ConnectingtheHeadphone Systemi. Setup:Place the Transmitter in a location with enough clearance so that you canstore the Headphones on the Transmitter. This is important, because theTransmitter charges the Rechargeable Batteries (P) inside the headphones sothey are always ready for use. See Charging the Batteries on page 5.You can use the Surround Sound Headphones with up to three differentaudio/video components. The three inputs on the transmitter – two digitaland one analog – allow quick and easy connections for maximum versatility.ii. Connecting to Digital Components:a. Connecting Using the Supplied Toslink®Digital Optical Cable:1. Connect one end of theToslink®Digital OpticalCable (Q) to theDIGITAL OPTICALOUTPUT of youraudio/video equipment.2. Connect the other endof the Toslink®DigitalOptical Cable (Q) to theToslink®Digital OpticalConnector (F2) on thetransmitter marked“Digital 2”.b. Connecting Using a Digital Coaxial Cable: 1. Connect one end of theDigital Coaxial Cable(not included) to theDIGITAL COAXIALOUTPUT of youraudio/video equipment.2. Connect the other end ofthe Digital Coaxial Cableto the RCA-type DigitalCoaxial Connector (F1)on the transmittermarked “Digital 1”.COMPONENT VIDEORIGHT LEFT VIDEO OPTICAL D-COAXOUTPUTDVD PLAYERRED GREEN BLUEA B CA B CCHANNELCHANNELDIGITAL 1DIGITAL 1DIGITAL 2DIGITAL 2ANALOG 3ANALOG 3AC 7VAC 7VTRANSMITTERIICOMPONENT VIDEORIGHT LEFT VIDEO OPTICAL D-COAXOUTPUTDVD PLAYERRED GREEN BLUEA B CA B CCHANNELCHANNELDIGITAL 1DIGITAL 1DIGITAL 2DIGITAL 2ANALOG 3ANALOG 3AC 7VAC 7VTRANSMITTER- 3 -LocationofFunctionsTransmitter Front View:A.

Note: Make sure the electrical outlet is not a switched outlet - usuallydesigned to control a lamp - and remains ON at all times. This is important,as the transmitter base charges the headphones when not in use.ANTENNAIN TVOUTINPUTOUTPUTRIGHT LEF T V ID E ORIGHT LEF T VIDEOVCRA B CA B CCHANNELCHANNELDIGITAL 1DIGITAL 1DIGITAL 2DIGITAL 2ANALOG 3ANALOG 3AC 7VAC 7VTRANSMITTERA B CA B CCHANNELCHANNELDIGITAL 1DIGITAL 1DIGITAL 2DIGITAL 2ANALOG 3ANALOG 3AC 7VAC 7VTRANSMITTER- 4 -
TroubleshootingThe following troubleshooting guide takes you through some of the most common issuesand solutions associated with the installation and/or operation of the Wireless SurroundSound headphones.Issue Cause and SolutionNo Sound • Check that the AC Power Supply (O) is fully inserted into the wall outletand the barrel connector from the AC Power Supply (O) is firmlyconnected to AC Input Jack (E). When the AC Power Supply (O) isproperly connected and providing power, the Surround Sound ON/OFFLight (B) and Analog Input Indicator Light (C3) should be ON prior tomaking any selections.• Check that the headphones are turned "ON" and the red Power IndicatorLight (K) is brightly lit.• Check that the Rechargeable Batteries (P) are firmly seated in the BatteryCompartment (H) following the polarity markings in the BatteryCompartment (H).• Check that the audio source (DVD player, TV, VCR) is turned "ON" andproviding sound as it normally should.• Check that the headphone Volume Control (L) is turned up.• If the Surround Sound LED (B) is blinking, this indicates that the input isDTS encoded. This product does not decode DTS 5.1 encoded digitalsignals. Refer to your DVD, Satellite, or other manual to change the audiomode from DTS output to Dolby Digital or PCM output.Note: Usually you can select among PCM, Dolby Digital and DTS outputformats on DVD players and satellite receivers.• Check that the component’s digital sampling rate output is 48Ksamples/second or lower. This product does not support 96Ksamples/second. Refer to the component's manual to change the audiosampling rate output.Distortion/Static • Check that the headphone Tuning Indicator Light (N) is illuminated. Ifnot, push the ON/OFF/Tuning Control (M) to manually search for thechannel. If it does not lock quickly, change the Channel Select Switch (G)to one of the other two channels.• Check the batteries - they may be weakening.• Confirm the batteries are "good." When batteries begin to weaken, therecan be static breakup. If necessary, recharge the batteries.• Change the physical location of the transmitter. Locate it as high and freeof obstruction as possible. Avoid placing the transmitter directly on top ofa TV.• Check that the Digital Coaxial Output from the DVD, satellite, etc., isnot connected to the Analog Audio Inputs (F3).Sound from One • Check the left/right balance control on the audio source.Earpiece Only • Check that the Tuning Indicator Light (N) is illuminated.• Check the batteries – they may be weakening.• Check that both Analog Audio Input Connectors (F3) are properlyconnected, and that the audio source (VCR, TV, etc.) is equipped withStereo Analog Audio Output.VI- 7 -Listeningto theHeadphones1. Turn on the component you wish to listen to (DVD player, VCR, TV, oranother audio/video product).2. Press the Input Select Switch (D) to choose the device you wish to listen to,i.e., Digital 1, Digital 2, or Analog 3.3. Press the Surround Sound ON/OFF Switch (A) to turn the effect ON orOFF depending on the source material you wish to listen to. The virtualSurround Sound should be on for all Dolby Digital or Dolby Pro Logicencoded source material. All stereo music CDs, cassette tapes, or AM/FMradio should be experienced with the virtual Surround Sound OFF. See Processing Modes below.4. Turn the headphones ON by pressing the ON/OFF/Tuning Control (M).The headphones may take a few seconds to tune.5. Put the headphones on your head.6. Adjust the volume (L) to a comfortable listening level.7. When finished, power down the headphones by depressing theON/OFF/Tuning Control (M) until the Power Indicator Light (K) is OFF.Note: The headphones must be OFF for the batteries to charge properly.Make sure the Power Indicator Light (K) is OFF before charging.IVProcessingModes1. For multi-channel inputs (Dolby Digital inputs), the "virtual mode"processing uses 5.1 channel Dolby Digital decoding then virtualprocessing to create a 2 channel 3-D room equivalent output.2. For multi-channel inputs (Dolby Digital inputs), the "stereo mode"processing uses 5.1 channel Dolby Digital decoding/processing for anynumber of channels to create a 2 channel equivalent output. If the multi-channel input is stereo, then the 2 channel output is stereo (i.e., DolbyDigital Stereo).3. For Analog or PCM inputs, the "virtual mode" processing uses Dolby ProLogic decoding then virtual processing to create a 2 channel 3-D roomequivalent output.4. For Analog or PCM inputs, the "stereo mode" processing uses directstereo decoding to create a 2 channel stereo output.Note: This product does not decode DTS 5.1 encoded digital signals. V- 6 -
