(4) If receiving condition is not good, extension cord and high gain antenna can be adopted， or even to add antenna amplifier to get a very obvious long distance transmission effect. (5) When receiver panel face to the application direction, or that when receiver is put in metal box, connect the antenna to front panel shall gain a better receiving effect.
