FAIL-SAFE and Hold Mode Setup
If the FAIL SAFE function is set up and used properly but the receiver signal is somehow interrupted,
the servos will move to your previously stored FAIL-SAFE setup. If you do not activate the FAIL-SAFE
function, the signal is switched off after the HOLD period of 1 sec. This means that the servos become
“soft” and remain in their last commanded position under no load (this may equate to full-throttle!), until
a valid signal is picked up again. In the interests of safety, we recommend that FAIL-SAFE should always
be activated, and the FAIL-SAFE settings should be selected so as to bring the model to a non-critical
situation (e.g. motor idle / electric motor OFF, control surfaces neutral, airbrakes extended, aero-tow
release open, etc.).
Testing the FAIL-SAFE Setting
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.
Fail-Safe position
Switch on both.
Wait for the system to boot and you have
control over the model.
(approx. 6 second)
Release the button. After 2 seconds both red and blue LEDs blink alternately.
The receiver will count 5 seconds. During that time, move all the transmitter
sticks and other controls to the desired FAIL-SAFE positions (e.g. motor idle,
control surfaces neutral), and hold until the blinking stops.
When the blinking stops, the system will temporarily
the system to save and exit.

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.
