Installation
For electric powered modelsInstalling the Antenna
Please keep distance to the receiver site,
due to noise sources of the battery, motor,
ESC, etc. If possible. Also keep away power
c o n d e n s e r s a n d s h o t k i d i o d e s t h a t
generate noise from the receiver antenna if
possible.
●Please use plastic mounts and a plastic antenna tube. Please keep the antenna wire elevated to the
highest position available.
●Please do not use a metal antenna mount because it will create problems.
●To protect the main antenna, insert the antenna into the antenna tube.
●Please do not disconnect or cut the antenna. This will cause loss of signal.
●Please do not disconnect or cut the antenna wire. You will receive less range.
●Please place antenna away from receiver battery, ESC, motor and silicon wires and any
other noise source. The antenna wire for the receiver requires special attention.
ATTENTION
Compatibility with conventional models
When changing your conventional receiver to the RF-903FH / RF-904FH
module / KR-411FH receiver, please note the following.
●Check the operating range of each channel and re-adjust the travel,
steering, throttle high point and brake points on your transmitter.
●For electric cars, ESC (speed controller) should also be reset to your
transmitter.
If you use it without checking these setting, the servo may
become damaged or may cause abnormal behavior.
ATTENTION
Pairing
When using the receiver for the first time, the receiver must store the ID number
of the module and “pairing” of the receiver and module is necessary. Pairing
must be performed when the module that is used is modified. When multiple
receivers are used, each receiver must go through the pairing process at least
once. This product has a French mode that respects the French 2.4GHz rule.
Please use this mode in France.
●If the pairing fails it may be due to a wireless LAN, microwave
oven or someone else trying to pair at the same time. Please
move to another location where you can try the pairing again.
●After pairing is completed, turn on the transmitter and then the
receiver and your system will be ready to use.
ATTENTION
Prepare the module for
the pair process. Please

Functions
Fail-safe function
D.S.C. (Direct Servo Control)
By connecting receiver and servo directly with transmitter using D.S.C. (Direct Servo Control), you can configure settings without transmitting radio wave in pit
area or near R/C circuit. Please read the instruction manual of the transmitter.
Fail-safe is when the receiver loses the radio signal of the transmitter and the function keeps channel 2 (throttle) in an optional position.
The configuration is usually full brake or neutral.
Please be sure to set the fail-safe.
WARNING
If you change the position of the fail-safe
o p e r a t i o n , p l e a s e s e t a g a i n . W e
recomme nd to set it again even if you
modify the car engine brake linkage.
ATTENTION
This function works for
only 2nd channel.
