Read a lot, say, press MUNE long, press 10 seconds to unlock... My monitor does not ah.. that there are other ways, not to mention customer service!
Turn off the monitor first, press and hold (do not leave) menu key menu, then press the power button to start the machine, then press menu to adjust
There is a problem with the key button. You can try without the key. They unlock most of the unlock methods. They should be correct. Maybe there is something wrong with the button
Just hit the phone, asked to solve, first turn off the monitor, and then press and hold MENU do not put at the same time, press the switch to open, you can not, try several timesAnyway, I'll press it once
