6 Saving energy
DMS3-CTC-25-282 v1.0
Example
If we use the same example as in “6.1 Code of Conduct”, you can see that the TG789vac v2 is now able to dynamically reduce 
the power consumption in periods where less action is required from the TG789vac v2.
Wireless On/Off button
If you are not using the wireless access point of your TG789vac v2, you might consider to disable the wireless access point 
permanently. This allows you to further reduce the power consumption.
To turn the wireless interface:
• Off, press the Info ( ) button until the Info LED turns blue or the Wireless LED is off.
• On, press the Info ( ) button until the Info LED turns green or the Wireless LED is on.
Zero power consumption
If you will not be using your TG789vac v2 for a longer time (for example: you are going on holiday), you should consider to 
unplug the TG789vac v2’s power adapter from the power outlet. This way no energy will be consumed at all.
However, be aware that if you turn off the TG789vac v2, all services provided by the TG789vac v2 that require access to 
the Internet will not be available. For example:
• You will not be able to browse to Internet websites, listen to radio streams etc.
• No VoIP calls can be made/received
You will no longer be able to make or receive phone calls over the Internet. Your phone calls will automatically be done via 
the traditional phone network (if available).
• No Digital TV is provided
If your set-top box is connected to your TG789vac v2, it will no longer be able to connect to the Internet, hence not be 
able to service your TV set.
