JR X9303 Transmitter
Section 2: Transmitter and Receiver Specifications
Section 1: Using the Manual
G-9
JR’s X9303 2.4 offers airplane, helicopter and sailplane
pilots sophisticated programming that JR’s 9303 is
famous for with the added benefits of fully integrated
Spektrum 2.4GHz DSM
®
radio link technology. DSM
(Digital Spektrum Modulation) technology offers a far
superior RF link than narrow band 72MHz FM and PCM
systems, providing a higher level of confidence and
safety. Now with even the most sophisticated models
up to 9 channels, you’ll no longer have to wait for an
open frequency, worry about someone unintentionally
powering up on the same frequency, or have to plan a
frequency-based flight matrix for competition. And for
response-critical aircraft like 3D helicopters and airplanes,
latency (the time it takes for a stick input to translate to a
servo output) is significantly reduced providing a more
responsive precise connection to your model.

In the front of this manual you will find common
transmitter features and specifications plus information
on the included components and accessories. Guidelines
for receiver and servo installation are also included. In
each section of this manual (Air, Heli and Sailplane) are
instructions for adjusting model-specific programming
and functions. An explanation of the purpose of each
programming function is provided, followed by an
illustration of its corresponding LCD display and
instructions on how to access and adjust the function.
A blank data sheet has been included at the end of
each section, as well as on the JR web site. Once all
data has been input for a particular model, it is highly
recommended that you record these values and settings
on a copy of the data sheet, so in the rare event of a loss
of memory, these settings are available.
Note: The manual for the X9303 2.4 manual is posted
online at www.horizonhobby.com in the support section or
it can be ordered from your local hobby dealer or directly
from Horizon Hobby.
