.
A few special modes：
Aging mode — used before the aging before alignment. The aging could start in
factory mode.
Vertical stop mode—used to confirm the screen voltage. Press “INPUT”button in
factory mode to enter Vertical stop mode. Then press “INPUT”
button again to exit.
