Optima and Minima Series Receivers cont.
Compatibility:
The OPTIMA & MINIMA receivers are compatible with transmitters using the Hitec AFHSS 2.4 GHz system,
such as, Spectra 2.4 module or dedicated built-in module AFHSS 2.4 Hitec transmitters.
FAIL-SAFE/Hold Mode Selectable:
Servos and other accessories can be set with a FAIL-SAFE point if power to the receiver is lost.
Jumper*:
The jumper is installed at the factory and is used when the receiver is powered by an electronic speed
control, a commercially available B.E.C. (battery eliminator circuit), dedicated 4.8 to 6V. NiMH battery pack,
or regulated Li-Po battery. The jumper is removed when the receiver is powered using the SPC feature.
*These functions/ features are only for OPTIMA series receivers.

Optima and Minima Series Receiver Link (ID-Setting 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 transmitter are “bound”, no other transmitter can interfere.
Turn on the transmitter and select “Yes” to the “Ready to Transmit” prompt by
pressing the jog dial.
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.
Press the jog dial to
activate the receiver
selection and scroll
to the “Opti&Mini”
receiver.
Back at the receiver
selection screen, scroll
to BINDING and press
the jog dial to enter
the binding screen.
Select the type of receiver
you are using, either
Optima or Minima, and
push the jog dial to
confirm your selection.
Press the jog dial to save your
setting. When prompted to
change the receiver type select
“Yes” and press the jog dial to
confirm your choice.
Select “Yes” for binding.
Press and hold the link button on the Receiver and turn on the power.
Release the link button.
Release the Link button, both RED and
BLUE LEDs will be blinking rapidly to
