Operation is subject to the following two condi- tions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. In accordance with FCC requirements, changes or modifications not expressly approved by Thomson multimedia Inc. could void the users authority to operate this product. This device generates and uses radio frequency (RF) energy, and if not installed and used properly, this equipment may cause interference to radio and television reception. If this equipment does cause interference to radio or television reception (which you can determine by unplugging the unit), try to correct the interference by one or more of the following measures: Re-orient the receiving antenna (that is, the antenna for the radio or television that is receiving the interference). Move the unit away from the equipment that is receiving interference. Plug the unit into a different wall outlet so that the unit and the equipment receiving interference are on different branch circuits. If these measures do not eliminate the interference, please consult your dealer or an experienced radio/television technician for additional suggestions. Also, the Federal Communications Commission has prepared a helpful booklet, How To Identify and Resolve Radio TV Interference Problems.

To use the remote control, point it directly at your receiver. Set up and Maintenance of the Receiver Provide spaces for sufficient ventilation as indicated: Do not connect to the AC power cords until all connections are completed. Do not use your set immediately after transferring it from a cold place to a warm place: there is risk of condensation. Do not expose your set to water and excessively high temperatures. After having disconnected your set, clean the case with a soft cloth, or with a slightly damp leather chamois. Never use strong solvents. Protect your Components from Overheating Do not block ventilation holes in any component. Arrange the components so that air can circulate freely. Do not stack components directly on top of each other. Allow adequate ventilation when placing your components in a stand. Place an amplifier near the top shelf of the stand so heated air rising from it will not affect other com- ponents. If you have a satellite receiver, you should place it on the top shelf.

One optical or coaxial cable is needed for each SAT receiver, DVD player or CD player. When optical or coaxial cable is used, the analog audio cables are still needed if recording through a tape or VCR is desired. This receiver provides one optical and one coaxial digital input for the connection of your components. Please connect your components (e.g. DVD, SAT or CD) to the appropriate digital inputs and press FUNCTION and then rotate MULTIJOG to match your connection. Note: Optical and coax cables carry only the audio portion of the signal. A video connection must also be established for a SAT receiver and DVD player. S-video provides the best connection for the video portion of the signal. Composite video (yellow RCA connector) can also be used. It is important that the same type of cable (S-video or composite) that is connected from the Home Theater to the TV is used to connect the SAT receiver or DVD player to the Home Theater. FRONT TERMINAL Remark: If you have a video camera, video game machine, or an extra VCR, connect it to VCR 2 jack at the front of the receiver DIGITAL INPUT Connect components capable of outputing Dolby Digital (e.g. DVD or SAT) or standard PCM (CD) format digital signals. Read section on Input Signal Setting under Advanced Sound Control carefully to adjust the matching input settings. If your CD player is equipped with digital optical jacks, use of optical cable is preferred. What you need is just one more optical digital connecting cord(not supplied). Plug it in the digital input jack of the receiver and select OPTICAL on the receiver setting (see details on pg 20 chapter Input Signal Setting). You can enjoy better sound quality brought to you by the optical cable. When optical cable is used, analog cables are still needed for recording to tape output. Note: This receiver has one digital optical jack only. Be sure that such connection does not prevent optical cable connection of other components (e.g. DVD program pro- ducers use surround mostly for subtle atmosphereics and ambience, and only rarely for special effects. A good surround mix doesnt call attention to itself; if it did, it would soon become distracting. Connecting for Power Make sure you connect all your other electronic components and the speakers before plugging your receiver into the outlet. Plug the power cord in the wall outlet, matching the wide blade of the plug with the wide slot in the outlet. Be sure to insert the plug completely. Using Headphones To listen privately through your audio system, use the PHONES jack on the receiver. However, make sure you turn down the volume before you put on the head- phones. Increase the volume to the desired level after headphones are in place. Once headphones are connected, “HEADPHONE DOWNMIX 2 CHANNEL” will scroll on display. This feature automatically converts multi-channel speaker outputs to 2 channel stereo for your listening pleas- ure. Hearing Comfort & Well-Being Do not play your headset at a high volume. Hearing experts advise against continous extended play. If you experience a ringing in your ears, reduce volume or discontinue use.
