Folding Antenna
1. Disassemble the Telescopic Antenna Mount and Folding Antenna
a. The first step is to “snap” the antenna apart. The lower part should be adjusted prior to the installation into
your transmitter, while the upper part connects to the module with the wire installed in step 4.
b. Note how to hold the antenna and where it separates. Grasp the two pieces and gently pull them apart.
Dispose of the used battery according to the instructions.

General Use Guidelines
Scanning Function
Link (ID-Setup or Bind)
Your Hitec AFHSS system uses a communication protocol that links and binds the Hitec 2.4GHz 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 Hitec
2.4GHz receivers to your transmitter, one per model memory as necessary.
Each module and receiver set is paired at the factory for your convenience.
Use one of the following binding methods to bind additional Hitec 2.4GHz receivers to your transmitter.
General Use Guidelines
To turn the system on and off, use the following sequence at all times:
Non-telemetry RXs (MINIMA & MICRO Series)
Telemetry RXs (OPTIMA Series)
The SmartScan is a unique function of Hitec’s AFHSS 2.4GHz technology to provide the user with the cleanest
& the most stable frequency channels in certain crowded 2.4GHz environments. From the firmware Ver.3.0 of
the Spectra 2.4 module, you can utilize “Scan” function more conveniently without complexity (previously,
Hitec’s 2.4GHz system was operated with two different modes : Normal and Scan mode which was a bit
complicated to use). The following explains how to use the Scanning function properly.
Press and hold the link button on 6Sec.
the Spectra 2.4 Module for about 6 sec.
Turn on the transmitter.
Press and hold the button on the module,
and turn on the transmitter.
Release the link button.
Release the link button when you hear two continuous beeps.
Range Check Mode
Range Check Function
It is critical that before each flight session you perform a range check that confirms the signal between the
receiver and transmitter is appropriate. Unlike the FM/PPM or PCM signal radios, 2.4GHz systems use a fixed
shorter, stubby transmitter antenna known as a rubber duck antenna. So, the traditional method of range
check, lowering the transmitter antenna, is not applicable.
CCheck if the BLUE LED is blinking.
If the RED LED is blinking, press
the link button for 2 sec., so
that the LED changes to BLUE.
CCheck if the RED LED is blinking.
If the BLUE LED is blinking,
press the link button for 2 sec.,
so that the LED changes to RED.
Press and hold the link button on the receiver and turn on the power.
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, effectively shortening the range to 30
meters or 100 feet. During this power-down mode, you should test the effective range by walking away from
the secured aircraft and carrying the transmitter to a minimum distance of approx. 30 meters or 100 feet.

The Spectra 2.4 Module will scan the frequency to find the

When the scan is completed,
the BLUE LED on the module stops blinking and glows steady.
Reboot the transmitter(turn off and on).
Follow the link process with your receiver.
How to use Power-Down
- Before each flying session, confirm the radio system is working properly.
- Before the engine or motor is started, turn on the system as explained above.
Warning Make sure all the servos and control surfaces are working properly.
If any control surface is not moving properly, do not fly the aircraft until the problem is solved.
- If you are unable to accomplish a successful range check of 30 meters or 100 feet,

Telemetry System
The Hitec Spectra 2.4GHz module and Optima series of 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 of receivers are 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
- When the battery level is safe (4-cell > 4.5V, 5-cell > 5.6V), no changes will appear to the LED lights.
- When the 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 beeps, we advise you to land at once.
II. Optional Functions: GPS, FUEL, TEMP, O-RPM, M-RPM, VOLT, Amp 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 information.
- Low Battery Warning function is only for your reference. The actual battery level could be
different. Battery Memory Effects such as Lazy Battery Effect or Battery Memory could affect
the Low Battery Warning function.
Warning - When the 2.4GHz system and HV servos are used together, we strongly recommend using
fully-charged, large capacity battery packs and you must constantly monitor the battery status.
