Key Guard Mode
You can effectively lock the controls by entering key guard mode. By default,
your device is set to go into key guard mode after five minutes of idle time.
To enter key guard mode, do the following:
1 Press JUMP to open the Jump screen. Press MENU to open the menu,
scroll to highlight Key Guard, then press the wheel. You can also quickly
enter key guard mode by pressing and holding BACK for three seconds.
2 Your device control buttons lock and the key guard screen appears.
3 To unlock and wake the device, press MENU + BACK . If you have set a
privacy code (see next section), type it at the prompt. You can also wake
the device by opening the screen.
To prevent display damage, after your device has been in key guard mode for
two hours, a screen saver will appear. To dismiss the screen saver, press any
key or open the device.
To change the default key guard idle time setting:
1 Press JUMP to open the Jump screen. Press MENU to open the menu,
then select Settings > Key Guard & Security. The Key Guard & Security
screen opens.
