Руководство Пользователя для Samsung SCH-3500

To avoid accidental key presses,  you can enable the 

KeyGuard feature.  However, you’ll still be able to receive 

incoming calls and messages.  This feature also prevents 

needless battery usage because the phone does not 

respond to any keypresses and turns off the backlight. 

Note:  If you have an incoming call, open the flip to answer 

it.  When you are done with the call,  close the flip and 

KeyGuard is automatically turned on.

To activate KeyGuard:

1. Press   to display the Main Menu.

2. Press   for KeyGuard.  The keypad locks and 

“KeyGuard” displays.

3. Press and hold   to deactivate KeyGuard,  or simply 

open the flip to turn on the backlight and temporarily 

disable KeyGuard.

Note:  KeyGuard works only when the flip is closed.
