dear all, hope someone can help!!!Have just had my 6ex futaba tx exchanged for a safe one with all the correct stickers on the bottom,now the existing recievers wont go solid green and work at all as they did with the old tx i sent back…the recievers x 2 are r606fs 6 channel easy link that change from solid red to flashing green when switched on after the transmitter so have i been given a rogue tranny or am i not doing it right ? can’t see any recessed set up button on recievers Thanks in advance Roger
