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

OWER UPPLY
The RX-7 SYNTH IPD and RX-7 SYNTH DS IPD receivers work over a
broad voltage range of 3.5 — 7.5 V (
battery).
The receiver battery can be connected to the socket marked "B/D", to
any vacant servo socket "1" ... "7", and / or to the "AUX" socket.
! 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 maintained 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, or from overloading or faults
in the BEC system.

SING THE RECEIVER
The RX-7 SYNTH IPD and RX-7 SYNTH DS IPD 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 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 corresponding 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 LED flashes during the
RF channel search:
1,6 sec
LED Code 2
(
Setting the RF channel
Note:
The receiver checks the operating voltage: the value must be above 4.5 V
immediately after it is switched on. If not, the receiver 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 CHANNEL
With the RX-7 SYNTH IPD and RX-7 SYNTH DS IPD receivers the RF chan-
nel 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:
The RF channel search generally takes about 2 - 4 seconds. If the
process takes significantly longer, this indicates that no clear trans-
mitter signal is present. Check that your transmitter 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 cor-
rect RF channel.
The process is complete when the LED flashes the confirmation sig-
nal:
1,6 sec
LED Code 5
4. The receiver must now be switched off, then on again (
now be operating on the set RF channel.
The receiver stores the set RF channel permanently until either you set a
new RF channel, or RESET the receiver to the factory default settings
( 15. ).
Note:
The signal output to the servo outputs remains switched off during the
RF channel search process, i.e. the servos do not move and are "soft", and
(modern) electronic speed controllers stay OFF, because the signal is
absent. Nevertheless, it makes sense to secure the model and keep well
clear of hazardous parts.
