ECEIVER CONNECTIONS
The RX RX-5 SYNTH IPD CAR receiver is fitted with universal
UNI sockets which are compatible with the plugs used by most
radio control manufacturers (HiTEC, robbe / Futaba, Graupner /
JR, ...).
Socket Assignment / Function
B/D Receiver battery, diagnosis lead or PC lead
1, 2, 3, 4, 5 Servo sockets, channels 1 ... 5
! Check plug polarity carefully when connecting the
receiver battery, servos, speed controllers etc. Check
the pin configuration, especially with other brands of
device (see pin assignment symbol on the receiver:
).

OWER UPPLY
The RX-5 SYNTH IPD CAR receiver works over a broad voltage
range of 3.5 – 7.5 V ( 4–5 cell NiCd or NiMH receiver battery).
The receiver battery can be connected to the socket marked
"B/D", or to any vacant servo socket "1" ... "5" (
! Check the maximum permissible operating voltage of all
devices connected to the receiver (servos, etc.)!
Please note that many servos are only approved for use with
four NiXX cells (4.8 V).
! Note: power supply / battery system
A power supply (battery system) in good condition and of
adequate capacity for the purpose is indispensable for the safe
operation of any model:
Use only high-quality receiver batteries of adequate capacity.
The cells should be balanced, and the pack properly main-
tained and charged
Cables should be of adequate conductor cross-section. Keep
all leads as short as possible, and avoid unnecessary
connectors
Use high-quality switch harnesses exclusively
If the system voltage falls below 3.5 V the receiving system
may fail to work properly. Such voltage collapses may occur
due to flat, poor-quality or defective receiver batteries, cable
conductors of inadequate cross-section, poor-quality con-
nectors, or from overloading or faults in the BEC system

SING THE RECEIVER
The RX-5 SYNTH IPD CAR receiver is fitted with one LED and
one button (SET). These are used as follows:
To set the RF channel
To activate the FAIL-SAFE function and set the FAIL-SAFE
positions
To switch off the IPD filter (e.g. for range checks)
To display the error count
To reset the receiver to the factory default settings (RESET)
The various operational states are indicated by the LED. The
following section describes the receiver settings and correspon-
ding LED CODES.

INDICATORS

WITCHING ON
If you have already set the receiver to an RF channel, the LED
flashes after you switch it on:
1,6 sec
LED Code 3
( IPD filter active 12.). The receiver is ready for use
If the receiver picks up an invalid signal, or no signal at all, when
it is switched on, the LED glows constantly until a valid signal is
received:
LED Code 1 LED ON
If you have not yet set an RF channel (new receiver, or after a
RESET), the RF channel search commences automatically. The
LED flashes during the RF channel search:
1,6 sec
LED Code 2
( Setting the RF channel
! Note: checking the operating voltage
The receiver checks the operating voltage: the value must be
above 4.5 V immediately after it is switched on. If not, the re-
ceiver will not work until the voltage rises to a value above 4.8 V.
If this should happen, the LED lights up briefly, then stays off
until an operating voltage of more than 4.8 V is present:
LED Code 0 LED OFF

ETTING THE
With the RX-5 SYNTH IPD CAR receiver the RF channel is set
by means of an RF channel search, during which the receiver
searches for the most powerful transmitter on the band. For this
reason it is essential that your transmitter, set to the desired RF
channel, should be in the immediate vicinity of the model
(receiver) during the RF channel search. During the RF channel
search keep the receiver a reasonable distance (> approx. 3 m)
from other transmitters which are switched on.
Sequence:
1. Switch ON the transmitter, already set to the desired RF
channel,
Hold the receiver button pressed in,
Switch the receiver ON,
Release the button
The RF channel search commences; the LED flashes:
1,6 sec
LED Code 2
! Note: duration of the RF channel search
The RF channel search generally takes about 2 - 4 seconds.
If the process takes significantly longer, this indicates that no
clear transmitter signal is present. Check that your trans-
mitter is switched ON, and that no other transmitter is in the
immediate vicinity. Repeat Step 1.
2. The LED glows continuously when a transmitter is located:
LED Code 1 LED ON
3. Now move one transmitter stick four times steadily to the
same end-point. The LED should go OFF in time with the
stick movement. This is your means of checking that the
receiver has locked onto the correct RF channel
The process is complete when the LED flashes the
confirmation signal:
