inTRODUcTiOn

We appreciate your purchase of the new Sanwa Gemini X 2.4GHz FHSS-3 radio control system. This Operating Manual is 

intended to acquaint you with the many unique features of your state of the art radio control system. Please read this operating 

manual carefully so that you may obtain maximum success and enjoyment from the operation of your new radio control system.

The Gemini X 2.4GHz FHSS-3 radio control system has been designed for the utmost in comfort and precise control of all types 

of model cars and boats. We wish you the best of success and fun with your new purchase.

Additional 2.4GHz receivers can be purchased and paired with the Gemini X transmitter through the Binding operation. 

Please note that due to differences in the implementation of 2.4GHz technology among different manufacturers, only 

Sanwa  and Airtronics  brand  2.4GHz  FHSS-2  and  FHSS-3  surface  receivers  are  compatible  with  your  radio  control  system. 

Please see your local Sanwa or Airtronics dealer for more information.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC 

Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This 

equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the operating 

instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not 

occur in a particular installation.

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the 

equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

l

  Reorient or relocate the receiving antenna.

l

  Increase the separation between the equipment and the receiver.

l

  Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

l

  Consult the dealer or an experienced technician for help.

This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada. Operation is subject to the following 

two conditions:

1)  This device may not cause harmful interference, and....
2)  This device must accept any interference received, including interference that may cause undesired operation.

WARNING:

 Changes or modifications made to this equipment not expressly approved by Airtronics may void the FCC authorization 

to operate this equipment.

RF Exposure Statement
This transmitter has been tested and meets the FCC RF exposure guidelines when used with the Airtronics accessories supplied 

or designated for this product, and provided at least 20cm separation between the antenna the user's body is maintained. Use of 

other accessories may not ensure compliance with FCC RF exposure guidelines. 

l

  Be certain to read this Operating Manual in its entirety.

l

  'Safety First' for yourself, for others, and for your equipment.

l

  Observe all the rules of the field, track, or lake where you 

operate your radio control equipment.

l

  If at any time during the operation of your model, should 

you feel or observe erratic operation or abnormality, end 

your operation as quickly and safely as possible. DO NOT 

operate your model again until you are certain the problem 

has been corrected. TAKE NO CHANCES.

l

  Your model can cause serious damage or injury, so please 

use caution and courtesy at all times.

l

  Do not expose the radio control system to water or excessive 

moisture.

l

  Please waterproof the receiver and servos by placing them 

in a water-tight radio box when operating R/C model boats.

l

  If you have little to no experience operating R/C models, we 

strongly recommend you seek the assistance of experienced 

modelers or your local hobby shop for guidance.

l

  The Low Voltage Alarm will sound when the transmitter 

battery voltage drops to the minimum threshold. If this 

occurs,  stop  using  the  transmitter  as  soon  as  possible, 

then replace or recharge the transmitter battery.

SaFETY

This radio control system operates on the 2.4GHz frequency band. The 2.4GHz connection is determined by the transmitter 

and receiver pair. Unlike ordinary crystal-based systems, your model can be used without frequency control.

This is a high-output full-range radio control system that should well exceed the range needed for any surface model. For 

safety, the user should perform a range test at the area of operation to ensure that the radio control system has complete 

control of the model a the farthest reaches of the operational area. Rather than operating the model, we recommend that the user 

enlist the help of a fellow modeler to walk the model to the farthest reaches of the track (or for boats, to walk the shore line well in 

excess of the operational distance of the boat), then test for proper operation.
