User’s Manual 240240 2.4GHz Wireless TV Box Contents Contents 27 Precautions 7. Precautions 7.1 Normal phenomenon Interruption appears while moving. Please move to a fixed place to watch. As adopting RF control technic, there will be momentary interruption in the picture when using remote control. The transmission distance varies according to the surroundings; the distance of ordinary house is about 10-20 meters. But if the wall is of iron and concrete, it will largely muffle the signal (can not receive signal or shorten receiving distance) 7.2 Using precautions 2.4GHz domestic appliance (such as micro oven, 2.4GHz cordless phone, Bluetooth earphone, or 802.11b/g wireless network) may affect the quality of receiving even cause no signals receiving. If affected by micro oven, the receiver should be put far from it. As for other interruptions, you can reset the signal channel of the transmitter and receiver. The transmitter should be put on a higher place to get better transmission effect when there is no obstacle around the transmitting antenna, thereby the transmission distance will become longer. It can also reduce the interruption from our moving when the receiver is placed higher. 1 Introduction Combining 2.4GHz wireless technic and USB TV box technic, UTV240 is known as a Hi-Tech product.

Circuit Description This passage is mainly on how UTV324 wireless A/V receiver works and is divided into two parts: The first part is 2.4GHz A/V receiving: 2.4GHz receiving module of UTV324 demodulate 2.4GHz signal into A/V signal and output them to SAA7113 and EMP202, which convert them into digital signals. These digital signals are transmitted to EM2860 and then converted into USB data which is transferred to PC; The digital signal will be displayed via TRV PLUS software. The second part is 433MHz ASK signal transmitting: The remote signal from signal source is converted into digital signal via UTV324 remote receiver. After encoded by MCU EM78P447, the digital signal will be demodulated and emitted via 433MHz transmitting module.
