To unlock the keylock, hold down the key again for at least one second.
If the key lock mode is set to "Password", you are asked to input your password.
If the key lock mode is set to "No password", you are not asked to input a password.
When any key is pressed with the keys locked (with key lock mode and "password" selected), the password input screen is
displayed.
When you input the correct password, the keylock is temporarily released and button operations become possible.
After the end of the button operations, the display returns to the standby screen and the keys are locked again.
