Jumper
-
The jumper is installed at the factory and is used when the receiver is powered by an electronic speed
control, a commercially available B.E.C. (battery eliminator circuit), dedicated 4.8 to 6V, NiMH battery pack
or a regulated Li-Po battery. The jumper is removed when the receiver is powered using the SPC feature
as described.
Fail-Safe / Hold ( SRX 12, MRX 3 )
-
If the receiver signal somehow becomes interrupted or interference occurs, the servos will move to the
pre-set Fail-Safe point you previously stored in the Fail-Safe set-up. Make sure you set the Fail-Safe
function properly.
If Fail-Safe has not been activated, the signal will switch off after the Hold period of one second.
-
In the interest of safety, we recommend that the Fail-Safe function should always be activated, and the
Fail-Safe settings should be selected so as to bring the model to a non-critical situation
Please refer to Fail-Safe/ Hold page for more detail
Compatibility
-
SRX 12/ MRX 3 receivers are compatible with transmitter using Spectra G3 AFHSS 2.4Ghz system. Currently
Aurora 16 and Flash 14 are using Spectra G3 AFHSS 2.4Ghz system.
-
Aurora 9/ 9X, Optic 5/6/6 sports, Lite 4, Flash 7/8, Eclipse 7 pro are not compatible with SRX 12, MRX 3

Connection Diagram
Electric powered aircraft with Electronic Speed Control
Use this method on electric air plane using ESC’s providing power to the receiver and servo function.
(If ESC has no BEC circuit, please use separate battery for receiver and servo)
Glow, gas or electric powered aircraft using separate a receiver battery supply
Follow below connection diagram when using a regulated Li-PO, Li-Fe (2cell) or 4~6cell Ni-MH, Ni-CD battery.
ID Link (ID-Set up)
Each radio set (using Spectra G3 system and SRX 12 or MRX 3 receiver) is already Linked from the factory. You
don’t need to ID Link when you purchased a set of radio. However, If you buy additional SRX 12 or MRX 3
receiver, you have to do ID Link with new receiver and the radio. Before ID Link, please make sure all connection
correctly refer to above connection diagram.
How to ID Link between G3 Spectra radio and SRX 12/MRX 3 receiver
1)
Turn on the Radio power
2)
Select ‘Spectra’ in the system menu in the radio. (Aurora 16/Flash 14)
3)
Select G3 and choose Frame Time
Receiver No (S1)
Bus type step by step.
4)
Make sure distance between radio and receiver within 3 feet and turn on Receiver power.
5)
Blue LED in the receiver will be blinking rapidly and will be blinking slowly.
6)
Please check ID Link correctly or not by moving radio stick and press ‘Finish’ in the menu to escape.
Fail-Safe / Hold Function Mode
Fail-Safe Mode?
-
If the receiver signal somehow becomes interrupted or interference occurs, the servos will move to the
pre-set Fail-Safe point you previously stored in the Fail-Safe set-up. Make sure you set the Fail-Safe
function properly.
If Fail-Safe has not been activated, the signal will switch off after the Hold period of one second. This
means that the servos become “soft” and remain in their last commanded position under no load (this
may equate to full-throttle!), until a valid signal is picked up again.
-
In the interest of safety, we recommend that the Fail-Safe function should always be activated, and the
Fail-Safe settings should be selected so as to bring the model to a non-critical situation (e.g. motor idle
/electric motor OFF, control surfaces neutral, airbrakes extended, aero-tow release open, etc.).
1) Switch on the Radio
2) Select ‘Fail-Safe’ from system menu in Aurora 16/Flash 14
3) Select Fail-Safe or Hold for your purpose
4) If you choose ‘Fail-Safe’, set the Fail-Safe position of servo or motor by change value in the menu or stick
and then press ‘Set’ to confirm.
5) Press ‘Send’ to memorize Fail-Safe value to Receiver. (LED in the receiver will be blinking rapidly)
