2.4GHZ FREQUENCY BAND PRECAUTIONS

• 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.
• The response speed of the receiver can be affected if used where multiple 2.4GHz transmitters are being used, therefore,
carefully check the area before use. If response seems slow during use, stop your model immediately and discontinue use.
• If the 2.4GHz frequency band is saturated (too many transmitters turned ON at once), as a safety precaution, the transmitter
and receiver may not pair. 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 transmitter and receiver should pair without any problems.

TRANSMITTER PRECAUTIONS

• The transmitter antenna is mounted internally and is located in the left front side portion of the transmitter, below
the carrying handle (see diagram on page 7). Do NOT cover this area in any way during use! Doing so can block
the RF signal, resulting in loss of control of your model.
• During use, hold the transmitter so that its orientated as close to vertical as possible at all times. This provides the best RF
signal between the transmitter and the receiver. Try not to ever 'follow' your model with the transmitter,
as this can result in a weakened RF signal.
the outer case. Solvents will damage the finish.

RECEIVER PRECAUTIONS

The RX-482 2.4GHz FH4T Super Response SSL receiver features an internal antenna. Do to the internal antenna position,
this receiver is not suitable for use in R/C boats. It should be used in R/C cars and trucks only. The MT-S radio system
can be used with R/C boats if you use a compatible receiver that features an external antenna, such as the RX-472 2.4GHz FH4T
Super Response SSL receiver.
• Although the reception capability of this receiver is equal to our other receivers that feature an external antenna, because
the internal antenna is positioned lower in your model, the reception distance will be shorter in actual use.
• For the best reception distance possible, the top of the receiver MUST be toward the top of your model and the receiver
should be mounted as high as possible in your model. The receiver can be mounted inside a receiver box, however, the
antenna position will be lower and the reception distance may be shorter.
• Analog servos are not compatible with SHR or SSR Channel Response Modes. If using analog servos, you must use the NOR
Channel Response Mode. Analog servos can be damaged if you use them with SHR or SSR Channel Response Modes.
• Any brand and type of digital servo can be used with the SHR Channel Response Mode, however, only Airtronics or Sanwa
Super Response SRG digital servos can be used with the SSR Channel Response Mode. If your ESC does not operate correctly
with the Throttle Channel Response Mode set to SHR or SSR, change the Throttle Channel Response Mode to NOR.
• The receiver is susceptible to vibration, shock and moisture. Take appropriate measures to protect against vibration and
moisture. It's okay to wrap the receiver in protective foam rubber if desired. Doing so will not affect the reception distance.
• There is a danger of runaway operation if connectors loosen during use. Make sure that all connectors are securely fitted.
• With electric-powered models, be sure to fit any brushed motors with a noise suppression capacitor. Without a suppression
capacitor, excessive electrical noise generation can cause runaway operation and result in damage to your model.

SERVO CONNECTORS

The RX-482 2.4GHz FH4T Super Response SSL receiver uses Airtronics 'Z' connectors, which are electronically compatible with
the servos of other radio control system manufacturers. The connectors are rugged, but should be handled with care.
When unplugging the servo connector, don't pull on the servo wire itself. This could result in damage to the servo wire
pins in the plastic plug. Always grasp the plastic connector itself.
• To prevent possible damage to your servos or a runaway model, turn the transmitter ON first,
then turn the receiver ON. After running your model, turn the receiver OFF first, then turn the
transmitter OFF.
• Before use, double-check that the transmitter and receiver batteries have sufficient
power.
• Do not expose the transmitter or any other components to excessive heat,
moisture, fuel, exhaust residue, etc.
• 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
- = Negative (Black)
+ = Positive (Red)
S = Signal (Blue)
If using another brand of servo, double-check the polarity
of the servo connector prior to plugging it into the receiver.
