3.2 Front keyboard locking/unlocking

About

In order to avoid unwanted or accidental activation of the front keyboard, a lock/unlock mechanism has been implemented. This means that the front keyboard needs to be unlocked before it can be used to change any of the display settings. By default, all keys except the key will be dimmed to indicate that the front keyboard is locked.

After unlocking the front keyboard, all keys will light up. Touching any of these keys while the backlight is on will execute the function of the key. However, if no further action is taken within the time defined by the OSD time-out parameter, the keys will dim again and the keyboard will re-lock.

To unlock the front keyboard

Two options are available to unlock the keyboard:

With the front keyboard:

  1. Press and hold (3-4 seconds) the key until the entire front keyboard starts blinking.
  2. While the front keyboard is blinking, release the key again (within 2 seconds, to avoid a keyboard re-lock) and the front keyboard will be unlocked. Also the front menu will automatically appear.

With the rear keyboard:

  1. Press any key on the rear keyboard and the front keyboard will be unlocked.
To lock the front keyboard

The front keyboard will automatically lock after the time of inactivity defined by the OSD time-out parameter, except while navigating the front or OSD menu, during which it remains unlocked.
