CORONA RP4S1 Quick Start Manual

Receiver RP4S1
Thank you for purchasing the world's smallest
synthesized receiver! Please read the manual
carefully before using the receiver.
Why Synthesized Receiver?
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.
RP4S1's Feature
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 RS410II 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.

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.
Quick Range Checking
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.
Rigorous Range Checking
Your local environment can affect the range of
the 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.
Use method
I．Normal Working State:
Turn on transmitter and adjust it to PPM
mode. When electrify the receiver, the LED will
blink 2 times. Then if it receives correct signal,
the LED will be lightening and work normally; if
LED went out, it means the transmitter do not
receive correct signal.
Note: 1 This receiver has the feature of
memory, please electrify the receiver again if
change another transmitter.
2 When change crystal of different
frequency, please lock up new transmitting
frequency.
