*Note: The RF Transmission Indicator will not be on when the
display switch is activated. Also it wll not be illuminated when
there is not a module installed in the transmitter.
**Note: Steering Tension is adjustable via the Phillips head
screw recessed next to the idle up switch. Screwing clockwise
increases the steering tension.
Display Switch
The display switch allows the input of data without transmit-
ting a signal. This is useful for making adjustments while
not affecting others that may be on the same frequency. With
the power switch off, turning on the display switch will acti-
vate the display and all programming functions can be
accessed. This also uses about 2/3 less power; if you plan
on working with the programming for a while, using the dis-
play switch will save batteries.
Note: The antenna included with the R-1 is the screw-in
type (part #JRPA160). When in use, be sure the
antenna is screwed in firmly, and the antenna is
extended fully.

changing of frequencies or bands. To remove the module,
press the tabs located on the module inward while pulling
the module out. Replacement crystals and modules are
available separately, allowing frequency changes to be
made.

Installing the Batteries
The R-1 transmitter requires 8 AA batteries (not included).
To install the batteries, remove the battery door on the bot-
tom of the transmitter and install the batteries such that the
coil spring in the battery holder contacts the negative (flat)
side of the battery. Alkalines will provide power for approxi-
mately 7 hours of use. An optional rechargeable Ni-Cad bat-
tery pack is also available separately
(part #JRPB9280).
CAUTION! When charging Ni-Cads in the R-1, note
that the charge jack is center pin negative (see
diagram below). Be sure to use a JR charger or
verify that the charger you’re using is center pin
negative before charging. Typical slow charge
rates are 50mA for 12 hours, while most Sanyo
brand AAs can be charged at up to 1 amp. Be
sure to use a reliable peak charger if you’re fast
charging your transmitter and remember the cen-
ter pin is negative!
D.S.C. (Direct Servo Control)
The R-1 features a D.S.C. function that allows the operation of
the servos/speed controller without transmitting a signal. This
allows testing and adjustment of the radio/speed controller
without affecting others that may be on the same frequency.
Note: An optional D.S.C. cord (part # JRPA134) is
required to operate the D.S.C. function.
To operate, plug the male end of the D.S.C. cord into the
D.S.C. jack located under the panel on the front upper left of
the transmitter. The other radio connector end of the D.S.C.
cord is inserted in the battery slot in the receiver. Note: If
using a gas car, a Y harness will need to be used so the bat-
tery and D.S.C. cord can both be installed in the battery slot
on the receiver (part #JRPA133).
Now turn on the speed controller switch (electric) or the
receiver’s power switch (gas) while leaving the transmitter’s
power switch turned off. If nothing happens, you may need
to charge the batteries in your car.
The servos/speed controller should work normally while no
transmission is taking pace.
Note: Only JR brand receivers are compatible with the
R-1’s D.S.C. function. After-market receivers will
not work with the D.S.C. function.

General Information About
Programming the R-1
Beeping Confirmation
A beeping sound will be heard when inputting, verifying the
input is valid.
Two-Speed Scrolling
All the keys (except the clear key) feature two-speed scrolling.
Holding the key down for morethan 3 seconds will automati-
cally switch from low to high speed scrolling, which is helpful
when making large value changes in programming.
Contrast Adjustment of the Display
The contrast of the display can be adjusted by doing the fol-
lowing:
1. Turn on the power switch
2. Hold down the SEL key
3. Now, while holding down the SEL key, press the + key to
darken the display or press the - key to make the display
lighter.
Digital Trims
There are five digital trims on the R-1 (see page 4 for loca-
tions). Each digital trim is adjusted by pressing the trim but-
ton in one of the two available directions.
Note: A beep will be heard with each step of trim adjust-
ment. When passing the center, a different sound-
ing beep and a hesitation will occur, indicating
the center position. Also when the end of the trim
is reached, a different sounding (pitch) beep is
heard. Also note that the tone of the beep changes
from one extreme side of the trim to the other; this
change in tone allows you to know approximately
where the trim is set just by the relative tone of the
beep when a digital trimmer is adjusted.
Digital trim positions are automatically stored in memory
when switching from one model to the next.
The function of each of the five digital trims can be
programmed to one of the seven following functions: steer-
ing trim, steering dual rate, throttle trim, panic brake,
channel 3, A.B.S. swing, A.B.S. point.
Battery Alarm
When the battery voltage drops below 9.0 volts, BATT will
flash on the display and an alarm will sound five times.
When BATT appears on the screen, many of the
programming functions are disabled. Replace (AA) or
recharge (Ni-Cads) the batteries.
Warning Alarm
If the Drive Mode or Idle Up switch is in a different position
then when you last turned the radio off, an alarm will sound
warning of this condition and the display will indicate which
switch is at fault. Switching the offending switch to the
proper position will shut off the alarm and normal operation
is resumed. If this alarm function is not desired, it can be
turned off in Transmitter Mode function (page 25).
Back-Up Error
A built-in five year Lithium battery functions as battery back-
up should the main battery fail (for example, if the transmit-
ter was left on). This back-up battery will maintain all
programmed information. If 1 BACK UP ERROR appears on
the screen accompanied by an alarm sound, the Lithium
battery needs to be replaced and/or the unit needs repair.
Return the transmitter to the following address for lithium
battery replacement and repair:
Horizon Service Center
4105 Fieldstone Road
Champaign, IL 61821
217/355-9511
Fortunately, the Lithium battery conservatively lasts a good
five years, and by then it’s a good idea to have your radio
returned and checked out by our service technicians.
1 BACK UP ERROR

Note: Trim positions will appear here if D.T. display is
turned on in Tx Mode; ABS will appear here if it
is turned on.
When the normal display is shown, pressing the MODE
LIST key will access the Direct Mode. Then, by pressing the
UP or DOWN key, the menus in function list are accessible.
Each time the UP or DOWN key is pressed, it advances to
the next programming feature. Depending on what mode
you’re in, pressing the MODE LIST key several times will
bring up the function list that displays all the available
menus in function mode on a single screen (see page 11).
These can be scrolled through using the UP or DOWN key
to move the cursor and accessed by pressing the MODE
LIST key.

System Mode
Also called System Set-Up Mode, this mode con-
tains programming features that are usually only
adjusted once during the initial set-up of a particu-
lar car, and once set, they’re seldom, if ever,
changed at the track. System Mode programming
features include servo reversing, model name,
modulation type, data transfer, etc.
Note: When in a function, press the UP and DOWN keys
simultaneously to return to Normal display.
