- A three-pin servo connector port is featured on the Spectra 2.4GHz module allowing you to upgrade the
device software as well as download any information recorded when using Hitec's AFHSS 2.4GHz optional
on-board sensors. This port also interfaces with our new Telemetry System Sensor Station, allowing real-time
data display on the ground when ying with the Aurora 9 transmitter.
4. Adjustable Omnidirectional Antenna
- The Spectra 2.4GHz antenna is an omnidirectional antenna which can transmit and receive the transmitter
and receiver data.
For the best reception, refer to the set-up example picture in the above Warning box.
5. Compatible Transmitters
- The Spectra 2.4GHz module and antenna can be used with the following Hitec transmitters:
Eclipse 7, Optic 6, Aurora 9 and all future Hitec module-type transmitters.
- In all cases, any transmitter using the Spectra 2.4GHz module will be compatible only with
Hitec AFHSS 2.4GHz series receivers.
General Use Guidelines
To turn the system on and o, use the following sequence at all times.
Before each ight, it is critical that you perform a range check to conrm the signal between the receiver and
transmitter is appropriate. Unlike the FM/PPM or PCM signal radios, 2.4GHz systems use a xed, shorter
transmitter antenna commonly called a "rubber duck" antenna. Therefore, the traditional method of range
check, lowering the transmitter antenna, is not applicable.
The Hitec 2.4GHz system uses a“power down”mode to reduce the transmitter signal strength.
Once the“power down” mode is activated, it runs for about 90 seconds eectively shortening the range to 30
meters or 100 feet. During this "power down" mode, you should walk away from the secured aircraft carrying the
transmitter to a minimum distance of approximately 30 meters or 100 feet in order to test the eective range.

Spectra 2.4 Module Features
- Installing Spectra 2.4J module to your JR* transmitter is as easy
as one, two, three. simply slide the module through the carrying
handle bar and slide-in the module to the module slot of the
transmitter, until you hear the‘click’ sound. Turn the power
on of the transmitter and the receiver, wait until the
Spectra 2.4J moudle and Optima receiver get connected.
Warning!
1. For maximum performance, we recommend positioning the antenna at a 90 degree
angle as shown below.
*JR is a registered trademark of Japan Remote Control Corporation of Japan
2. The receiver antenna should not be placed near
the engine, metal parts or high current batteries.
3. When using a large number of high-power digital
servos, we recommend using the SPC feature to
insure the receiver gets the power it needs in
high-load conditions.
4. Depending on ying conditions, you may possibly
experience a time delay in receiving telemetry
data from the HTS-SS (Sensor Station).
Recommended Position
* Above image is dierent than the actual transmitter used. JR* transmitter is required to work this module properly.
With the exception of the Aurora 9 and future Hitec 2.4GHz models, all other transmitter
modules should be set up as PPM.

Link Guidelines
Link (ID-Setting)
Scan and Normal Mode Information
Warning
- When both red and blue LEDs are "on" and both module and receiver are powered up and bound
together, the Scan Mode is active. Two beeps will be heard when the system is turned on.
- When the red LED is "on"and both module and receiver are powered up and bound together,
the Normal Mode is active. Four quick beeps will be heard when the system is on.
Your Hitec AFHSS 2.4GHz system uses a communication protocol that links and binds the Optima receiver to
your transmitter. Once the receiver and module are“bound,” no other transmitter can interfere with your
receiver during its operation. In the case of multiple model memory transmitters, you can bind as many
Optima receivers to your transmitter as necessary, one per model memory.
Each module and receiver set is paired at the factory in Normal Mode for your convenience. To change the
transmitter to Scan Mode see page 2 (Scan and Normal Mode Information).
- Before each ying session to conrm the radio system is working properly.
- Before the engine or motor is started, turn on the system as explained above.
Then make sure all the servos and control surfaces are working properly.
If any control surface is not moving properly, do not y the aircraft until the problem is solved.
- If you are unable to accomplish a successful range check of 30 meters(100 feet),
DO NOT ATTEMPT TO FLY.
Note
Too Close: Less than 50Cm(18in)
Too Far: More than 5M(15ft)
Hitec’s Spectra AFHSS 2.4GHz systems can be operated with two dierent modes : Normal Mode or Scan Mode.
Each mode selection can be controlled only from the Spectra 2.4GHz module; however, you can view the
current system status from the receivers.

Module Receiver
Telemetry System
The Hitec Spectra 2.4GHz module and Optima series receivers feature full telemetry capabilities (except for the
Optima 6) and include a Low Receiver Battery Warning as a basic function.
I. Basic Function: Low On-board Battery Warning - for All Optima Receivers
- When the Optima series receiver is powered up, it will automatically detect the battery voltage level and
recognize between 4-cell or 5-cell NiMH and NiCd batteries (4-cell < 5.8V <5-cell).
If a 2-cell LiPo battery is being used, you can customize the battery warning level by using our HPP-22
program.
- When battery level is safe (4-cell > 4.5V, 5-cell > 5.6V), no changes will appear to the LED lights.
- When battery level is low (4-cell < 4.5V, 5-cell < 5.6V), the blue LED glows constantly and the red LED blinks
fast. Three continuous beeps from the module serve as a low receiver battery warning. Upon hearing the
alarm, we advise you to land at once.
II. Optional Functions: GPS, FUEL, TEMP, O-RPM, M-RPM Sensors - Applicable for Optima 7 & 9 Only
- More devices will be available in the future. Check the Hitec website at www.hitecrcd.com for more
up-to-date informatio
- Low Battery Warning function is only for reference. The actual battery level may dier.
Be aware that lazy battery eect or battery memory eects could impact the Low Battery
Warning function from operating properly.
- When 2.4GHz system and HV servos are used together, we strongly recommend using a large
capacity battery pack in a fully charged condition. You must constantly monitor the battery status.

- Link must be established within 15 feet of the transmitter and receiver.
- Transmitter and receiver need to be at least 18 inches from each other to link properly.
- In the Scan Mode, if the transmitter or receiver has been shut o or disconnected
for more than one second, both module and receiver need to be rebooted (turn the
power o and back on).

HTS-GPS (GPS Sensor)
HTS-FUEL (Fuel Level Sensor)
This fuel level sensor indicates ve steps of fuel level (Full, 3/4, 1/2, 1/4, Empty) to the
yer. Installation is easy, simply stick the sensor outside of the fuel tank and y. It can
even read the values during inverted ight
Power-up the system prior to fueling.
- During extreme 3D ight, the reading can be inaccurate, if this happens try to hover
(for Heli), and atten out (for Acro) for a few seconds to re-establish an accurate reading.
The fuel sensor is only made to be used with glow fuel.
HTS-MRPM (RPM Sensor)
HTS-TEMP (Temperature Sensor)
HTS-SS can measure up to four dierent temperature locations, using the HTS-TEMPs,
the temperature sensors. These specially designed temperature sensors are wrapped
with high temp resistant shrink tubing and can read temperatures
from -40°C to 200°C (-40°F to 392°F).
These sensors can be used almost anywhere.
M-RPM sensor has been developed for indoor aircraft and for applications where the
O-RPM sensor is too big to be installed. Furthermore, it will give you a much more
accurate reading. For optimum performance, make sure the distance between the
magnet and the sensor is less than 1mm.
HTS-ORPM (RPM Sensor)
The Optical RPM sensor was made to be used with larger, outdoor, use helicopters.
Installation is simple, attach it to the boom and connect it to the sensor station.
It can read from 0 to 50,000 RPM.
- The readout can be inaccurate and inuenced by the weather condition
- For a more accurate reading, install the sensor as far away from the y bar paddles
as possible.
Hitec’s GPS sensor is specially designed for R/C application, unlike conventional
single dimension GPS sensor, such as car navigation, the ve dimension cube
Antenna has been implemented to cover dynamic movement of R/C aircraft.
As a result, it could receive stable GPS information, even during 3D ight.
- When the system boots up for the rst time, the position recognition time is
usually slower, depending on the area you are in. Once it connects, it memorizes its
last location for about 4 hours. When the system reboots at the same location within
that four hour time period, the position recognition time will be signicantly shortened.
- During extreme 3D ight, the signal can be lost, if this happens try to stabilize the
aircraft until the connection is restablished.
