2AUBX-ERC-1ERC-1 Remote Control

ERC-1 Remote Control EAZYRC 1. Unplug the batter y from your plane. 2.Carefully plug the charger into the USB port on your computer or USB adapter . 3.Connect b atter y into the charger . 4. The charging proc ess tak es about 3.5 hours.For safety reasons, never charge the batter y f or longer than 4 hours. 5. While charging, the red LED indicator will be constant on.When the charging is finished, the red LED will be off. 1.Install 4AA batteries(not included) in the tr ansmitter . Transmitter assembly Charging Instruction Setup Instruction EN Binding Instruction Binding is the pr oc ess of pr ogramming the rec eiver to rec ognize the GUID(Globally Unique Identifier) code of a single specific tr ansmitter . When a rec eiver is bound to a tr ansmitter , the rec eiver will only respond to that specific transmitter . Binding steps 1.Keep the transmitter switched OFF, throttle joys tick at buttom position. 2.Connect the batter y t o the plane, then turn on the transmitter within 5 seconds. 3. The rec eiver LED will flash for 3-8 seconds to bind automatic ally. 4.Aft er the rec eiver LED stop flashing, it means the binding proc ess is done. NOTICEKeep Gyro switch at Middle or Beginner position. NOTICEKeep the planes til in a calm environment for calculating the Gyro. Throttle Unlock(Arming) To pr event fr om damages, the throttle channel is locked each time when powering on your tr ansmitter . Follow below instruction to unlock the throttle. Turn the throttle stick up to max position until you hear a"beep"sound. Then turn the throttle stick down to min position until you hear a"beep"sound. Now the throttle is unlocked. CAUTIONKeep the propeller in distance f or your safety .

Ever y time when you power on the plane, it requires to activ ate the one-k ey U-turn function. 2. To use this function during flight, pr ess the one-k ey return to home switch button the plane will turnaround automatic ally, back to the opposite dir ec tion where it tak es o. No matter you flies the plane under manual control or gyr o assist mode, when you turn on the one-k ey return to home function, the plane will enter gyr o assist mode automatic ally to help stable flying back. 3. To quit this function, just pr ess ag ain the switch button, or control any servo stick(rudder/ele- vator), the plane will back to your control immediately. When you quit this function, the plane will back to the what the control mode it was. The one-k ey return to home function allows the plane to U- turn by the opposite dir ec tion th at the plane takes off. Follow below steps to activ ate the function. 1.Place your plane heading to the take-off direction. 2.Do NOT unlock the throttlepr ess the ac tiv ation button and hold for se ver al seconds until you he ar a"beep"sound, the rudder surfac e will respond, meaning the one-k ey return to home function is now activ ated. The one-k ey Rollover feature allows be ginner pilot to perform aerob atic ac tions by simply pr essing the button on transmitter . During flight, under gyro control mode, press the one- key Rollover button, the tr ansmitter will beep se ver al times. During the beeping, simply move the aileron stick to either dir ec tion for auto-r oll, or move the elevator stick to either direction for auto-flip. One-k ey Rollover One-k ey Rollover Instruction CAUTIONThis function is bound to the rec eiver , instead of to the tr ansmitter which means the plane will return ONLY to the opposite direction that the plane takes off. In other wor ds, this function can only make the air cr aft fly in the opposite dir ec tion of the se tting, and cannot be used as a fix ed-point return. It is no t based on the position at the time of setting. One-k ey U-turn Activ ation One-k ey U-turn Switch EN EN warning The device has been evaluated to meet general RF exposure requirements. The device can be used in portable exposure conditions without restriction.

version01 Dongguan Solid Model Technology Co., Ltd Declaration concerning Antenna Specification It is hereby declared that the product Model No.: ERC-1 FCC ID: 2AUBX-ERC-1 fulfills the requirement in FCC test relating to the antenna type. The device specified above confirms to the FCC recommendations for Cable Antenna antenna type(s) described below: Model No. of antenna: N/A Type of antenna: Cable Antenna(1/4 wave antenna) GFSK: Gain of the antenna: 0 dBi Frequency range: 2412 to 2480 MHz The mounting of the antenna is fixed to the radio module and no other antenna should be used. Company name: Dongguan Solid Model Technology Co., Ltd Address: 3/F, Building B, 3rd Industry Zone, Matigang, Dalingshan Town, Dongguan City, China 523810 City: Dongguan ZIP / Postal code: Country: China Place: Dongguan Date: 05/19/2021 Signature:

FCC ID: 2AUBX-ERC-1 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHZ)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f(GHZ) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. GFSK: Antenna Type : Cable Antenna Antenna Gain: 0 dBi Modulation Channel Freq. (GHz) Conduct ed power (dBm) Conducte d power (mW) Tune-up power (dBm) Max tune-up power (dBm) Max tune-up power (mW) Distance (mm) Result calculatio n 1g SAR Exclusion threshold SAR test exclusion 2.412 -18.8 0.013-18±1 -17 0.020<50.006203.00YES 2.442 -16.14 0.024-16±1 -15 0.032<50.009883.00YES 2.48 -18.85 0.013-18±1 -17 0.020<50.006283.00YES GFSK Conclusion: For the max result : 0.00988≤ 3.0 for 1-g SAR, No SAR is required.
