INTRODUCTION TO THE 4EX SYSTEM
INTRODUCTION TO THE 4EX SYSTEM
IMPORTANT!:
IMPORTANT!: Always turn on the transmitter first, then the receiver. When turning off the system, always turn off the receiver
first. The object is never to have the receiver on by itself. Otherwise, the servos or control surfaces could be damaged, or in
the case of electric-powered models, the motor may unexpectedly turn on causing severe injury.
IMPORTANT!:
IMPORTANT!: Never collapse the transmitter antenna by pushing down from the top. If one of the segments becomes momentarily
stuck you may damage the antenna. Instead, collapse the antenna from the bottom, drawing in one segment at a time.
