About

In order to avoid unwanted or accidental activation of the keyboard, a lock/unlock mechanism has been implemented. This means that the 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 keyboard is locked.

After unlocking the 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-out (10 seconds), the keys will dim again and the keyboard will re-lock.

To unlock the keyboard

Two options are available to unlock the keyboard:

1. Option 1: Press and hold (0.5 seconds) the keyboard unlock button () at the bottom of the display until the entire keyboard starts blinking slowly. Afterwards, release the key again (within 2 seconds) to avoid a keyboard re-lock.

   

2. Option 2: Press and hold (3-4 seconds) the key until the entire keyboard starts blinking slowly. Afterwards, release the key again (within 2 seconds) to avoid a keyboard re-lock.

To lock the keyboard

The keyboard will automatically lock after 10 seconds of inactivity, except while navigating the OSD menu, during which it remains unlocked.
