Remark:
1. The transmission distance may be different, and depend on surroundings, radio wave conditions, buildings,
etc., the 1000 meters transmission distance may be not guaranteed.
2. The wireless transmission might be interrupt if there’re many other devices of 5GHz wireless bandwidth
operated in the in the same location.
3. Signal reception may be affected by the position, height and angle of devices. If reception video is not stable,
please physically adjust placement for the optimized signal.
4. Open the antennas at various angles and set receiver higher will enhance the transmission efficiency.
5. The product offers the A S 128-bit encryption to protect the wireless transmission. Anyway, please be ware
of the intentional capture from third person.

Frequency Dial Switch
1. Using ONE set of devices under the same environment
Dial the frequency switch of both transmitter and receiver to the same channel (transmitter dial number same
to receiver digital display number), the default channel number is “0”:
S-4904T S-4990
2. Using TWO sets of devices under the same environment
It is suggested that set the dial switch of the first set to channel”0” and the second set to channel “5”
S-4904T #1 S-4990 #1 S-4904T #2 S-4990 #2
3. Using THREE sets of devices under the same environment
It is suggested that set the dial switch of the first set to channel”0”, the second set to channel “4” and the third
set to channel “7”:
S-4904T #1 S-4990 #1 S-4904T #2 S-4990 #2 S-4904T #3 S-4990 # 3
Note: 1. Please don’t use more than 3 sets of devices under the same environment to avoid interference.
2. To use multicast, just set several receivers at the same frequency channel as the one transmitter.
