Sanwa RX-391W Operating Instructions

Thank you for purchasing the SANWA RX-391W 2.4GHz FHSS-E 3-Channel Micro receiver. This receiver can be
used with SANWA 2.4GHz FHSS-E surface transmitter, such as the MX-6 FHSS-E. Please read through
these Operating Instructions entirely before installing and using your new receiver.
Due to differences in the implementation of 2.4GHz technology among different manufacturers, this
receiver is compatible only with SANWA brand 2.4GHz surface transmitters.
Model: RX-391W
Frequency: 2.4GHz FHSS-E
Input Voltage: 4.8v ~ 7.4v
Weight: 12.4g
Dimensions: 24.0 x 37.0 x 18.2 mm
Fail Safe Support: Yes - Throttle
2.4GHZ FREQUENCY BAND PRECAUTIONS
This receiver operates on the 2.4GHz frequency band. The 2.4GHz connection is determined by the transmitter
●
and receiver pair. Unlike ordinary crystal-based systems, your model can be used without frequency control.
● The 2.4GHz frequency band may be used by other devices, or other devices in the immediate area may cause
interference on the same frequency band. Always before use, conduct a bench test to ensure that the servos
operate properly. Also, conduct checks with the transmitter as distant as possible from your model.
The response speed of the receiver can be affected if used where multiple 2.4GHz radio controllers are being
●
used, therefore, carefully check the area before use. Also, if response seems slow during use, stop your model
immediately and discontinue use.
If the 2.4GHz frequency band is saturated (too many radio controllers on at once), as a safety precaution,
●
the radio control system may not bind. This ensures that your radio control system does not get hit by
interference. Once the frequencies have been cleared, or the saturation level has dropped, your radio control
system should be able to bind without any problems.
RECEIVER CONNECTIONS AND MOUNTING
Use the diagram below to make the connections to the RX-391W 3-Channel 2.4GHz FHSS-E receiver included with your MX-6 3Channel
2.4GHz FHSS-E radio control system.
The receiver`s Nominal Input Voltage is 4.8~7.4 volts. A2 cell Li-Po or 2 cell Li-Fe battery pack can be used to power the receiver
without the use of a voltage regulator. In addition, this allows you to take advantage of the higher torque and speed provided by using
7.4 volt digital servos.
Use a 2 cell Li-Po or 2 cell Li-Fe battery pack ONLY if your servos are rated to handle the higher voltage.
If you`re using an Electronic Speed Control with BEC circuitry, verify that it reduces the voltage to between 4.8 and 7.4 volts before
making your connections and turning your radio control system ON.
・We suggest binding the transmitter and receiver and making all receiver connections to check for correct operation prior to mounting the
receiver in your model.
・The receiver should be mounted as far away from any electrical components as possible.
・Route the receiver antenna up through a plastic tube so that it is in the vertical position.
・To protect the receiver from vibration and other damage. we recommend wrapping the receiver in shock absorbing foam or using
double-sided foam tape when installing it in your model.
As a safety precaution, set your model on a stand so the wheels are off the ground before turning on your radio control system or
connecting your motor for the first time.
