USagE PREcaUTiOnS

In addition to the Safety and FCC Compliance sections on the previous page, please observe the following precautions when 

installing and using your new Sanwa Gemini X 2.4GHz FHSS-3 radio control system.

l

  The receiver antenna consists of a coaxial cable and a reception wire (the thin tip at the end of the coaxial cable). When you 

mount the receiver antenna, do not bend the reception wire. Reception performance decreases if the reception wire is bent.

l

  The antenna wire is delicate, therefore, handle with care. Do not pull on the antenna wire with force. 

Do not cut or extend the antenna wire. 

l

  The coaxial cable (the thicker portion or the antenna) can be bent into gentle curves, however, do not 

bend the coaxial cable acutely, or repeatedly bend it, or the antenna core can be damaged.

l

  The antenna wire should be installed into a vertical plastic tube per your particular model's assembly 

instructions. Keep the receiver antenna as far away from the motor, battery, and ESC as possible.

l

  There is a danger of runaway operation if connectors shake loose during use. Make sure that the receiver, 

servo(s), and switch connectors are securely fitted.

l

  The receiver is susceptible to vibration, shock, and moisture. Take appropriate measures to protect against 

vibration and moisture. Failure to take appropriate measures could result in runaway operation or damage to 

the receiver. 

We suggest wrapping the receiver in shock-absorbing foam when installing it into your model.

l

  When installing the receiver, avoid contact with any carbon or metal chassis components.

l

  Contact between metal parts mounted on a model can result in electrical noise, which can adversely effect 

receiver performance and possibly result in runaway operation or damage to your model.

l

  With electric-powered models, be sure to fit the motor with a noise suppression capacitor. Without a noise suppression 

capacitor, excessive electrical noise generation can cause runaway operation and/or result in damage to your model.

l

  Use rubber anti-vibration absorbers with servos. Direct transmission of engine vibration to servos can cause servo failure and 

possibly result in runaway operation with damage to your model.

REcEivER PREcaUTiOnS

2.4gHz FREqUEncY BanD PREcaUTiOnS

l

  The 2.4GHz frequency band may be used by other devices, or other devices in the immediate area may cause interference on 

the same frequency band. Always before use, conduct a bench test to ensure that the servos operate properly. Also, conduct 

checks with the transmitter as distant as possible from your model.

l

  The response speed of the receiver can be affected if used where multiple 2.4GHz radio controllers are being used, therefore, 

carefully check the area before use. Also, if response seems slow during use, stop your model immediately and discontinue use.

l

  If the 2.4GHz frequency band is saturated (too many radio controllers on at once), as a safety precaution, the radio control 

system may not bind. This ensures that your radio control system does not get hit by interference. Once the frequencies have 

been cleared, or the saturation level has dropped, your radio control system should be able to bind without any problems.

TRanSMiTTER PREcaUTiOnS

l

  Turn the transmitter ON first and then turn the receiver ON. After using your model, 

turn the receiver OFF first, then turn the transmitter OFF. It can be dangerous if you 

activate the components in reverse order as the servos may start up inadvertently.

l

  Before use, double-check that the transmitter and receiver batteries have sufficient 

power.

l

  Never touch the transmitter antenna during use. Doing so may cause loss of transmitter output, resulting in loss of signal.

l

The transmitter antenna should be rotated and angled so that the antenna is as close to perpendicular to the ground as 

possible during use. After use, to prevent any chance of damaging the antenna, the antenna should be rotated and moved into 

the horizontal stowed position.

l

  Do not expose the transmitter or any other components to excessive heat, moisture, fuel, exhaust 

residue, etc.

l

  Do not press the Bind Button during use. The signal is interrupted while the Bind Button is pressed. It may 

also require a short time to restore the signal after releasing the Bind Button, which can be dangerous.

l

  If the outer case becomes dirty, it can be cleaned with a soft dry cloth. If the outer case becomes soiled, it can be cleaned with 

a damp cloth and liquid detergent. Do not use any solvents to clean the outer case. Solvents will damage the finish.
