QE8403XXRemote Control Helicopter/Airplane Transmitter

Model No. 403XX Operation Instruction Preparation 1. Battery used on Transmitter is 6 pcs of Alkaline ‘AA’ batteries. Open the battery cover on the Transmitter, insert 6 pcs ‘AA’ Alkaline batteries inside the battery compartment and cover the battery door. 2. Screw in the antenna on the Transmitter 3. The battery on the helicopter is rechargeable battery, which is charge by a charging connector coming out from the Transmitter. Charging the helicopter battery Connect the charge connector on the Transmitter to the charge connector at the bottom of the helicopter. 2. Slide the switch on the Transmitter to the upper position and the light on the transmitter will turn red while charging battery. The charging time requires about 20 minutes but the charger circuit inside the Transmitter can prevent it from overcharging. Flying the Helicopter 1. Please find an indoor place which has as few obstacle as possible 2. Please try to close all windows so that there is no wind or moving air 3. Switch on the micro switch at the bottom p1 the helicopter (slide the switch to the back) 4. Place the helicopter carefully on the ground 5. Extend the antenna on the Transmitter to full length 6. Slide the switch on the Transmitter to the upper position, the light will turn green. 7. The left stick control the helicopter move up and down, firstly reset the left stick to the lowest position. Then 2radually move the stick up, you will see both rotor start to accelerate and up to a certain speed, the helicopter will start to go up. Then you can continue to move the stick up or down carefully to keep the helicopter at certain height. Try to avoid moving the stick too quickly. 8. The right stick control the helicopter move forward/backward and also turn left/right. The control is as follow: - If the right stick is pushed up from middle to the top, the helicopter will start to go forward. - If the right stick is pushed down from middle to the bottom, the helicopter will start to go backward. - If the right stick is pushed to the right side, the helicopter will start to turn right. - If the right stick is pushed to the left side, the helicopter will start to turn left. 9. If you feel you can no longer keep the height of the helicopter, that means the battery on the helicopter is running out and you need to re-charge the battery again. 10. After landing, please switch off the helicopter (slide the micro switch at the bottom of helicopter to the front).

Applicant: Interactive Toy Concepts (HK) Ltd. FCC ID: QE8403XX Operational Circuit Description Item 1: Transmitter (R/C) The circuit consists of transmit circuit and charging circuit; The transmit circuit is powered by 9v (6F22) battery. Subordinate Signal circuit and IC1 (MCU are powered by Q4 (VCC at approx. 4.4v). It is a typical series regulated power supply. IC1(MCU) applies 3-channel specialized program. When transmit circuit is powered up, LED glows in green color. When VR1 is in the 0 position, transmit signal is close to 0. When VR1 is adjusted, IC1 (MCU) P1.0 (or P1.1) will transmit pulse codes proportionally. If VR2 is adjusted, tail motor speed will change in two different directions. If VR3 is adjusted, the speed difference between two main channels will change. When IC1 (MCU) detects that the voltage of 6F22 battery is under 7v, LED will glow in green color. Pulse codes pass D1 (a variable capacity 2105). The codes then are modulated to 27.195MHz in the signal oscillation circuit that consists mainly of Q3 and are transmitted out to the air. L1,T1 and C1,C2,C3 are for antenna matching and harmonic restrain. IC2 and its simple outskirt circuit are for charging management of battery on Rx. It is a SOC. Charging output is 4.715v-4.225v. Charging current is 390-526mA. Item 2: Receiver: Receiver consists of ANT1 (antenna), Q1 (RF amplification), IC1/3661 (modulator-demodulator), Q2 (signal processor and phase reversing unit), IC5 (MCU) and IC4, IC6 (motor driving circuit). ANT1 receives FM signal for 27.195MHz. The signal is amplified through Q1 and de-modulated by IC1 (3361). After passed Q2, the pulse codes are output to IC5 P0.0. IC5 will de-code for 3 channels duty-variable pulse signal to control IC4 (9926) to drive the main motors or control IC6 to drive the tail motor. IC4 and IC5 are powered by chargeable 3.7v 250mAh Lithium Polymer battery. Subordinate signal circuit and MCU are powered by LDO regulator-ML62252.
