QWB-REM1002remote control transmitter

REV: 11/11/03 RemoteRemote Users’ Manual INTRODUCTION The RemoteRemote receiver and keyfob is a simple 5-button radio-frequency (RF) wireless remote control for the Apple iPOD. CONTENTS 1This Users’ Guide 1 5-button keyfob 1 RemoteRemote receiver with cable 13-volt Li-on battery (CR2032) REQUIREMENTS • Apple iPOD, third generation (10-, 15-, and 30-GB models) with dock connector • Headphones, powered speakers, or stereo receiver Please follow these simple steps to get your RemoteRemote up and running. INSERTING THE BATTERY Step 1: Remove the keyfob from its plastic shipping bag. Step 2: Carefully separate the top and bottom halves of the keyfob. (For best results, use a thin piece of rigid plastic, or use a small flat-blade screwdriver, being careful not to damage the keyfob. With the two halves separated, Take note of the positioning of the green board, so that you may reinsert it properly later.) Step 2: Remove the battery from its plastic bag, noting the “+” symbol on one side of the battery. Step 3: Place the green PC board on a flat surface, with the metal bracket (battery holder) facing up. (Do not handle the green board any more than necessary and treat it carefully. Avoid handling it in areas of high static electricity.) Insert the battery into the metal battery bracket, with the “+” symbol also facing up (towards the metal battery bracket). If you are unsure, please see “www.engineeredaudio.com/faq.html” for further guidance. Step 4: Once the battery is inserted, replace the green board within the fob. Make sure the notches in the sides of the green board line up with the guides in the fob. Step 5: Snap the two keyfob halves back together. (It’s a tight fit, so take your time.) CONNECTING THE RECEIVER TO THE iPOD Step 1: If the headphones are attached to your iPOD, remove them. Step 2: Remove the RemoteRemote receiver (with cable, labeled “RemoteRemote”) from its plastic shipping bag. Step 3: Insert the connector plug of the receiver into the headphones jack of the iPOD, making sure it is firmly seated. Step 4: Plug headphones into the stereo jack at the end of the receiver. Note that the receiver draws its power from the iPOD, even when the iPOD is off. If the iPOD is not to be used for a while, or is not being charged, unplug the receiver to prevent the draining the iPOD battery. SYNCHRONIZING THE KEYFOB AND RECEIVER The receiver and keyfob must be synchronized prior to use. This ensures that your iPOD is controlled by only your fob, and not by the fobs of other users nearby. Once you have completed the set-up steps above, you can begin the synchronization (also called “learning”) process. Note that some of these steps need to be done in a time-critical fashion, so you may want to read through the instructions first before attempting the procedure. You may also have to repeat these procedures more than once, as the receiver periodically “sleeps” and may not hear the synchronization command. Note: A receiver can be synchronized with 5 separate fobs. If you synchronize 6 or more fobs, the receiver will only work with (or “remember”) the last five fobs synchronized. Should you lose a fob and replace it, simply follow the synchronization procedure with the new fob. Step 1: Press and hold (simultaneously) both the Fast Forward and Rewind buttons for 5 seconds, then release. Step 2: Within an additional 5 seconds, press and release the Play button. Your receiver has now “learned” your new RemoteRemote. If the receiver and iPOD fail to operate properly at this point, repeat the sync procedure. REV: 11/11/03 ERASING SYNCHRONIZATION WARNING: Erasing should only be done when absolutely necessary. Once the erase command has been sent, as outlined below, none of the fob(s) previously synchronized will control your iPOD. Be aware that, if you have multiple fobs synchronized with the receiver, the Erase command disables ALL keyfobs, not just the fob from which it is sent. Step 1: Press and hold (simultaneously) the Volume up, Volume Down, Fast Forward, and Rewind buttons for 5 seconds, then release. Step 2: Press and hold the Play button 5 seconds, then release. Again, as above, if the procedure does not work the first time, repeat it. If you disable a fob and wish to re-enable it, simply follow the “Synchronizing the Keyfob and Receiver” steps listed above. BASIC OPERATIONS • Play/Pause: press and release to toggle between play and pause. Hold down for 5 seconds to turn the iPOD off. • Next Track/Fast Forward: press and release to skip to the next track. Hold down for fast forward within a track. • Previous Track/Rewind: press and release to skip to the previous track. Hold down for rewind within a track. • Volume Up/Volume Down: press and hold until the desired volume is reached. • Locking the keypad: To prevent the keyfob from transmitting, for example, when it is in your pocket, you can lock the keypad. Once the keypad is locked, it will not control your iPOD until you unlock it. Step 1: Press and hold (simultaneously) the Volume up and Volume Down buttons for 5 seconds, then release. Step 2: Press and release the Play button. • Unlocking the keypad: To unlock the keypad, simultaneously press and hold the Volume Up and Volume Down keys for 5 seconds. TROUBLESHOOTING If there is no iPOD activity using the RemoteRemote you should try these troubleshooting tips: 1.) Is the iPOD battery charged and the iPOD otherwise operational? 2.) Is the keyfob battery installed correctly? 3.) Does the keyfob battery need to be replaced? 4.) Has the receiver “learned” the keyfob? If not, go through the “Synchronizing the Keyfob and Receiver” process. 5.) Has the keypad on the fob been locked? If so, unlock it as noted above. 6.) Is the receiver cable firmly and correctly seated to the iPOD? 7.) Is the audio cable from the receiver (to the headphones or other speakers) firmly and correctly seated? 8.) If these steps still don’t help, please contact us. FCC STATEMENT This device complies with Part 15 of th…

RemoteRemote Keyfob Circuit Description The RemoteRemote Keyfob is a simple On/Off Keyed keyfob-style transmitter with an internal, integrated patch antenna. The keyfob receives its power from a small 3v Lithium button cell battery (type CR2032). The keyfob is normally in sleep mode until the user presses one of 5 buttons, which wakes the microcontroller (MC68HC908QT1 - operating at 3.2Mhz), and sends out manchester encoded data to the transmitter section. The transmitter section consists of a SAW resonator stabilized printed circuit LC tuned- tank transistor oscillator operating at a nominal frequency of 433.92Mhz.

RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a pre-selector. 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 98.3ºF with a humidity of 40%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied 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 radiated 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 highest readings were converted to average readings based on the duration of "ON" time. 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. 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.
