for 4 cell and 5.7V for 5 cell for Ni-Cd or Ni-MH batteries

5. RECEIVER CONNECTIONS

The HSD-09RQ (FREEDOM 9S) receiver is fitted with universal UNI sockets which

are compatible with the plugs used by most radio control manufacturers (Hitec,

Futaba, JR, etc.).

6. POWER SUPPLY

The HSD-09RQ(Freedom 9S) receiver works with 7.4V (2 cell) Li-Po batteries or

over a broad voltage range of 4.8V - 8.4V (4 - 5 cell) Ni-CD or Ni-MH receiver batteries

The receiver battery can be connected to the socket marked “CH9/BATT”, or to any

vacant servo socket 1 … 8 (see 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.

7. USING THE RECEIVER / LED INDICATORS

The HSD-09RQ (FREEDOM 9S) receiver is fitted with one LED and one button (SET).

These are used as follows:

• To set the RF channel

• To indicate low battery warning

• To activate the FAIL-SAFE function and store the FAIL-SAFE positions

• The various operational states are indicated by the LED. The following

section describes the receiver settings and corresponding LED CODES.

The effect of FAIL-SAFE: When interference occurs the servos take up a

pre-determined position, previously stored in the receiver. If FAIL-SAFE has

not been activated the signal is switched off after the HOLD period (1 sec.).

This means that the servos become “soft” and remain in their last commanded

position under no load (this may equate to full-throttle!) until a valid signal is

picked up again.

! Note:

In the interests of safety we recommend that FAIL-SAFE should always be activated,

and the FAIL-SAFE settings should be selected so as to bring the model to a

non-critical situation (e.g. motor idle / electric motor OFF, control surfaces neutral,

airbrakes extended, aero-tow release open, …).

10. ACTIVATING FAIL-SAFE

1. Switch on the transmitter, then the receiver. The LED glows constantly:

1. HSD-09RQ (FREEDOM 9S) will recognize a battery type automatically between

4 cell and 5 cell

2. When battery level is high (4 cell: >4.6V, 5 cell: >5.7V): LED glows constantly

LED Code 1

3. When battery level is low (4 cell:<4.6V, 5 cell:< 5.7V): LED will blink

Sequence

11. LOW BATTERY WARNING

12. INSTALLATION NOTES

• You should pack your receiver loosely in foam or similar material to protect it from

vibration - especially with internal combustion motors.

• Install the receiver at least 6” away from electric motors, ignition systems and other

electronic components. The receiver aerial should not run immediately next to these

components.

• Brushed electric motors must be effectively suppressed.

• Use separation filters if you are using servo extension leads longer than 24”.

• Do not alter the length of the aerial.

• Route the aerial out of the model and extend it in as straight a line as possible.

Do not leave it coiled up.

• Do not deploy the receiver aerial parallel to servo leads, high-current cables or

electrically conductive components (e.g. pushrods).

• Do not deploy the aerial inside or over model components which are skinned or

reinforced with conductive materials (e.g. carbon fibre, metallic paints etc.),

as they have a shielding effect.

13. CARRYING OUT A RANGE CHECK

It is very important to carry out regular range checks to ensure that the

radio control system works reliably. These checks also allow you to detect

problems and sources of interference in good time. This applies in

particular when:

• you are using new or altered components, or you have changed the

arrangement of components in the model;

• you are using radio control system components which were involved in

a previous hard landing or crash;

• irregularities or problems have arisen during previous flights.

! Important:

• For a range check install the telescopic transmitter aerial but leave it

completely collapsed.

• The range of the HSD-09RQ(FREEDOM 9S) receiver with transmitter aerial

collapsed down to a single segment should be at least 150’.

• You have reached the range limit when the servos begin to jitter and move

uncontrollably.

! Important:

Carry out the initial range check with the motor or engine stopped. Repeat

the check with the power system operating (all throttle settings): the range

should not be significantly reduced. If it is much lower, seek out and

eliminate the cause of the problem (motor interference, arrangement of the

receiving system components and power supply, vibration, etc.).

LED CODES

8. SWITCHING ON

1. If you have already set the receiver to an RF channel, the LED glows constantly to

indicate HOLD mode on.

9. Auto Shift switching (FREEDOM 9S only)

The FREEDOM 9S receiver can be operated with Positive Shift (e.g. JR,

AIRTRONICS, MULTIPLEX) and Negative Shift (e.g. HiTEC, Futaba). The

receiver automatically sets itself to the appropriate shift while setting the

channel. If you wish to use a transmitter with different shift, you must re-set

the RF channel.

! 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 )

2. SAFETY NOTES

! Read the instructions before using the receiver for the first time

! Use the receiver for its intended application only

The HSD-09RQ/FREEDOM 9S receiver is designed exclusively for use as a

radio control receiver for model sport applications. Its use in man-carrying vehicles or

industrial apparatus is prohibited.

! Carry out regular range checks (see 13.)

! 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 Synthesizer technology,

i.e. those using

conventional plug-in crystals. This receiver is compatible with most other makes of

RC equipment.

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.

2. Press and hold the button for three sec then LED will turn off to indicate

FAIL-SAFE ON Also, FAILSAFE SETTING MODE ON

LED Code 0

3. Move all the transmitter sticks and other controls to the desired FAIL-SAFE positions

(e.g. motor idle, control surfaces neutral).

4. Press the button once (approx. 0.5 seconds); the LED goes out.

⇒ FAIL-SAFE is now active, and the FAIL-SAFE positions are stored.

! Note:

• If you hold the button pressed for more than 6 seconds; LED will blinks three times

then steady on to indicate FAILSAFE OFF.

• In this case FAIL-SAFE is not activated, and the FAIL-SAFE settings are not stored!

5. Testing the FAIL-SAFE settings

Move the sticks to positions other than the FAIL-SAFE settings, then switch off the

transmitter. The servos should now move to the FAIL- SAFE settings previously stored,

once the HOLD period (1 sec.) has elapsed.

! Note:

• The FAIL-SAFE settings must always be checked and brought up to

date if, for example, you install the receiver in a new model, or make

an accidental mistake in programming the receiver.

! Note: Low Battery Warning function is available for the Ni-Cd

and Ni-MH batteries only.

LED Code 6

3. 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:

! 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 happens, the LED lights up briefly.
