Normally, the screen will sleep or turn off after a certain amount of time when your device sits idle for a while. This can bring disruption that you always need to unlock the screen to work with your device. However, PDF Reader Pro enables you to bypass the time limit with the Keep iPhone/iPad Awake function.

1. Go to Documents  and open a PDF file as needed to enter the reading page;

2. Click  in the top menu bar;

3. Tap on the Keep iPhone/iPad Awake toggle to turn on this function.
