Pay Attention: AT10II is default 12 channels, you have to setup AT10II to 10 channels first if you
use receivers R6DS, R6DSM, R9DS and R10DS.
How to setup to 10 channels transmitter: power on your AT10II--Press Mode button one second to
into BASIC MENU--into SYSTEM menu--change CH-SELECT from 12CH to 10CH.
Since Radiolink radio control systems are not open source, that Radiolink transmitters just
compatible with Radiolink receivers and vice versa.
1.1.4 RSSI testing
Power on transmitter and receiver, keep transmitter apart from receiver about 30 centimeters and
the antenna straight.
Into the parameter setup menu by press MODE one second, you can check the RSSI in RECEIVE
menu.
The RSSI is 0 to 30dBm is normal when the transmitter is apart about 30 centimeters from the
receiver, the signal is more better the RSSI data is more close to 0.

1.2 RADIO INSTALLATION
1.2.1 Guidelines to mount the servos, receiver and battery
•Make certain the alignment tab on the battery, switch and servo connectors is orient correctly and
‘key’ into the corresponding notch in the receiver or connectors before plugging them in .When
unplugging connectors, never pull on the wires. Always pull on the plastic connector instead.
• Receiver’s Antenna: In generally receiver’s antenna is longer than remote control, don’t break or
retract it, otherwise shorten the control distance. The antenna must be kept away from conductive
materials, such as metal. Please make distance test before flying.
• If your aileron servos are too far away to plug into the receiver, use an aileron extension cord to
extend the length. Avoid plugging multiple extensions together to obtain your desired length. If the
distance is greater than 50cm or high current draw servos are being used, use heavy servo
extensions.
• Receiver Vibration and Waterproofing: the receiver contains precision electronic part. Be sure to
avoid vibration, shock, and temperature extremes. For protection, wrap the receiver in foam rubber
or other vibration-absorbing materials. It is also a good idea to waterproof the receiver by placing it
in a plastic bag and securing the open end of the bag with a rubber band before wrapping it with
foam rubber. If you accidentally get moisture or fuel inside the receiver, you may experience
intermittent operation or a crash. If in doubt, please contact Radiolink after cares or distributors for
service.
• Always mount the servos with the supplied rubber grommets. Don’t over tighten the screws. No
part of the servo casing should contact the mounting rails, servo tray or any part of structure.
Otherwise vibration will be transmitted to the servo causing damage of servo. Note the small
numbers (1, 2, 3, and 4) molded into each arm on the servo arms. The number indicate how many
degrees each arm is ‘off’ from 90 degrees to correct for minute manufacturing deviations from servo
to servo.
• To center the servos, connect them to receiver and turn on the transmitter and receiver.
Center the trims on the transmitter, then find the arm that will be perpendicular to the pushrod when
placed on the servo.

Radiolink Electronic Ltd

• After the servos are installed, operate each servo over its full travel and check that the
pushrods and servo arms don’t bind or contact each other. Also make sure the controls do not
require excess force to operate. If there is an objectionable buzzing sound coming from a servo,
there is probably too much resistance in the control. Find and correct the problem. Even is there is
no servo damage, excess battery drain will result.
• Use the mounting plate from the receiver on/off switch as a template for the cutout and screw
holes, mount the switch on the side of the fuselage opposite the engine exhaust, and where it won’t
be inadvertently turned on or off during handling or storage. Be certain the switch moves without
restriction and ‘snaps’ from ON to OFF, and that the cutout allows full motion of the switch in both
directions.
• When install the switch harness to the helicopter please use the switch cover. Generally
sandwich the frame between the switch and switch cover and securely tighten the screws, Different
models might require different installations. If so, please follow the model’s instruction manual.
• To prevent the servo lead wires from being broken by vibration during flight, provide a slight
amount of slack or extra so that the wire sticks out slightly and fasten it at suitable points. In addition,
periodically check the wire during daily maintenance.

The above listed receiver and channels is referred to the channel 1~11 of the receiver R12DS,
connect the receiver with the related servo, you can control the servos by the correspondent switch.
To be clear, the servo connected with the receiver channel 1 is controlled by the radio aileron lever,
servo connected with channel 2 is controlled by elevator lever, servo connected with channel 3 is
controlled by throttle stick, servo connected with channel 4 is controlled by the rudder lever.
Channel 5~11 can be self-set with the related switches by the menu AUX-CH, and the sub menu.
For SBUS signal channel, is output by the 3 pin of 12 row.
Signal working modes:
There are two signal working modes, PWM and SBUS&PWM signal output. Short press ID SET
twice within 1s, the working mode will change.The RED led indicates the PWM output and
BLUE/PURPLE led indicates SBUS signal.
(1) PWM signal output working mode：RED led indicates PWM signal output, 11 channels totally.
(2) SBUS&PWM dual signal output working mode: BLUE/PURPLE led indicates SBUS&PWM
signal output at the same time with 12 channels totally. SBUS signal channel(3 pin of row 11)
outputs 12 channels of SBUS signal while PWM signal channels(3 pin from row 1 to row 10, i.e CH3
to CH12) output PWM signals with 12 channels in total. The actual channel quantity of PWM signal
output depends on that of SBUS signal output used. Eg. If 4 channels of SBUS signal output used,

then there are only 8 channels of PWM signal output left.
1.2.3 Installment of antenna
1. Receiver Antenna Installment
1Keep antennas as straight as possible and 90° as below, or the effective control range will
reduce.
2Big models may contain metal parts that influence signal emission. In this case, antennas should be
positioned at both sides of the model to ensure the best signal status in all circumstances.

Radiolink Electronic Ltd
www.radiolink.com
11
3Antennas should be kept away from metal conductor and carbon fiber at least half inch
away and no over bending.
4Keep antennas away from motor, ESC or other possible interference sources.
Note Receiver contains some electronic components of high-precision. Be careful to avoid strong
vibration and high temperature.
When all the above steps are complete, please turn off the transmitter and repower on to test if the
receiver is correctly connected with it.
2. Transmitter Antenna Installment
1The transmitter antenna is adjustable so please make sure that the antenna never points
directly at the model when flying as this may possibly decrease the receiver signal.
2Keep the antenna perpendicular to the transmitter to optimize the receiver performance. It
also depends on how you hold the transmitter. But in most cases, adjusting the antenna with
perpendicular position to the transmitter surface will achieve the best result. Please adjust the
transmitter antenna according to the way you hold the transmitter.
3Never grip the antenna when flying as this degrades effective control range.
1.3 RADIO BASIC SETTING
1.3.1 Basic setting of the transmitter
(1) Display language: can be selected the display language of the function name, etc. in each
function menu. The screen reads "LANGUAGE". Change this to the desired language.
(2) Stick Mode: The screen reads "STK-MODE". Change this to the correct mode. Note that this will
NOT change the throttle and elevator ratchets, etc. Those are mechanical changes that must be

1.3.3 Binding
Each transmitter has an individually assigned, unique ID code. Receiver should bind to
transmitter before starting operation. Once binding is complete, the ID code will be stored in the
receiver and no further binding is necessary unless the receiver is used with another transmitter.
When you purchase a new R12DS, this procedure is necessary; otherwise the receiver will not
work.
1. Put the transmitter and the receiver close to each other within 50 centimeters.
2. Power on AT10II and receiver R12DS. The RED LED will be on.
3. Turn on AT10II and it will automatically bind to the closest receiver.
4. There is a black binding button (ID SET) on the side of receiver. Press the button for more than
1 second and release, the RED (by default, could be Purple for SBUS&PWM signal output) LED will
flash, meaning binding process is ongoing.
5. When the LED stops flashing and is always on , binding is complete.
Make sure servos connected with the receiver can be operated by the transmitter.
Note
AT10II is default 12 channels and can be changed to 10 channels. In order to bind to non
12-channel receivers(R6DS,R6DSM,R9DS), channel quantity needs to change to 10 channels.
How to setup the channel quantity of the transmitter: power on AT10II--Long press MODE to enter
BASIC MENU-- Toggle the CURSOR to select and enter SYSTEM --change CH-SELECT from
12CH to 10CH.
Since RadioLink radio control systems are not open source, that RadioLink transmitters are
ONLY compatible with RadioLink receivers.
1.3.4 Transmitter Displays & Buttons
When you first turn on your transmitter, a confirmation double beep sounds, and the screen
shown below appears. Before flying, or even starting the engine, be sure that the model type and
name appearing on the display matches the model that you are about to fly! If you are in the wrong
model memory, servos may be reversed, and travels and trims will be wrong, leading to an
immediate crash.

Warning and error display
When the transmitter is powered on, warning or error may happen by the following probability:
1. Battery low voltage alarming
Lithium battery 2S-4S can fit for the transmitter, warning voltage can be self-set according to
different battery.
Setting step: power on the transmitter, press and hold MODE one second to enter basic menu,
and press PUSH to enter PARAMETER. Choose TX ALARM by DIAL and PUSH to change relative
data. Suggested min voltage is not less than 7.4V.
When the transmitter voltage is less than the setting voltage, it will beep till the transmitter is
powered off. Most important thing is to land your model plane when the transmitter alarms.
2. Mixing alarm
When the transmitter alarms mixing, it means at least one mixed switch is active. And when it is
inactive, warning will stop then. When the transmitter is powered on, in different model type, mixing
switch is shown as below:
ACRO: throttle cut, idle down, snap roll, air brake
GLID: butterfly, condition
HELI: throttle cut, throttle lock, speed up
If the warning continues even the related switch is set OFF, probably it is because some programs
mixed by one switch and status OFF reversed. Now you need to set mixing alarm again by DIAL.
PART 2. BASIC FUNCTION OF AIRPLANE
Please pay attention that the (BASIC) menu is suitable for all type models (airplane, helicopter,
glider, multicopter). The motor cut will be introduced in Glider (Basic) Menu, except Idle down
&Throttle cut. Helicopter Basic Menu include some extra function (swash plate tilting, throttle and
pitch curves and the tail rotor anti torque mixing under normal flight model) will be discussed in
Helicopter section.
