3.5. Lock Function 
Sometimes you want to be able to lock the device’s inputs, for instance if listening to music 
and carrying the player in your pocket, to avoid unwanted inputs.  It is possible to lock the 
Sansa Fuze+ MP3 player’s touch pad. 
To lock the device, do a quick press on the power button.  A longer press will turn the 
player off and on.  All the function keys will be disabled once lock is engaged.  Please note 
that the Lock function only works when the player is turned on. 
The following image will appear on the display screen if any button, except for the volume 
button, is pressed while the device is in the locked mode.  The music should continue to 
play even if the device is locked. In addition, you can adjust the tactile volume in lock 
mode. 
To unlock the player, quickly press the power button again. 
   
 
Locking the device is quick and easy.  Quickly press the power button to lock and unlock the 
player.  A slightly longer press will turn the device off.  We highly recommend that when the 
device is playing in your pocket or is susceptible to receiving unwanted inputs while you are 
enjoying your listening, that you lock the device.
