Adjusting external device connections 
You can choose the level of control you want to allow your TV to accept from 
external devices, such as smart phones, tablets, and virtual assistants. Device connect 
settings enable other devices, including the Roku Mobile App, to control your TV over 
the local area network in your home.  
To adjust the level of external control access: 
1.  From the Home screen menu, navigate to Settings > System > Advanced system 
settings > Control by mobile apps. 
2.  Select Network access.  
3.  Choose one of the following settings: 
•  Default – Devices can connect only through a private network address, and 
accept commands only from other private network addresses on your 
home network. This setting is suitable for most cases, including use of the 
Roku mobile app on your smartphone.  
•  Permissive – Devices can connect under all conditions, but accept 
commands only from private network addresses or the same subnetwork 
within your home network. This setting might be required when attempting 
to operate the TV from a third-party application, for example, one of the 
Internet of Things (IoT) applications such as ifttt.com. 
•  Disabled – Device connection is completely disabled. The TV does not 
accept external commands from any source, including the Roku mobile app.
