Programming functions are discussed in the same order that they appear in the radio. An explanation of the use and purpose of each feature is provided, followed by an illustration of its LCD display. A blank data sheet has been included at the end of each section. Once all data has been input for a particular model, it is highly recommended that you also record it on a copy of the data sheet provided. If you should experience memory loss or want to make changes to the current settings, this step will save you a great deal of time. XP7202 Transmitter The XP7202 synthesized transmitter allows on screen channel selection of channels 15 thru channel 60 via the computer. The system prevents accidental turn-ons by requiring acknowledgement of the selected channel before a signal is transmitted. The system incorporates a hi- resolution dot matrix LCD display offering sophisticated graphics that are easy to read and understand. Two model type programming offers airplane and helicopter pilots programming options that will meet the most demanding modelers needs. Control sticks are adjustable for spring tension and length. Twenty-model memory storage capacity allows programming of up to twenty separate helicopters or airplanes or you can program more than one set-up for a single aircraft. Two versions of the transmitter are available: Airplane and Helicopter. The switch positions are optimized for each model type however the programming is identical in both versions. 3.

Battery Charging 4A Transmitter/Receiver Note: It is imperative that you fully charge both the transmitter and the receiver battery packs prior to each fly session. To do so, using the included wall charger, leave the charger and batteries connected 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 150 mA for the transmitter and 120 mA for the receiver battery pack. Transmitter Polarity The center pin on all JR transmitters 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 may 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. 4B Charger The pilot lamps should always be ON during the charging operation. If they’re not, check to make sure that both the transmitter and receiver are switched OFF. Do not use this charger for equipment other than JR. The charging plug polarity may not be the same and equipment damage can result. During the charging operation, the charger’s temperature is slightly elevated. This is normal. 5. General Information 5.1 Control Stick Length Adjustment the XP7202 allows you to adjust the control sticks’ length. Loosen Tighten To adjust the stick length, use the 2 mm Allen wrench (supplied with your XP7202 transmitter) to unlock the setscrew. Turn the wrench counterclockwise to loosen the screw. Then, turn the stick clockwise to shorten or counterclockwise to lengthen. After the control stick length has been adjusted to suit your flying style, tighten the 2 mm set screw. If you desire longer sticks, JR offers a longer stick tip (JRPA047) that is approximately one inch longer than the standard stick. This stick is available at your local JR dealer. 5.2 Control Stick Tension Adjustment Note: Remove the transmitter Nicad battery, and six (6) transmitter back cover screws as shown on the previous page. Remove the transmitter back, being careful not to cause damage to any components Adjust each stick tension screw for the desired tension (counterclockwise to loosen stick feel, clockwise to tighten stick feel). When adjusting the throttle ratchet tension, make sure the adjusting screw does not touch the PC board after the adjustment is complete. 5.4 DSC Cord For proper DSC hook up and operation: 1. Leave the transmitter power switch in the OFF position. The transmitter will not transmit radio frequency (RF) in this position. 2. Plug the DSC cord (optional) into the DSC port in the rear of the transmitter. 3. The encoder section of the transmitter will now be operational and the LCD display will be lit. 4. Plug the other end of the DSC cord into the receiver charge receptacle. Turn the switch harness to the ON position. Note: The DSC function will only operate with the JRPA001 Deluxe Swit…

Page 4 Technical Report Transmitter Model XP7202 FCC ID# BRWXP7202 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 = 5.0V 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 6 Technical Report Transmitter Model XP7202 FCC ID# BRWXP7202 3.2 Block Diagram (Reference is made to Figure 5.1) The (up to) four control potentiometers are at the down 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 Q11(2SC4519)is an LC-type VCO(Voltage Controlled Oscillator), which is designed to oscillate with about 72.550MHz. Its output is led to amplifying stage for transmitting through a buffer(Q12),while it is also led to the PLL through a buffer(Q13). The pulses generated by the CPU are transferred to the VCO so as to modulate the radio wave. this part is strictly shielded from electric/magnetic noise. The IC3(BU2630F)is a PLL(phase Lock Loop). Exact 13.000MHz is generated by an internal crystal oscillator, and divided by 5,200 for 2.5kHz. VCO wave is also divided by a definite number, which is 29,004 in case of 72.510MHz,for getting 2.5kHz. Two 2.5kHz’s are compared in the phase and the VCO is so controlled that the error gets minimum, while the modulation is so fast that the filter between the PLL and the VCO cancels an error fluctuation. The set up of the frequency is done with Encoder unit. This frequency data is stored in the IC(H8/HD64F368FP) as an above-mentioned dividing number, and transferred to the PLL as the serial data while the transmitter is in normal operation mode. Frequency data can be changed only in system set-up mode with the power of the RF section being cut. Directly after it has turned on normally, though the CPU starts sending the PLL the data, the radio wave is still silent because the RF amplifier (Q1,Q2)is not supplied with the power yet. After a while, certain stabilizing time for the PLL, the Q4(2SA1298)starts to supply them with the power so that the radio wave is transmitted. Page 7 Technical Report Transmitter Model XP7202 FCC ID# BRWXP7202 The modulated signals supplied from Transmitter are PCM and PPM, and this modulated signal data is Set by IC(H8/ HD64F368FP). The modulated signal is conducted through phase-modulator, and the deviation value of the center frequency is fixed and changed by the wave form, symmetric in PCM and asymmetric in PPM. (For example, deviation in PCM is 0, the deviation in PPM is about 1.1KHz) This deviation value is supported by varying the impressed voltage to D6 (HVC350B). Q2 drives the Power Amplifier (PA). The straight-through PA stage(Q3) is followed by a matching and band pass/low-pass network. This network matches the low PA stage output impedance to the whip antenna. DC Supply Voltage enter the RF section: 12 Volt "law" battery voltage supplies the PA stage only. PLL stages, and bias current for all stages, including the PA, are derived from the regulated 5.0 Volt. 4.0 FAILURE ANALYSIS A failure analysis was conducted to ascertain that single-component failure will not result in unauthorized radiation. It should be noted that component failure would result in return of the unit to the factory, or to an authorized repair station. (Reference is made to Figure 5.2, Transmitter Schematic Diagram) Failure of any of the transistors (predominant failure mode: emitter-collector short) will result in the unit becoming inoperative: In the case of Q11 oscillator short, RF output will be non-existent. Q12,Q1,Q2 or Q3 failure will result in very low, if any, output. Failure of the MOD IN input (latch at 0 or 12 Volt) or modulator transistor Q9, Q10 and variable diode D4 (open or short) will result in carrier frequency. Although this failure would render the unit inoperative, the frequency tolerance would still fall within the channel bandwidth and tolerance requirements of .002% of 72 MHz = 1.44 KHz. When PLL circuit is broken, for example, crystal X1 break down, or IC101(BU2630) for PLL is broken, PLL will stop functioning. All other incidental failures will render the unit inoperative and because for return of the transmitter to the service facility.
