PKXWT2000315 MHz Transmitter

For WHOFIW-Model 2000-1 Who’s First? You Are. Congratulations on your new purchase of Who’s First.™. Wireless? We’re sure this buzzer system will be the key to unlocking your group’s energy, generating excitement and adding “game show-like” spirit to your question and answer activities. Using this system, you will surely be ahead of the market. In addition to your students’ having fun, they will be really impressed with your sexy new technology. Wireless This new wireless option works just like our well established Who’s First™... It is a brand new version and works without the encumbrance of interconnecting wires. However because of the new technology, there are some precautions that should be observed. There are 5 touch boxes for the wireless version. The colors on 4 match the colors of the lights on the receiver. The 5th touch box is used by the person controlling the game and will reset the receiver at any time. It works the same as momentarily pressing the red reset button on the receiver. However, it cannot be pressed continuously to control the start of the game. It is also possibler to use the red reset button on the receiver instead of the wireless reset box. The dynamic range of operation is from 3 feet to 60 feet. The transmitter buttons when pressed will not work at less than 3 feet or more than 60 feet. Each switch/transmitter is furnished with a battery and that battery should last for tens of thousands of depressions. Fresh batteries are easy to obtain, either from The Trainers Warehouse or from popular battery vendors like Radio Shack. The identification number for the battery is CR2032. Each switch/transmitter furnished to you has been tested for hundreds of transmissions before being sent to you. There should be no problems with the operation of the unit during your games. In the event of any problems or questions, you should contact the factory at 800-299-3770 • • Trouble Shooting Before starting your game with the participating teams, it is a good idea to have each group press there button to be sure that the signal is being detected by the signal box. If no detection or spurious light signals are noted on the control box, confirm that the button is being pressed within the dynamic range of 3 to 60 feet. The range of Who’s First Wireless is adversely affected when the transmitters and possibly the receiver is situated on a metal table and shielded by Metal walls. Try the unit without being positioned on a metal wall. If spurious results are occurring, be sure that there is no strong radio signal in the area. With spurious results, the unit can be reset by pushing the red reset button on top of the receiver. Maintenance The only maintenance that might be required is replacement of the battery. This should not be required more than once per year with normal use. To replace the battery you must first obtain a battery. Radio Shack has the batteries in stock and if there should be a problem obtaining it from them, just call us and we can send you a replacement at the replacement cost. To position the new battery, just spread apart the walls of the black switch box on the two sides where the metal screws can be seen. The circuit board with the battery on the top side is immediately apparent. Press the round button near the center of the battery on the battery holder, and the battery will pop out. A small arrow on the side of the battery holder closest to the center of the board points to the button. The new battery is inserted with the + side up by pressing on the outside edge of the battery indicated by a small arrow on the outside edge of the battery holder. If time permits, you are welcome to send it back to us and we will replace the battery for you. Any other problems, you are always welcome to call us. 1-(800)-299-3770. We appreciate your comments. We would appreciate knowing how this product is working for you. As you can tell, we’re excited about Who’s First™; and, although we’ve already invested lots in its development, we do want to make it truly perfect. So, please do call or write with comments, suggestions, or questions . Good Luck and have fun! • Wired Operation This unit may be used with wires if it is desired. The circuitry is in place for wired operation but one precaution must be observed-To use this unit with wires, the batteries must be removed from each of the hand operated transmitter devices. Please call the factory if you desire to do this and the proper wires will be sent to you. Set-up Red, Yellow, Green, Blue It’s really important that the touch boxes are connected to the main module in the correct order. Notice the touch box labels specify “Connect this side to x color.” Please make certain you connect the indicated side of the box to the next unit. If you connect the wrong side of the touch box to the following box, you will cause the wrong lamp to light.. Using the 16 foot telephone- like cords connect the main module first to the red side of the red touch pad, then connect the yellow side of the red box to the yellow touch box. Accordingly, connect the green, then the blue. On the Main Module box, be sure to plug touch pads into the single upper phone jack, labeled “Touch Pads.” DO NOT plug Touch Boxes into the jack labeled “Extension Modules.” The main module can either lay flat or stand up on end. Rest each of the four Touch Boxes on a flat surface. As the touch sensors are located in the feet of the boxes, they will not work properly as hand-held devices. Power Source Now, plug the unit into any power source. There is no on/off switch. Once plugged in, the unit is ready to go. Multiple Modules Each Who’s First™ can be used as either a stand-alone units or as an integrated set. Any one of the units can be plugged into the power source for all to be operable. Once connected, the reset buttons are interchangeable. If you wish to expand Who’s First™ to accommodate additional teams, simply connect two or more of the Main Modules together. To do …

Trainer's Warehouse Transmitter Description The TH7107 transmitter IC, IC1, contains an internal oscillator phase locked loop which locks the oscillator to 32 times the external crystal frequency. Therefore a crystal frequency of 9.844Mhz produces an output frequency of 315.0MHz. The PLL loop filter components are C6, R1, C5. The frequency is FSK modulated by switching C2 in parallel with C1 with an internal transistor which is driven by the input to pin3. The frequency shift results in approximately a 50KHz output frequency shift. The output of IC1 is a balanced open collector so L1 and L2 provide the collector voltage, and C7, C8 form a tuned loop. CT1 is not used because C7 is selected for correct loop tuning. The output power can be adjusted by changing R3 sets current in the output stage. Q1,Q2,C10,R5,R9,R6,R11,C14 form a triggered monostable multivibrator which turns the transmitter on for approximately 180mS when one or more of the switches, SW1 through SW4, are pressed. In oder to reduce the effect of spurious signals, a tone of approximately 4.8KHz is transmitted. This is obtained by dividing the crystal frequency by 2048. IC1 contains an internal divider which produces ¼ the crystal frequency at pin 8. U1 is a CMOS divider which is used to divide the signal on pin 8 of IC1 by 512. The 4.8KHz signal on pin 13 of U1 is applied to the FSK input, pin 3 of IC1. TRAINERS WAREHOUSE FCC ID : PKXWT2000 JOB # : 155ZU1 EXHIBIT # : 10

RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz. The ambient temperature of the UUT was 72ºF with a humidity of 21%. REPORT #: T\TRAINERS\155ZU1\155ZU1RPT.doc PAGE #: 1 TEST PROCEDURES CONTD. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table. The table used for radiat- ed measurements is capable of continuous rotation. The spectrum was scanned from 30 MHz to 10th harmonic of the fundamental. Peak readings were taken in three (3) orthogonal planes and the high- est readings were converted to average readings based on the duration of "ON" time. Measurements were made by TIMCO ENGINEERING INC. at the registered open field test site located at 849 N.W. State Road 45, Newberry, Fl 32669. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. ANTENNA & GROUND: This unit uses the PCB inductor as the antenna. There is no provision for an external antenna.
