Acer Aspire A3-600 User Manual - Page 18

Locking your A3-600 If you will not use your A3-600 for a while, briefly press the power button to lock access. This saves power and ensures your A3-600 does not unintentionally use any services. Your A3-600 will lock automatically if it is not used after a while. To change the delay, tap APPS > Settings > Display > Sleep. Waking your A3-600 If the screen is off and the A3-600 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 A3-600, 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 29. Shutting down your A3-600 If you won't use your A3-600 for an extended period of time, turn it off to save power. To turn off your A3-600 (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. 18
