To do so, leave the charger and batteries hooked up overnight (16 hours). The first charge should be approximately 20–24 hours in order to fully charge both battery packs to peak capacity. The charger supplied with this system is designed to recharge your batteries at a rate of 50mAh for the transmitter and 120mAh for the receiver battery pack. Transmitter Only The center pin on all JR Remote Control Systems is negative. Therefore, the center pin on all JR chargers is negative, not positive. This is different from many other manufacturers' chargers and radio systems. Beware of improper connections based on "color-coded" wire leads, as they do not apply in this instance. You must make sure that the center pin of your JR transmitter is always connected to the negative voltage for correct polarity hookup. Important: Please note that the charging polarity of the transmitter and receiver are different. 9XP6102 - Introduction CENTER PIN IS NEGATIVE OUTSIDE IS POSITIVE RIGHT SIDE OF TRANSMITTER RED–POSITIVE / BROWN–NEGATIVE / ORANGE–SIGNAL RED TO NEGATIVE BLACK TO POSITIVE CHARGER PIGTAIL FOR TRANSMITTER CHARGER PIGTAIL FOR RECEIVER CHARGER 4.2 The pilot lamps should always be on…

Page 6 Technical Report Transmitter Model XP6102 FCC ID# BRWXP6102 3.2 Block Diagram (Reference is made to Figure 5.1) The (up to) four control potentiometers are at the left side of the schematic drawing. The control potentiometer, which is mechanically coupled to the control (joy) stick, is supplied with the regulated 5.0V voltage. The wiper on this pot is exactly centered in the neutral control stick position. All analog processing is performed as deviations from this center (reference) voltage. After the mixing of each channel, control voltage is changed to Pulse Train, through encoder circuit. The oscillator consists of an ECO type oscillator, excited by a quartz crystal. The crystal supports oscillation at the crystal's fundamental frequency (approximately 18MHz). The tuned circuit in the oscillator transistor's collector is tuned to the second harmonic of this frequency (approx. 36MHz). Q12 acts as a frequency multiplier (×2)/buffer; it drives the Power Amplifier (PA). Its output frequency is 4× crystal frequency. The straight-through PA stage is followed by a matching and band pass/low-pass network. This network matches the low PA stage output impedance to the whip antenna. The crystal load capacitance is affected by varicap D11, which is voltage-controlled by the "rounded-off square wave from the modulator transistor. The oscillator frequency is therefore switched in the rhythm of the modulate modulation pattern (FSK). Two DC Supply Voltage enter the RF section: 9.6 Volt "law" battery voltage supplies the PA stage only. All other stages, and bias current for all stages, including the PA, are derived from the regulated 6.0 Volt source on the RF board.

Page 4 Technical Report Transmitter Model XP6102 FCC ID# BRWXP6102 2.0 ENCODER THEORY OF OPERATION Reference is made to Figure 5.1, Transmitter Block Diagram. The functions of the encoder are to: * accept the analog voltages from the control inputs (joysticks, toggle switch). * process the analog voltages to create control mixing, adding, reversing, etc., as desired by the user. * sample these voltages in a cyclic rhythm under control of the system's internal timing generator. (This process is called commutation.) * process these analog voltages into binary weighted digital control words by means of an Analog-to-Digital Converter (ADC). * store these digital representations of the analog control input into a temporary memory (RAM). * supply this serial data stream to a buffer-driver for modulation of the RF Transmitter. * provide "housekeeping" of the encoding process by means of a quarts crystal controlled internal clock. * provide supply voltages to the RF section (Vcc = 9.6V battery voltage; Vreg = 6.0V regulated voltage). The entire program which controls the timing housekeeping, parallel-to-serial conversion process, and insertion of synchronization words and error detection codes is governed by a Central Processing Unit (CPU) under control by an internally stored program residing in Read-Only Memory (ROM). The CPU, RAM and ROM are all part of a single-chip microprocessor. Resolution of the Analog-to-Digital conversion process is ten (10) bits for a control accuracy of 1:2 10

Page 5 Technical Report Transmitter Model XP6102 FCC ID# BRWXP6102 3.0 THEORY OF OPERATION 3.1 General Reference is made to Figure 5.1, Transmitter Block Diagram. The HORIZON HOBBY DISTRIBUTORS, INC. Model XP6102 R/C Transmitter is sticks type Transmitter. It operates on any of the R/C frequency (Channels) allowed by the Commission in the 72 -73 MHz frequency band. Selection of the desired RF channel is made by Quarts crystal. This transmitter employs Frequency-Sift-Keying (FSK) of the carrier frequency, whereby the output frequency is either low or high due to the symmetrical FSK modulation process, the (center) output frequency cannot be directly measured, but must be calculated by taking the average of the high and low frequency states. m m m = shift from center frequency m = approx.1.8KHz F low fc f high f carrier = (f low +f high )/2 The peak-to-peak deviation of the FSK signal is approximately 3.6 KHz ("sliver modulation") Because of the unfamiliarity of the general public with the term FSK, this modulation technique is commonly named FM.
