This W150T runs off 12V as well as Mains. It also has built in Common Interface slot which will allow you to view certain pay per view channels such as Setanta Sports when purchased. Freeview is also built into the TV meaning there is no need for an external set top box. With freeview comes the ability to go interactive (Red button). 2 X HDMI slots are also built in meaning you can view your favourite channels in High Definition for better viewing. Another feature of the Avtex TV is that it can be used as a PC monitor. To round it off and make your life easier the Avtex now has a 1 button tune in, by simply holding down the AQT button on the remote control for 3 seconds in either digital or analogue TV mode the TV will automatically tune itself in! Further, with sets that have MHEG5 the added advantage is that all the channels are saved in the correct order! This feature is ideal for tourers, what could be simpler?
