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-out (10 seconds), 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.
