5. Telemetry System
Hitec’s sensational 2.4GHz telemetry system brought you a whole new concept of being an
R/C flyer. Unlike conventional system, your plane will give you a feed back during the flight,
such as low in fuel warning, range-out warning, battery current residual and much more
information can be given in the future, which will help you to concentrate more on your
flight not on other things.
I. LOW BATTERY WARNING:
Spectra 2.4 will recognize a receiver battery type automatically among 4 cell and
5 cell NiMH and 2 cell LiPo Battery.
Red LED will blink fast. You will hear three continuous beeping sounds for low battery warning.
II. RANGE-OUT WARNING:
Depends on the area you fly, as well as your model’s flight condition the maximum range also
could be varied. Approximately 200 meter before your plane loses connection the range-out
warning will be activated and start warns you with the alarm sound.
Also both LEDs will blink rapidly.
How to turn F-S OFF?
1. Do the same as “How to Setup” step 1 and 2.
2. Instead of setup F-S Position, push the function button once more.
- F-S Mode is now deactivated and Hold mode is activated instead.
How to setup:
1. Press and hold the button for more than 5 seconds, until both LEDs will turn on with
one long “Beed~” sound which indicates it is in Scan/Normal Selection Mode. Then release
the button to see the LEDs which indicates your current mode, Scan or Normal mode.
2. Only the red LED turns on with short continuous “Beep! Beep!” sound is notifying you,
it’s in Scan Mode.
3. Both LEDs turns of with short continuous “Beep! Beep! Beep! Beep!” sound is
notifying you, it’s in Normal Mode.
4. Press the button to switch between the modes.
Note
In a case FAIL-SAFE is deactivated, the FAIL-SAFE Position settings are also deleted!
4. Scan Mode Setup
Hitec’s 2.4GHz Spectra Transmitter and Optima X series receivers has two different modes to
scan the frequency. One is Normal Mode, factory default, and another is Scan Mode.
Each modes differentiated as follow:
- Scan Mode in Use : Every time system powered up, it scans frequency (channels) in the
area to choose the cleanest band to use. This can optimizes the frequency traffics depends
on the flight condition with other 2.4GHz radios.
- Normal Mode in Use : A Transmitter and a receiver will keep using the same frequency
(channel) band at the first time of ID setting.
Be noticed that using Normal Mode can be effected by various factors,
such as an area where you at, or a flight condition
(crowded 2.4GHz equipped system running area).
Check
Testing the Fail-Safe Settings
Move the sticks to positions other than the FAIL-SAFE settings, and then switch off the
transmitter. The servos should now move to the FAIL-SAFE positions previously stored,
after the HOLD period (1 sec.) has elapsed.
The FAIL-SAFE settings must be checked every time before you run the
engine/motor and brought up to date.
Note
3. Range Check (Power down) Mode Setup
Unlike the conventional PPM or PCM radios 2.4GHz system uses rubber duck antenna which
you cannot adjust the length. Instead, use Power-Down Mode to reduce the signal strength in
certain rate to shorten the length. Once Power-Down Mode is activated it runs for about
90 second, and the range become shorten in length to approximately 30 meter.
How to use Power Down?
1. Press the button on the module for 1~4 sec, then both LED will turn on with short two
continuous “Beep!” sound, then release the button. The 90-second countdown starts from the
time button released. The proper power down range should be approximately in
30 meter range.
Check
When case the range check finished within 90 second or entered in this
mode by mistake, press the button again to escape.

The factory default setup is Normal Mode.

6. SPC (Supplementary Power Connection) System
SPC (Supplementary Power Connection) System is exclusive receiver power supplement
system directly powering the receiver from the main power source of an Electronic Powered
Aerial Vehicles. Therefore, it could use up to 35 Volts for the receiver; however, you still need to
supply power for your own servos with the four or five cell NiMH receiver battery.
SPC system is made for later use of telemetry system such as GPS.
