CHAPTER 1 : USING THIS M ANUAL
•
Introduction
1
USING THIS MANUAL
In the beginning of this manual you will find the
specifications for the radio and its various
accessories. In addition, guidelines for the initial
installation of the accessories have been included,
as well as instructions for setting all the functions
and programs of the X-378 to suit your personal
preferences. These features are discussed in the
same order that they will appear on your radio,
as you will see on the accompanying charts. An
explanation of the use and purpose of each feature
is provided, followed by a labeled illustration of its
respective LCD display .
In addition, a step-by-step example clarify the setup
procedure of the feature. Practical applications for
many of the radio’ s features enable you to see their
true purpose and additional possibilities. A blank
data sheet has been included at the end of each
section. Once all data has been inputfora
particular model, it is highly recommended that you
record it on a copy of the sheet provided. If you
should experience memory loss or battery failure or
wantto make changes to the current settings, this
step will save you a great deal of time. Following
the data sheet, you will find information on
precautionary measures and general guidelines for
safe use of your new equipment.
Use of the Instructions with the Radio
While the X-378 has a dedicated or single-use switch
layout, it may be used for multiple model
types.
T
e mplates have been provided in this manual that
explain the different switch assignments when
using
the transmitter with the various air
, heli and sailplane
software.
CHAPTER 2 : FEA TURES
2.1
X-378 TRANSMITTER
The computer designed, ergonomically styled
transmitter case ensures a good, comfortable fit in
your hands. The ultra-precision control sticks offer
adjustable spring tensions and length. The throttle
s t i ck off e r s a ratchet in Airplane configuration for
smooth travel.
8 -m odel memory storage allows
programming of all characteristics of eight separate
helicopters, airplane or gliders; you can program
more than one setup for a single aircraft, allowing
you to instantly change the flight characteristics.
Afive-year lithium backup battery prevents loss of
memory in the event that the battery discharges
completely or is removed.
Features include automatic fail-safe "set" and
information update in PCM mode when fail-safe is
used. A programmable trainer function allows the
student to practice individual channels separately
.
Direct Servo Control (DSC) permits operation of
a ll t h e controls and servos without generating a
radio signal.
2.2
R700 RECIEVER
NER-700 (FM Systems)
The R700’ s is a high-performance FM or single-
conversion receiver with 10KHz super narrow band
ABC&W circuitry .
Anarrow band ceramic filter for high-signal
selectivity assists in rejecting cross modulations
from other common radio frequencies-e.g., R/C
transmitters, local paging systems. This receiver
features Direct Servo Control (DSC) for control of
surfaces without radio frequency output.
The receiver has low current consumption.
The R700's Slimline design allows it to fit into most
model applications.

CHAPTER 4: BA TTERY CHARGING
4.1
TRANSMITTER/RECEIVER
Note: It is imperative that you fully charge
both the transmitter and the receiver battery
packs priorto each flight. T o do so, leave
the charger and batteries hooked up overnight
(16 hours). The first charge should be
approximately 20–24 hours in order to fully
charge both battery packs to peak capacity
.
RIGHT SIDE OF TRANSMITTER
The charger supplied with this system is
designed to recharge your batteries at a rate
of 5mAh for the transmitter and 50mAh for
the receiver battery pack.
CENTER
PIN IS
NEGATIVE
Tr ansmitter Only
The center pin on all JR Remote Control Systems is
negative. Therefore, the center pin on all JR chargers
is negative, not positive. This is different from many
other manufacturers' chargers and radio systems.
Beware of improper connections based on "color
-
coded" wire leads, as they do not apply in this
instance. Y ou must make sure that the center pin of
your JR transmitter is always connected to the
negative voltage for correct polarity hookup.
OUTSIDE IS POSITIVE
CHARGER PIGT AIL FOR TRANSMITTER
BLACK TO POSITIVE
RED TO NEGATIVE
CHARGER PIGTAIL FOR RECEIVER
Important: Please note that the charging
polarity of the transmitter and receiver are
different.
RED–POSITIVE / BROWN–NEGATIVE / ORANGE–SIGNAL
4.2
CHARGER
The pilot lamps should always be on during the
charging operation. If not, check to make sure that
both the transmitter and receiver are switched off. Do
not use the charger for equipment other than JR. The
charging plug polarity may not be the same.
Equipment damage can result.
Do not use other manufacturers' after - market
accessories that plug into the transmitter's charging
jack. If you do, any damage that results will not be
covered by warranty . If you are unsure of compatabily
issues with your radio, seek expert advice before
doing anything to avoid possible damage. During
the charging operation, the charger's
temperature is slightly elevated. This is normal.
Also, note that the voltage shown on the charger is
higher than the battery in use. This voltage cannot
be measured with a voltmeter. Only current can
be measured with any accuracy using this type
of charger .
Be sure to use the proper charger (120mAh)
when using battery packs of 1000mAh or larger for
yourreceivers.
X-378 MANUAL Introduction 7

4.3
ADV ANCED DIGIT AL TRIMS
Y our new X-378 system employs four digital trim
levers for unmatched precision and adjustability .
By using the T rim Step function located in the
System mode, the movement of the ADT trims
can be fine tuned as needed to match your
specific application.
The ADT feature is also designed to automatically
save the determined trim values for each model.
When the X-378 is changed between models in the
Model Select function, the digital trim values will
automatically stay with each model, eliminating the
need for a separate trim memory function.
will automatically change to display the numeric
value, as well as the graphic position for the trim
being adjusted.
The X-378's digital trims also feature 2-speed
scrolling . When a substantial amount of trim is
required, holding the trim in the desired position
will activate the dual speed scrolling function. The
X-378's Aileron, Elevator, and Rudder trim
levers
(also throttle in sailplane mode) feature
an audible center trim beep. This is helpful in
determining the trim levers center position
duringflight.
The X-378's digital trims also feature the Direct
Access display function. While at the Normal
displayscreen, if a trim leveris moved, the screen
Please also note that unlike conventional
mechanical trim levers, when the X-378 transmitter
is in the off position, no changes can be made to
the
trim values during transportation.
One T ouch Digital Throttle Tr im Lever (Air and Heli Modes only)
The X-378 also features a revolutionary One-T ouch
Digital Throttle Trim lever . While in Air or Heli modes,
the X-378 will remember the maximum high Throttle
T
rim position (usually idle) set from the previous
flight. At the end of the flight, move the
Throttle T rim
to the full low (engine off) position.
For the next
flight, by simply pressing the Digital
Throttle T rim up
once, the throttle trim value will
automatically move
to the position from the
previous flight. Trim value
changes can then be made by moving the throttle trim
lever as needed.
The Direct Access Digital T rim
function will display
the throttle trim value
numerically and also
graphically on the screen automatically each time
the Throttle T
rim is moved
This feature is very helpful as once you have set the
correct throttle trim value for a proper idle, the
X-378 will allow the Trim lever to be set back to this
position for each flight, eliminating the need to set
the exact throttle trim value for each flight.
Note : When the X-378 is in the glider
(sailplane) model type, the Digital Throttle
T rim works as a conventional trim lever, which
is the most desirable method in this mode.
