Binding / ID Link - The manual confused me on page 19. Seems like you must power on the RX while holding in the recessed link button. Is that correct?
.<snip> So exactly when do you depress the button and power on the RX?

30 October 2012:
Hitec AFHSS ID-Setup (Bind) Spectra Module V3.01(0), Optima Transceiver 6, 7 & 9ch V2.02(0) & Minima Receivers - quick reference.

07 Oct 2011 - LED Update:
Blue LED on Optima V2.02 may not hold steady after ID setup, just a very brief flash.
Red LED then holds steady.
Cycle power both TX & Optima to complete and then range test as usual.

Current firmware for optimum performance:
. Aurora 9 V1.08(1) 10 July 2011
. Optic 6 Sport V1.04(1)
. Spectra 2.4Ghz Module firmware V3.01 18 April 2011
(How to update Hitec TX with fixed "modules" such as Optic 6 Sport & Optic 5)
. Optima 6, 7 & 9 Ch Transceiver Firmware V2.02(0) 07 Oct 2011
. HPP-22 Software Version V1.14(0) - 18 January 2013 (Details and pictorial "How to" install)

History - Instructions relating to earlier firmware now moved to bottom of page.

[see also Aurora Manual (page 20 ) under "Set-up and Use of the Hitec 2.4GHz System" - Range Check Function]
AFHSS - Power Down for Range Check is 1mw - tested to at least 1/4 mile.

a). Place the model on a wooden bench or equivalent, at least 60cm (two feet) above ground,
which is clear of any metal contamination, and tie down/secure safely. Small models can be held
in a safe position above waist level.

b). Receiver’s antenna should be in a Vertical position, 2nd antenna on 9ch transceiver at 90 degrees (Horizontal) position.
Antenna must not touch the bench or ground.
Transmitter to be held with TX antenna in a Vertical position.

c). Turn Transmitter On First then receiver and establish link.

d). Press the button on Spectra 2.4 Ghz Module for <3 seconds.
At first beep (red LED will go out if in Normal Mode and both LED will go out if in Scan mode), release button immediately.
Both Blue and Red LED's will start Flashing together with Continuous Beeping.
The <90-second countdown starts from the time button is released until beeping stops and the LED remain lit without flashing.
caution: if button is depressed for to long (6 sec), module will enter scan function and system will then need to be re-linked

e). Walk away 30m (100 feet) from the secured aircraft while simultaneously operating the controls on the transmitter.
Have an assistant stand to confirm that all controls are completely and operate correctly.
NB: It is imperative that all engine/motor equipped models are tested both with and without
the engine/motor running whilst throttle is moved up and down both slowly and rapidly through the full throttle
range to determine if there is any interference caused by the ignition system
(frequent cause of problems) or motor/ESC and if any vibration problems from bent shafts or bad propeller.

f). Exit the power-down mode.
Simply wait for the 90 seconds to expire and beeping stop or if wishing to stop power down
before the 90 seconds expires, press the button briefly again to escape.
(caution - holding button in to long will enter scan function set-up and RX will need to be re-linked)

g). Range Test without a helper holding/observing the model.
From system "Model" Menu, select "Monitor" then change Test INH to ACT and
Aurora will commence exercising servos automatically (at the rate set by the throttle).
Suggest model be secured on a stand/table so out of ground effect and surfaces more visible from 100'.

. Optima Transceiver (RX) - Servo Move Slower Than Usual - then Rebind.
...(Switched between Normal <> Scan mode with power off before process completed).

. Optima Transceiver (RX) - Servo Wag & Jerky Servo Movements Reasons & Cure - Do Not Fly With This Condition.
(...includes when switching on some ESC) .

. Optima Transceiver (RX) - Servos Stepping - Battery pack (power supply) failing under load.

h). If FAIL-SAFE is Deactivated, the FAIL-SAFE position settings are also deleted.

FAQ & Tips

1. Aurora 9 - After Market Accessories: Cautions re Opti-kill, Sparkswitch, Duralite, Powerbox
& ensure "R" type spark plug is in use.
2. If 2.4Ghz range test is short, try re-binding first.
(system may have been turned off in wrong order first time - refer procedures above)
3. Q. Receiver LED is correct but servos do not respond properly or appear sluggish to TX commands.
....A. This typically indicates that you have inadvertently switched into scan mode and then shut off the power
before the confirmation beep is heard to complete the mode change.
Solution = Continue to go through the rebinding process and eventually it will take.
....Q. I notice a beep from the module once in a while when flying, why?
....Q. I notice the blue LED flickers occasionally on Optima transceiver, why?
....A. A beep from the module and/or blue LED flickering on Rx indicates that your receiver battery voltage is
dropping too low under flight load.
This can result in a brown out if it drops too low.
Either battery is failing and should be replaced before you fly again or the Receiver battery/power supply
is simply not big enough to handle the current that all the servos draw under flight load. See also
. Aurora A9 Warning Alarms Battery voltage levels and consumption.
. Optima Transceiver (RX) - SPC - SPC connection & Lead Detailed plus Optima Current Draw/Amps.
. Hitec HPP-22 - Replacement Leads, Extensions & How To Update Optima buried in Models
4. Q: I disconnected the battery on my receiver, and the voltage alarm sounded on the transmitter
since I guess it was seeing 0 volts.
However, now I'm noticing that when I disconnect the battery, the voltage stays at its last
reading on the transmitter, and no alarm sounds?
....A: Because the telemetry cycles about 3 times/second, sometimes when you are unplugging the battery it
will sense the voltage drop and the warning will kick in, but sometimes it won't because once you unplug
the battery there is no signal going back to the TX.
This is a hit and miss thing due to the way the system works.
5. EP models without an On/Off switch:
Remove ESC lead and use the Loose Cell Battery Box & Switch harness
- Included with Aurora & Optima set to aid Linking and Set Up only for those with EP Models in lieu of using ESC/BEC.
[The Loose cell AA Battery Box Is Not intended For Use In Flight], or a switch harness and a 4.8<>6.0V battery pack.
Batteries must be fully charged, especially if loose NiMH in Battery Holder
6. Swap either standard or promo AFHSS 2.4Ghz modules between Teacher/Student TX to avoid
need for re-linking. (Aurora-Eclipse_Optic 6 and Futaba as listed)
7. Unexplained problems with Computerised Transmitters?
. Make sure battery is fully charged when programming.
. If Low Battery Warning sounds when flying - perform full range check, testing all mixes and trims before next flight.
This because a low battery frequently does not have the capacity to flash the trim and other adjustments to memory since TX was last turned on.
Programming and other trim adjustments are only saved at time or after transmitter is turned off.
NB: Like USB devices pulled out to quickly, If TX is turned off/on again to quickly, previous adjustments may not have been fully saved.

. If you are unable to accomplish a successful range check of 90 feet, DO NOT ATTEMPT TO FLY.
. Range check to be completed at the field, prior to first flight of the day, so as to be in the same RF environment.
. FAIL-SAFE settings should be checked every time before you run the engine/motor.

Update 18 Nov 2010:
Aurora Transmitter now includes the screwdriver (now with a rubber tip) that was supplied with
the 72 MHz Spectra module, Laser, Focus & Ranger TX to adjust trim pots.
. Use it to press the link button when binding a receiver to the transmitter.
. Use it as a stylus to navigate through the programming screens.

For those using earlier firmware or wishing to revert:

18 April 2011: New Procedures to cover differences between Transceiver and Receiver.
Optima V3.0+, Optima Transceivers 2.01+ and Minima Receivers
(earlier versions? see original procedures below)

Hitec 2.4 GHz AFHSS Equipment Updates - V3.0 refer major amendments under 2.i[/B] and attachments

20 Apr11 2011:

"New "smart scan" is basically an easier way of picking a new set of channels per your environment other than going into
scan mode and then back to normal mode which is what is recommended to use.
Scan mode was nice that it picked a new set of channels each time, but really unnecessary and some of the downfalls with having to cycle power on
both the TX and RX made it inconvenient. First of all note that the Hitec team has never done the scan mode to normal mode trick as we use the
same channels picked by normal mode and have flown at all the major events with zero issues.
The only time we suggest you use the scan function is if you need to avoid another device or if somehow you are having problems at a specific field.
Linking telemetry and non-telemetry Rx's... the technology requires a different binding method.
When binding the Optima (telemetry) RX's you would utilize the same exact procedure that you are familiar with, but with the new Minima RX's,
you must push the link button again to get the blue light flashing. - Mike"

. AFHSS - Receiver Manual V3.0 (jpg attached below)
. AFHSS - Spectra Module V3.0
. Hitec Minima - How to Set Up ID (Bind) - Video.


Original Instructions:

AFHSS Spectra Module & Optima V1 & 2, Aurora V1.03 to early V1.08

1. AFHSS - Normal & Scan Modes Explained includes Redundant (Dual) Receivers.

2. Each system and module / receiver set is paired at the factory for your convenience.
Use the following Linking (ID-Setting) sequence as you add Optima receivers into other aircraft
to be controlled by your Aurora or another TX with a Spectra 2.4Ghz module installed.

- System is in Normal Mode if the red LED is on both the module and receiver after connecting.
- System is in Scan Mode if the red and blue LED's are on both the module and receiver after binding.
Multiple (redundant) Receivers Cannot be used in Scan Mode.

Linking(ID-setting) when Transmitter is in Normal Mode:
25Feb11: attached a pictorial

a. Aurora - Turn on TX and while it is displaying the YES NO Transmit screen
> push and hold down the bind button > then press YES for transmit.
b. For other TX with Spectra 2.4 Ghz Module
- after installing the module on the transmitter, press and hold the button on the module,
turn on the transmitter, then release the button.
TX must be in PPM mode, will not bind if TX left in QPCM/PCM mode. Red LED will flash while it is searching for a receiver.
c. Press and hold the button on the receiver, turn on the receiver, red LED is on solid, release the button on the receiver.
Solid red and blue LED emits indicate it is linked with the module.
d. Solid red LED and blinking blue LED on the module indicate when the linking process is completed.
e. Turn Receiver Off First then Transmitter Off Last.
f. Turn Transmitter On First, red LED is solid on the module.
g. Turn Receiver On Last, red LED is solid, after a moment, when both module and receiver connected,
module will beep 4 times.
h. You should now have control over the model as the transmitter module and receiver are linked in Normal Mode.

Linking(ID-setting) when Transmitter is in Scan Mode:
25Feb11: attached a pictorial

a. For Aurora press and hold the button on the module, turn on the transmitter, then press
“Transmit Yes” on the front LCD screen, only then release the button.
For other TX, after installing the module on the transmitter, press and hold the button on the module,
turn on the transmitter, then release the button.
Red LED will flash while it is searching for a receiver.
b. Press and hold the button on the receiver, turn on the receiver, red LED is on solid, release the button on the receiver.
Solid red and blue LED emits indicate it is linked with the module.
c. Solid red LED and blinking blue LED on the module indicate when the linking process is completed.
d. Turn Receiver Off First then Transmitter Off Last.
e. Turn on Transmitter first, red LED is solid, blue LED is blinking on the module.
f. Turn Receiver On Last, red LED is solid, after a moment, the blue LED will also come on, and the module will beep twice .
g. You should now have control over the model as the transmitter module and receiver are linked in Scan Mode.


2. i.) Spectra 2.4GHz Module Firmware Version 3.01 - Update Released April, 18th, 2011
Changed “Scan Mode” to less complex “Scan Function”
Added compatibility with Hitec’s non-telemetry 2.4GHz receivers
Improved LED indicator error after Scan is done
Minima RX (non telemetry) can only be used with Spectra 2.4GHz modules which have been upgraded to V3.01.
New Manuals:
Spectra 2.4GHz Module Firmware Version 3.01 - manual V3.0 Manual - Addendum re Range Check.
Hitec 2.4GHZ Receiver V3.0- manual

ID Setting (Bind) must be done within 15ft. (5m) of the transmitter and receiver.
- Transmitter and receiver need to be at least 18in. (45 cm) from each other to bind correctly.
- In the ScanMode, if the transmitter or receiver has been shut off or disconnected for more
than one second
, both module and receiver need to re-boot (turn the power off, and back on)
- thus ScanMode cannot be rebound in flight.

LED Status Card . Digital .pdf copy which
can be printed and inserted as a page in manual or extra cards made.

3. Normal / Scan Mode - Switch:
Press and hold the Spectra 2.4Ghz Module button for six seconds.
Once two continuous beeps are heard, release the button immediately.
(Refer Module LED Status Indicator attached)
(Transceivers to be used will also then need to be relinked (rebound).)

4. SPC plug must be installed if not using a separate battery to power RX or on initial start up with
high power servos, RX voltage dips below reset (brownout) voltage.
Please refer to Optima RX - SPC Cable and use and attachment for full details.
. Optima RX - Multiple Batteries may be installed Dual batteries for redundancy or even one for each servo, may also assist.
. Optima working when powered via ESC/BEC but not when using a battery pack - FAQ
(ensure ability of pack under load, AAA batteries fail under even small loads)

5. POWER DOWN - Normal Mode & Scan Mode for Range Check as above:
