Telemetry System
The Hitec Spectra 2.4 System and Optima Series receivers feature full telemetry capabilities (except
Optima 6) and include a Low Receiver Battery Warning as a basic function.
Functions (Available with Optima 7 and 9):
Hitec offers a wide variety of telemetry sensors designed to work with both fuel and electric powered
aircraft. Check our website at www.hitecrcd.com for the latest available telemetry accessories.
Note
Warning
- The telemetry function is applicable for OPTIMA series receivers only.
- The actual battery voltage level could be different.
- When the 2.4GHz system and High Voltage servos are used together, we strongly
recommend using fully charged large capacity battery packs.
Range Check Function
It is critical that before each flight session, you perform a range check that confirms that the signal
between the receiver and transmitter is strong. To do a range check, use a power-down mode to reduce
the transmitter signal strength. During this power-down mode, you should walk away from the secured
aircraft while carrying the transmitter to a distance of approx. 30 meters, to test the effective range. The
model should exhibit no signs of signal loss during the range check.
2. Press the jog dial and back button simultaneously to enter the
System Menu list. From here, scroll to the SPECTRA function and
press the jog dial to enter the Spectra setup menu.
3. Scroll to the RANGE CHECK and push the jog dial to enter the
range check function.
4. If you are sure you want to proceed with the range check,
select “Yes” and press the jog dial to continue.
5. Walk away from the secured aircraft carrying the transmitter
to a distance of approx. 30 meters, to test the effective range.
Once you have completed the range check, push the jog dial to
end the range check.
1. Turn on the transmitter and select “Yes” from the “Ready to
Transmit” prompt by pressing the jog dial.
