9 CHANNEL 2.4GHz AIRCRAFT COMPUTER RADIO SYSTEM
Hitec 2.4GHz System
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.
I. Basic Function: Low Onboard Battery Warning - for All Optima Receivers
When the Optima series receiver is powered up, it will automatically detect the battery voltage level and recognizes between
4 cell or 5 cell NiMH and NiCd batteries. (4 cell < 5.8V < 5 cell)
In case of a 2 cell LiPo battery being used, you can customize the battery warning level by using HPP-22 PC program.
- When battery level is safe (4 cell > 4.5V, 5 cell > 5.6V): no changes for LED lights.
- When battery level is low (4 cell < 4.5V, 5 cell < 5.6V): Blue LED glows constantly and the red LED will
blink fast. You will hear three-continuous beeping alarms from the module as a low receiver battery warning.
Upon hearing the alarm, we advise you to land at once.
II. Optional 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

Testing the FAIL-SAFE Setting
a. 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 one second HOLD period.
How to turn FAIL-SAFE Off and reactivate the Hold Mode
a. Switch on the transmitter, then the receiver. Wait for the system to boot and you have control over the model.
b. Press and hold the receiver function button for 6 seconds and release it. After 2 seconds the red and
blue LEDs will blink rapidly.
c. Immediately press the button once.
d. FAIL-SAFE Mode is now deactivated and HOLD mode is activated.
e. Turn the transmitter off, then the receiver off.
f. Turn the system back on to use it.
Note
- If FAIL-SAFE is deactivated, the FAIL-SAFE position settings are also deleted!
- The FAIL-SAFE settings should be checked every time before you run the engine/motor.
Note
- The telemetry function is applicable for OPTIMA series receivers only.
Warning
- Low Battery Warning function is only for your guidance. 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.
