LINK PROCEDURE
Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with
the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and no
further linking is necessary unless the receiver is to be used with another transmitter. (For T/R set, the link is already done
at the factory.) When you purchase another R2004GF, this procedure is necessary; otherwise the receiver will not operate
properly.
ｎWARNING
ｊ
After the linking is done, please cycle receiver power
and check if the receiver to be linked is really under the
control by the transmitter to be linked.
ｌ
Do not perform the linking procedure with motor's main
wire connected or with the engine operating as it may
result in serious injury.

1. Place the transmitter and the receiver close to each other
within one (1) meter
2. Turn on the transmitter.
3. Turn on the receiver.
4. Push and hold the Link switch on the receiver.
5. When the link is complete, the LED on the receiver
changes to solid green.
* Please refer to the table below for LED status and receiver
condition.
No signal reception
Red : On
Receiving signals
Green: On
Receiving signals, but ID is unmatched.
Green: Blink
* If there are many FHSS 4YF 2.4GHz systems turned on around
your receiver, it might not link to your transmitter. In this case, even
if the receiver’s LED stays solid green, unfortunately the receiver
might have established a link to one of the other transmitters. This
is very dangerous if you do not notice this situation. In order to
avoid the problem, we strongly recommend you to double-check
whether your receiver is controlled by your transmitter by giving
stick input and then checking servo response.
ｎWARNING
ｌ
NEVER use dry batteries for R2004GF as it may cause difficulties.
