1. Synthesized receiver gets rid of the inconvenience of
using the crystal. Receivers with crystal still use the
technology of 1970 ’ s which have to switch the
frequency by changing the crystal. Users have to
bring dozens of crystal to flying field. In addition,
every changing of the crystal may damage the
electron devices. While it is only need to push the
button, you can switch to any channel with
synthesized receiver.
2. Every transmitter and receiver has production
tolerance inevitably. But the production tolerance of
the crystal affects it most. Even the most precise
crystal has the tolerance of 1 - 2KHz, and sometimes
it will be 4KHz. This is a big tolerance to a 10KHz
narrow receiver. Synthesized receiver will correct
the tolerance because it can automatically follow
the frequency tolerance. It is what will make R/C
receiver has the best performance.
With Corona ’ s technology in manufacturing R/C products,
RP4S14 4CH Single conversion receiver becomes the
smallest in the world. Do not only focus on its small size.
Its high - performance will surprise you.

1. You can switch the frequency freely.
2. It can automatically follow the frequency tolerance
which will make it compatible with all transmitters,
including the high - rate transmitter.
3. The 'one - button' function makes it convenient to
change the frequency.
4. With such a small size, the receive range reaches as
far as 1 mile +!
5. The dual ceramic IF filters ensure ultra narrow
selectivity, and can reject the adjacent channel
interference effectively.
6. DSP technology can filter the noise intelligently and
eliminate glitch effectively.
You can put R P4S1 receiver in any place when you
install it on whatever electric puddle - plane, 3D plane,
glider or training plane. And don't worry the trouble
which will be brought by changing CG.
Reliability, high performance and sale price, they are
what CORONA can provide for you.

1.Turn the transmitter power on ,adjust the mode to PPM and
make sure the transmitting frequency be in the frequency list
2.get the receiver close to the transmitter, then connect it to
the battery
3.after the LED in receiver flashing two times, press the button
for two second, then release the button ,then press the button
again ,LED will begin to flash, when the LED stops flashing , it
suggest that the receiver can work now.
4.after the receiver locked, if you don ’ t change frequency,
receiver will work when you connect it to the power. no need
to relock.
5．If you change different transmit brands but not change
frequency ,you just cut off receiver power and connect it to the
battery again , then the receiver will works well.
Caution: when you locking your receiver, please ensure around
5 meters only your own transmitter is working and put your
receiver close enough to your transmitter.

Fully collapse the transmitter ’ s antenna and move the
transmitter sticks continuously. Ask someone to watch
the servos to see whether the receiver has lost the signal.
If the receiver does not lose the signal until you are at
least 90m away from it, it passes the quick range check.

receiver, so quick range checking may not reflect the
actual range correctly. If you suspect range problems,
perform a rigorous range check.
1. Place the receiver on a non - metallic surface (for
example, a wooden bench) which is at least 2 feet
(60cm) off the ground.
2. Fully extend the antenna of the receiver and fix it
vertically. Don ’ t let it touch the ground.
3. Connect one servo to channel 1.
4. Fully extend the antenna of the transmitter.
5. Turn on the transmitter and then turn on the
receiver.
6. Walk away from the receiver while moving the
transmitter sticks continuously. Ask someone watch
the servo and note any loss of control.
