Can be used in hospitals, schools, shopping malls, companies, warehouses, residential, home and other places
– Compact, size: 102 * 60 * 30mm
– Good performance and low cost, easy to install
1 Connect the power adapter to the transmitter (2A), plug in the power, the red light, proved successful powered transmitter;
2 would be another power adapter connected to the receiver input (1A), plug in the power, the red light, proved successful powered receiver;
3, with audio / video cable to the transmitter and the signal source (such as DVD, camera) phase, receiver and display phase, transmitter, receiver, channel s
Special Note: The frequency of the transmitter must be connectedSame frequency receiver, (where the transmitter and receiver must be the same red DIP switch) or no signal is received!
If you use the 2.4G audio / video wireless transmitter when there are still problems, please carefully read the user instructions. Here are solutions to some common problems.
5.1 No picture or sound
a. Check that the power adapter is connected correctly
b. power key is adjusted to the correct position
c. Check the connection cable is intact, the connection is correct
5.2 the interference image and sound
a. slowly move the transmitter and receiver to the best AV receiver position
b. shorten the distance between transmitter and receiver
c. checking whether the receiver near the radio frequency interference, such as microwave ovens.
d. If the receiver near radio frequency interference, change channels in order to achieve the best results
e. Check whether the transmitter and receiver to the same channel
5.3 Can not remote video source
a. Check the remote control batteries are charged
b. determine whether the alignment of the infrared remote control receiver window
c. determining transmitter and the receiver, the distance between the receiver and transmitter in the valid range.
A, the machine uses voltage
