ButtonLEDChannel & Battery PortAntenna1. The receiver antenna should not be placed near the engine, metal parts, or high current batteries.2. The receiver Antenna should not get damaged. To prevent antenna damage, do not install the antenna near the sharp edge or bend it more than 90 degree in angle.3. Use a Velcro or think double sided tape to install to absolve the shock during the operation.4. When LED indicator irregularly blinks, indicates unstable frequency environment, stop operating and look for the possible cause of problems.LEDFunc.

What is Fail-Safe Mode?If you use the FAIL-SAFE function, and set it up properly, should the receiver signal somehow be interrupted or interference were to occurred, the servos will move to your pre-set FAIL-SAFE position you previously stored in the receiver during the FAIL-SAFE set-up. If FAIL-SAFE has not been activated, the signal is switched off after the HOLD period of 1 sec. 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 interests of safety, we recommend that FAIL-SAFE 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, or full brake, etc.)When LED On (Fail-Safe Mode On): Press the function button once to switch to the hold mode, the LED will goes off and indicates that the receiver is in Hold Mode.Note: once you switch to the hold mode all the saved Fail-Safe position will be deleted.When LED Off (Hold Mode On): To switch to the Fail-Safe Molde, first adjust all the control knobs to the fail-safe position you prefer, then press the function button once, the LED turns on at the same time the fail-safe position will be saved. Once Fail-Safe/Hold Selection Mode activated , you can keep switching the mode by pressing the function button.
