ECEIVER CONNECTIONS
The RX-7-SYNTH IPD, RX-7-SYNTH DS IPD and RX-9-SYNTH
DS IPD compact receivers are fitted with universal UNI sockets
which are compatible with the plugs used by most radio control
manufacturers (HiTEC, robbe / Futaba, Graupner / JR, ...).

! Check plug polarity carefully when connecting the
receiver battery, servos, speed controllers etc. Check
the pin configuration, especially with other brands of de-
vice (see pin assignment symbol on the receiver

UPPLY
The receivers work 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 ... 7 (9), see also (
! Check the maximum permissible operating voltage of all
devices connected to the receiver (servos, etc.)!
For example, some servos are only approved for use with 4 cells
(4.8 V).
! Note:
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 connec-
tors, or from overloading or faults in the BEC system.

SING THE RECEIVER
The receivers are 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 store 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.

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
