A low-voltage power-on guard prevents the receiver operating if
switched on with a voltage below 4.5 V. Once operating, the receiver
works without problem down to a voltage of 3.5 V.
2. SAFETY NOTES
! Read the instructions before using the receiver for the first time
! Use the receiver for its intended application only (Î 4.)
! Be sure to use a power supply of adequate capacity (Î 8.)
! Read and observe the installation notes (Î 22.)
! Carry out regular range checks (Î 23.)
! 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
MULTIPLEX RX-SYNTH receivers can also be operated in conjunc-
tion with transmitters not exploiting Synthesizer technology, i.e.
those using conventional plug-in crystals. Synthesizer technology
simply provides a modern, convenient, extremely flexible and
highly accurate method of generating a frequency.
All MULTIPLEX RX-SYNTH IPD receivers work on the basis of the FM /
PPM transmission process, which is compatible with most other
makes of RC equipment. This means that mixed operation with
FM/PPM transmitters of other makes is possible in principle.
However, we cannot guarantee that such a system will work
perfectly, as there are too many possible combinations for us to
check.
3. SPECIAL FEATURES
x PLL synthesizer receivers, requiring no plug-in crystals.
x Quick, simple change of RF channel using automatic channel search,
with Lock-on security by confirmed channel acceptance from the
transmitter.
x Use of standardised FM/PPM transmission format ensures compati-
bility with other makes of equipment
x IPD decoder (Intelligent Pulse Decoding) with HOLD and FAIL-SAFE
functions
x Error counter
4. INTENDED APPLICATION
The RX-7 SYNTH IPD and RX-7 SYNTH DS IPD receivers are designed
exclusively for use as radio control receivers for model sport applications.
Their use in man-carrying vehicles or industrial apparatus is prohibited.
5. CE CONFORMITY DECLARATION
MULTIPLEX Modellsport GmbH & Co.KG declares that these devices
fulfil the requirements of the following harmonised directives of the
European Union (EU):
x Protection requirements concerning electro-magnetic compati-
bility
EN301 489
x Measures for the efficient use of the radio frequency spectrum
EN300 220
6. QUICK START
1. Switch the transmitter on.
2. Connect the receiver battery to the receiver and switch on.
 LED flashes (RF channel search):
LED Code 2
1,6 sec
The RF channel search is concluded when the LED glows constantly:
LED Code 1
LED ON
3. Move any transmitter stick four times steadily to one end-point.
 the LED must switch OFF / ON in time with the stick movement.
4. The RF channel setting procedure is concluded; the LED flashes:
1,6 sec
LED Code 5
5. Switch the receiver OFF, then ON again.
 The receiver is ready for use; the LED flashes:
