Futaba 4EXA - Manual (Page 2)

22
INTRODUCTION INTRODUCTION
Thank you for purchasing the Futaba ® 4EX digital proportional R/C aircraft system. If this is your first “ computer ” radio, rest
assured that it is designed to make initial setup and field-tuning of your airplane easier and more accurate than would be if
using a “ non-computer ” radio. Although this is a beginner or sport system with the requirements of those flyers in mind, in
order to make the best use of your Futaba 4EX and to operate it safely, you must carefully read all of the instructions.
Suggestion:
Suggestion: If, while reading the instructions, you are unclear of some of the procedures or functions and become “ stuck, ”
continue to read on anyway. Often, the function or procedure will be explained again later in a different way providing another
perspective from which to understand it. Another suggestion is to connect the battery, switch and servos to the receiver and
actually operate the radio on your workbench as you make programming changes. Then, you ’ ll be able to see the effects of
your programming inputs.
