Operating tempera-
ture range
5°F … 130°F or -15°C … 55°C

! Read the instructions before using the receiver for the first time
! Carry out regular range checks (Î 15.)
! Keep strictly to the following sequence when switching
on and off:
First switch the transmitter ON, then switch the receiver ON
First switch the receiver OFF, then switch the transmitter OFF
! Note regarding mixed operation
This receiver can also be operated with transmitters not using Synthe-
sizer technology, i.e. those using conventional plug-in crystals. This re-
ceiver is compatible with most other makes of RC equipment. Mixed
operation with FM/PPM transmitters of other makes is possible in prin-
ciple. However, we cannot guarantee that such a system will work per-
fectly, as there are too many possible combinations for us to check.

• PLL synthesizer receiver, requiring no plug-in crystals.
• Quick, simple change of RF channel using automatic channel search,
with Lock-on security by confirmed channel acceptance from the trans-
mitter.
• Dual shift (automatic shift switching) Use any FM transmitter.
• Use of standardised FM/PPM transmission format ensures compatibil-
ity with other makes of equipment
• IPD decoder (Intelligent Pulse Decoding) with HOLD and FAIL-SAFE
functions

ECEIVER CONNECTIONS
The FUSION 9 receiver is fitted with universal UNI sockets which are
compatible with the plugs used by most radio control manufacturers (Hitec,
Futaba, JR, …).
Socket Function
B Socket for receiver battery
1 - 9 Servo sockets, channels 1 … 9
! Check plug polarity carefully when connecting the receiver battery,
servos, speed controllers etc. Check the pin configuration, espe-
cially with other brands of device.
(see pin assignment symbol on the receiver )

UPPLY
The FUSION 9 receiver works over a broad voltage range of 3.5 – 7.5 V
(
Æ 4 – 5 cell NiCd or NiMH receiver battery).
The receiver battery can be connected to the socket marked “B”, or to any
vacant servo socket 1 … 9 (see also
Î 5.).
!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).
A battery in good condition and of adequate capacity for the purpose is
indispensable for the safe operation of any model:
• Cables should be of adequate conductor cross-section. Keep all leads
as short as possible, and avoid unnecessary connectors.
• 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 connectors, or from overloading or faults in
the BEC system.

/ LED
INDICATORS
The FUSION 9 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 store the FAIL-SAFE posi-
tions
• To switch off the IPD filter (e.g. for range checks)
• 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
( Æ IPD filter active Î 10. ). 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:
LED Code 2
1,6 sec
( Æ Setting the RF channel Î 9. )
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
RF
CHANNEL
With the FUSION 9 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 receivers SET button pressed in,
Switch the receiver on,
Release the SET button.
Æ The RF channel search commences; the LED flashes:
LED Code 2
1,6 sec
Note:
The RF channel search generally takes about 2 - 4 seconds. If the
process takes significantly longer, this indicates that no clear transmit-
ter 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 correct
RF channel.
The process is complete when the LED flashes the confirmation signal:
1,6 sec
LED Code 5
4. The SET button must now be pressed and the receiver will 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 (
Î
13. ).
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.
