XF421EX MANUAL • INTRODUCTION 1: Using This Manual / INTRODUCTION 2: Features
The XF421EX is a full feature introductory computer
radio that can be used for airplanes.
A blank data sheet is included at the end of this
manual. Once you have input all the necessary data
into your transmitter for a particular model, we strongly recommend that you write that information
down on a copy of the data sheet provided. This is to
insure that, in the rare case of a memory failure, you
will not lose your data.

R600 Receiver
•
The R600’s extremely compact size allows it to fit
easily in limited spaces.
•
An independent laboratory ranked the R600
receiver with JR’s patented ABC&W circuitry as
one of the best receivers ever tested in terms of
3IM, 2IM, adjacent channel rejection, signal-to-
noise ratio, and on-channel capture point.
•
A special “unwanted interference limiter” ignores
signals outside of the R600’s band width when
the receiver is on and the transmitter is off. The
limiter also prevents servos from random
glitching when other transmitters are operating
in close proximity.
•
The electrical circuitry in the R600 is state-of-the-
art surface mount technology (SMT). These SMT
components draw less current, thus increasing
flying time. Flush mounting of these components
also reduces the risk of vibration wear and
damage.
•
The R600 is compatible with all JR FM-
transmitting radios.
