HARMAN KARDON WRKW1000
Owner's Manual

Adjust the level control on the back of the transmitter.
1. Turn the level control counterclockwise all the way. 2. Play music through your audio system while turning this control clockwise in small increments, until the red LED on the front of the transmitter �ickers brightly only during the loudest passages. Wait a few seconds between changes to allow the transmitter to recognize the new setting. Note: If the LED doesn�t glow during the loudest passages or it glows all the time, the sound may be distorted. The setting is correct when the LED �ashes brightly only during the loudest passages.

What to do if your system isn�t working.
Problem: The light on the powered speaker is always orange and, despite turning the TUNE knob, signal cannot be locked onto. Solution: � Make sure that the transmitter is connected to its AC adapter, and the adapter to a working AC power outlet. � To verify that the transmitter is receiving power, increase its level control while playing music through the system. The LED should �ash red at some point, indicating that the transmitter is powered. Reset the control to its original position after the test. � Slowly adjust the tuning dial until the tuning light glows green. � Adjust the Frequency Selector Control on the rear of the transmitter. � Reposition the speakers slightly. Remember that slight changes (even a few inches) in speaker placement can affect system performance. � The distance between your WRKW1000 transmitter and speaker(s) may be farther than the system�s maximum range for your speci�c usage and environment. See the opening paragraph of this owner�s manual regarding some of the many conditions that may reduce your system�s operating range. In such instances, you will need to use the WRKW1000 speaker(s) in a location that is closer to the transmitter and then repeat the steps above. Problem: Sound is distorted. Solution: � The transmitter may be getting too much volume. Make sure that the red LED on the transmitter only �ashes brightly on loud musical passages. � Slowly adjust the tuning dial until the tuning light glows green. � Reposition the speakers slightly. Remember that slight changes (even a few inches) in speaker placement can affect system performance. � Adjust the Frequency Selector Control on the back of the transmitter. � Re-adjust the TUNE knob on the powered speaker after having performed either of the two steps above. � If none of the above works, you may have to raise the physical location of the transmitter or the receiver, or both, to clear obstacles and then re-check the steps above. � The distance between your WRKW1000 transmitter and speaker(s) may be farther than the system�s maximum range for your speci�c usage and environment. See the opening paragraph of this owner�s manual regarding some of the many conditions that may reduce your system�s operating range. In such instances, you will need to use the WRKW1000 speaker(s) in a location that is closer to the transmitter and then repeat the steps above.

Problem: No audio or very low volume level. Solution: � Check that the slide switch on the back of the speaker is set to the correct position. � Make certain both channels from your audio source are connected to the inputs of the transmitter. � Check that the speakers are receiving power. The LED should glow when the power switch is pressed in. � Make certain the Level Control on the transmitter is set correctly. � The distance between your WRKW1000 transmitter and speaker(s) may be farther than the system�s maximum range for your speci�c usage and environment. See the opening paragraph of this owner�s manual regarding some of the many conditions that may reduce your system�s operating range. In such instances, you will need to use the WRKW1000 speaker(s) in a location that is closer to the transmitter and then repeat the steps above.

Connect the speakers to the system.
Position the speakers where they will be used. Play music through your audio system while doing the following: 1. Plug the two large AC adapters into the DC IN jacks on the back of the speakers. 2. Turn the Volume Control to a ten o�clock position and the Tone Control to a twelve o�clock position. 3. Plug the AC adapters into a wall outlet. 4. Set the slide switch located on the back of each speaker. If both speakers are to be used in the same room in stereo, designate one of them as the �Left� speaker and the other as the �Right� speaker, and set the switches on the back accordingly. If only a single speaker is to be used in a room, or if both speakers are intended for use in a monaural application, set the switch(es) in the Mono position. 5. Push in the power switch of each speaker. Slowly adjust the tuning knob on the front of each speaker until the tuning light glows green. You should then hear your program material playing through the speakers. Fine tune the reception by slowly turning the tuning knob slightly to the right and to the left for best reception. In case you cannot get clear reception, move the speaker slightly to the right or left until reception improves. 6. Adjust the Volume and Tone controls to the desired listening level and enjoy your WRKW1000s. Note: The speakers (receivers) may require slight re-tuning from time to time due to changes in surrounding temperature, humidity, etc. This is normal.
