2. Installing the Steel Antenna into the transmitter

a. Insert the steel antenna into the antenna hole of the Aurora 9, and turn it to            

    the clock wise direction to tighten up.

b. Turn the antenna clockwise until it is securely screwed into the transmitter.

Before each flight, it is critical that you perform a range check to confirm the 

signal between the receiver and transmitter is appropriate. Unlike 2.4GHz 

system the FM/PPM or PCM radios, use an extendable steel antenna. 

Therefore, the method of range check has to be different. Lower the 

transmitter antenna all the way to reduce the transmitter signal range to 

minimum level.

Once the antenna collapsed it will shortening the range to approximately 30 

meters or 100 feet. During the range check process, you should walk away 

from the secured aircraft carrying the transmitter to a minimum distance of 

approximately 30 meters or 100 feet without control loss.

- Do the range check before each flying session to confirm the 

  radio system is working properly.

- Do the range check before the engine or motor is started.

- Turn on the system as explained above and make sure all servos and

   control surfaces are working properly during the range check process

   within the range.

- If any control surface is not moving properly, DO NOT fly the 

  aircraft until the problem is solved.

- If you are unable to accomplish a successful range check of 

  30 meters or 100 feet, DO NOT ATTEMPT TO FLY.

Spectra Pro uses synthesize technology does not require classic crystal chips 

to change its frequencies. Plug into the Aurora 9 transmitter and select your 

preferred Frequency Channel matches with your receivers. In the case of 

multiple models are being used from one transmitter, you can connect as 

many Hitec receivers to your transmitter as necessary, one model per one 

model memory will be used.

- Connecting must be established within 15 feet of the transmitter and receiver.

- Make sure there is no one next to you are in connecting process.

- In case of synthesized receiver is being used for the connecting process,         

  setup the frequency channel from the Aurora 9 first then turn on the receiver.
