PCM9XII
he JR PCM9XII uses the latest Computer and Display Screen technology to enhance and extend the Radio Control user's
modelling experience. New to the PCM9X range is the Scroll Bar interface. In conjunction with the side entry buttons,
the new Scroll Bar provides a quick, convenient and efficient programming environment.
Information Display Screen
The PCM9XII Transmitter has facilities for three model types, (Helicopter, Fixed Wing power and Glider), with specialist
features particularly applicable to each. The relevant chapters give full details of the facilities that are available for each type
of model. We strongly recommend that, before attempting to programme the transmitter, you read Chapter 1 for the
System Menu information and the relevant following chapter, for the Function Menu details.
SCREEN CONTRAST ADJUSTMENT
It is possible to alter the display contrast to compensate for varying ambient light conditions. To change the display
contrast, rotate the Scroll Bar until the "DISP CONT" (display contrast) is selected (dark background) and click to select the
function. The dark background changes to a box surrounding "DISP CONT" to indicate that it is selected. Rotate the
Scroll Bar to the right to darken the screen or to the left to lighten the screen. When the required setting is achieved, click
the Scroll Bar to exit the sub menu. Of course if the change is taken too far, the screen display cannot be seen! No need to
panic - simply rotate the Scroll Bar or press the CLR (clear) key and the display will re-appear. If it does not, switch off,
switch on again, click the Scroll Bar to select the contrast function and press the CLR key to reset the screen. This will
always work as the contrast function is automatically highlighted when switching on.
SWITCH WARNING
As a safety feature, switching the transmitter on with a Flight Mode or Throttle Hold switch in other than the normal
position, causes a warning to be given. A pulsing beep signal is sounded and a flashing "SWITCH WARNING!" message
shows on the screen. The transmitter will not continue until the offending switch is moved to the normal (safe) position.
For convenience, the screen displays the name of the switch or switches causing the warning.
THROTTLE A.L.T.
The throttle trim employs a special Asymmetric Limited Travel feature that inhibits the throttle trim when the throttle stick
is in the upper half of its travel. The engine tick-over setting is adjusted by the throttle trim without affecting the full
throttle position.

MENU SYSTEM
The PCM9XII Transmitter settings and functions are controlled from within two major menu systems:
SYSTEM MENU LIST - The menu contains settings such as wing type, switch assignment etc., relating to the model
type. Some sections of the Function Menu only appear when their corresponding section is activated in the System Menu
List. To access the System Menu List (SYSTEM M.), start with the transmitter switched off. Press the ENT (Enter) key
and while holding it down, switch the transmitter on. The System Menu List is displayed.
FUNCTION MENU - The menu contains settings such as servo travel adjustment, sub trim, servo monitor etc., that
might be viewed or adjusted on the flying field. To enter the Function Menu, press the LIST key. The Function Menu List
is displayed.
Transmitter Layout
SCROLL BAR INTERFACE
IMPORTANT - Rotate the Scroll Bar by resting the thumb on the bottom of the bar, half on the bar and half on the bezel.
This will prevent accidental selections. Click the Scroll Bar by pressing the TOP of the bar.
The Scroll Bar is used to move the highlighted (selected) section of the screen through the menu choices. The Scroll Bar is
clicked to activate the highlighted menu item and where appropriate, produce a sub menu. Within any sub menu, the
highlighted menu choice is similarly moved and selected by rotating and clicking the Scroll Bar. On the lowest sub menu,

rotating the Scroll Bar will increment or decrement the figures. A Scroll Bar click is always used to exit from a sub menu.
When appropriate, block arrows on the screen point to any active side input keys.
INPUT KEYS
There are four keys on the left of the display. In conjunction with the Scroll Bar, they are used to navigate the menu
systems.
ENT (Enter) Used to gain entry into the System Menu List and direct entry into the last selected Function Menu
choice. From the System or Function Menu sub menus, it exits to the Information Display Screen.
LIST (List) Used to gain entry into the Function Menu. Returns the display, from a sub menu, to the Main Menu.
CLR (Clear) Returns a menu figure to the system default. When indicated, stores defined values.
Unmarked Screen display indicates function.
ADVANCED DIGITAL TRIM
When a Digital Trim lever is moved, the appropriate channel Digital Trim position is displayed on the screen for a few
seconds as a Bar Graph, vertically for Elevator and Throttle and horizontally for Aileron and Rudder. In addition, as the
value is changed, an audio indication of the trim position is given with a rising or falling tone. The tone and trim action
pause at neutral to assist in locating the neutral position.
The trim step rate may be varied as described in System Mode - Trim Step.
All Digital Trim settings can be automatically remembered for each Flight Mode so that separate trim facilities are not
necessary. See System Mode - DeviceSEL.
CONTROL STICK LENGTH
The stick units of JR radio equipment feature adjustable length sticks. Use the supplied allen key to make adjustments.
Loosen the grub screw by turning the allen key anticlockwise. Adjust the stick length to your requirement and lock the stick
in place by turning the grub screw clockwise. Please note that optional coloured sticks and long/short sticks are available
from your Local Model Shop.
CONTROL STICK TENSION
The stick tension may be adjusted to suit your preference. To adjust the tension, remove the RF Module, NiCad battery and
the back cover screws (six screws). Remove the transmitter back, being careful not to bend or damage the RF Module pins.
The tension screws protrude from the back of the stick assemblies, immediately adjacent to the tension springs. Adjust each
screw for the desired tension (anticlockwise to loosen the stick feel, clockwise to tighten the feel). Replace the back cover,
making sure that the side cheek levers are correctly located in the side cheeks and noting that the side cheek pads are
mounted with the slot towards the case back. Replace the RF Module and NiCad battery.
DSC LEAD
The Direct Servo Connection (DSC) allows the servos to be controlled without switching the transmitter on. The lead
bypasses the RF module and allows operation of the radio equipment without the danger of interference to other models.
To use the DSC connection, plug the DSC cable into the transmitter and then into the receiver’s charge lead. The
transmitter Information Display Screen will light but no RF will be transmitted. DO NOT TURN THE TRANSMITTER
ON! Turn the receiver ON to operate the servos direct from the transmitter.
Note: The DSC function will only operate with a JRC498D Deluxe Switch harness, or the JRC498 Heavy Duty Switch
harness. These switch harnesses include the orange signal wire, as well as the brown and red power wires.
BACKUP
The PCM9XII no longer utilises a Lithium Battery for backup. Model settings are now stored on Flash Memory that is
believed to have an unlimited life.

BATTERY CHARGING
The polarity of all JR transmitter charge sockets is to have the centre pin connected to negative. This is different to many
other manufacturer’s chargers. Beware of incorrect connections based on colour coded wires. We recommend that you
use only JR chargers with your JR system!
For peak battery capacity, the first charge should be for 22 – 24 hours. Thereafter, an overnight charge of 12 –14 hours will
bring the batteries to full charge.
Note that a diode is included in the charge circuit of the transmitter to prevent battery damage from incorrect chargers.
This also prevents the battery from being discharged through the charge socket and may prevent some "intelligent" battery
chargers from detecting the battery.
FUSE
The PCM9XII has a 3 amp internal fuse to protect the system in the event of a certain fault conditions. To replace the fuse,
remove the RF Module, NiCad battery and back cover screws (six screws). Remove the transmitter back, being careful not
to bend or damage the RF Module pins. The fuse is situated on the bottom left of the aerial PCB in the case back and
should only be replaced with a fuse of the same rating. Replace the back cover, making sure that the side cheek levers are
correctly located in the side cheeks and noting that the side cheek pads are mounted with the slot towards the case back.
Replace the RF Module and NiCad battery.
CHARGER
The charger supplied with your transmitter features two LEDs that light when the batteries are charged. If they do not light
when charging, make sure that both the transmitter and the receiver are turned off. During charging, the charger will rise in
temperature. This is normal and should not cause concern. If you have any worries about any of the charging equipment,
please seek expert advice. Please be sure to use the correct charge rate for your battery pack, any battery over 1000 mAH
should be charged at 120 mA.

INSTALLATION REQUIREMENTS
It is extremely important that your radio system is correctly installed in the model. Here are a few suggestions on the
installation of your JR equipment.
•Wrap the receiver in protective foam rubber that is no less than 10mm thick. Secure the foam to the receiver with rubber
bands. This protects the receiver from vibration and in the event of a crash or a hard landing.
•Mount the servos using the rubber grommets and brass bushes supplied. The brass bushes should be pushed into the
bottom of the rubber grommets, flange end towards the servo mount, after the grommets have been fitted to the servo.
When the servo screw is tightened securely, it provides the proper vibration isolation for the servo.
•Make sure that the control linkages do not bind or impede the movement of any of the servo arms as they must be able
to move freely over their entire range of travel.
•Mount all switches away from the engine exhaust and away from any high vibration areas. Make sure that the switch
operates freely and is able to operate over its full travel.
•Mount the receiver aerial firmly to the model to ensure that it will not become entangled in the propeller or control
surfaces.

Together with the Device Select (DeviceSEL) section, the Wing Type (Wing TYPE) screen provides access to the heart of
the PCM9XII transmitter.
•Flaperon (Ailerons also as Flaps) wing type may be selected.
•Delta (Ailerons and Elevator combined) wing type may be selected.
•V Tail (Rudder and Elevator combined) configuration may be selected.
•Dual servos, with included trim, may be activated for all primary channels (Aileron, Elevator, Rudder and Throttle) and
for the Flaps.
•For certain Auxiliary Channels, when Dual Servos are selected, an additional trim, active only on the Mate channel, may be
included.
The NORMAL wing type uses a single servo for each of the primary channels (Aileron, Elevator, Rudder and Throttle) and
they each plug into the appropriate receiver channel.
Two servos are required to utilise the Flaperon Wing type. The left wing servo plugs into the receiver Flap channel (Port 6)
and the right wing servo plugs into the receiver Aileron channel (Port 2). The servos move in opposite directions as

Ailerons and in the same direction as Flaps. Please note that if Dual Servos are required for the Ailerons, without the
Flap input, the Dual Aileron facility may be used.
With the Delta Wing configuration, the left wing servo plugs into the Aileron channel on the receiver (Port 2) and the right
wing servo plugs into the Elevator channel (Port 3). The servos move in the same direction as Elevators and in opposite
directions as Ailerons.
With the V Tail configuration, the left tail servo plugs into the Elevator channel on the receiver (Port 3) and the right tail
servo plugs into the Rudder channel (Port 4). The servos move in the same direction as Rudders and in opposite directions
as Elevators.
With a Twin Engine model, dual servos for the Throttle control (Twin Engine - Twin E.) are particularly useful as each
Engine is provided with its own Throttle curve and Trim.
Please note that Delta and V-Tail cannot both be active at the same time.
