21 Locking your TA272HUL
Locking your TA272HUL
If you will not use your TA272HUL for a while, briefly press the power button to lock
access. This saves power and ensures your TA272HUL does not unintentionally use
any services. Your TA272HUL will lock automatically if it is not used after a while. To
change the delay, tap APPS > Settings > Display > Sleep.
Waking your TA272HUL
If the screen is off and the TA272HUL does not react to any taps on the screen, then
it has been locked and is in sleep mode.
Security options
For additional security, you may set a code or number that must be entered to
access the TA272HUL, such as an unlock pattern (a set of dots that must be tapped
in the correct order). Open the Home screen and tap APPS > Settings > Security >
Screen lock.
Note: If you forget an unlock pattern, please refer to "Unlock pattern" on page
32.
Shutting down your TA272HUL
If you won’t use your TA272HUL for an extended period of time, turn it off to save
power. To turn off your TA272HUL (even when locked), press and hold the power
button for one second. You will then be asked to confirm the shut down. To force a
shutdown, press and hold the power button for four seconds.
