[. . . ] To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

To prevent fire or shock hazard, do not place objects filled with liquids, such as vases, on the apparatus. [. . . ] Lets you specify the location of your surround speakers for proper implementation of the surround effects in the Cinema Studio EX modes (page 44). This setup item is not available when the surround speakers are set to "NO" (page 34). Lets you set the distance from your listening position to the surround right speaker. Surround right speaker distance should be set from a distance equal to the front speaker distance (A) to a distance 4. 5 meters closer to your listening position (D). However, it is not possible to set the center speaker further than the front speakers. Also, the center speaker cannot be set more than 1. Likewise, the surround speakers can not be set further away from the listening position than the front speakers. This is because incorrect speaker placement is not conducive to the enjoyment of surround sound. Please note that, setting the speaker distance closer than the actual location of the speakers will cause a delay in the output of the sound from that speaker. In other words, the speaker will sound like it is further away. For example, setting the center speaker distance 1-2 meter closer than the actual speaker position will create a fairly realistic sensation of being "inside" the screen. If you cannot obtain a satisfactory surround effect because the surround speakers are too close, setting the surround speaker distance closer (shorter) than the actual distance will create a larger sound stage. Adjusting these parameter while listening to the sound often results in much better surround sound. For other sound fields, speaker position is not so critical. Those sound fields were designed under the premise that the surround speakers would be located behind the listening position, but presentation remains fairly consistent even with the surround speakers positioned at a rather wide angle. However, if the speakers are pointing toward the listener from the immediate left and right of the listening position, the surround effects become unclear unless set to "SIDE/LO" or "SIDE/HI". Nevertheless, each listening environment has many variables, such as wall reflections, and you may obtain better results using "BEHD/HI" if your speakers are located high above the listening position, even if they are located to the immediate left and right. Therefore, although it may result in a setting contrary to the above explanation, we recommend that you playback multi channel surround encoded software and select the setting that provides a good sense of spaciousness and that best succeeds in forming a cohesive space between the surround sound from the surround speakers and the sound of the front speakers. If you are not sure which sounds best, select "BEHD/LO" or "BEHD/HI" and then use the speaker distance parameter and speaker level adjustments to obtain proper balance. This setup item is only available when at least one speaker is set to "SMALL" and the corresponding speaker indicator flashes on the display. ) mode allows you to listen to higher fidelity sound and select the decoding mode for listening to a 2 channel stereo sound as multi channel sound. [. . . ] If so, the service may be temporarily out of order. There is no picture or an unclear picture appears on the TV screen or monitor. Move your audio components away from the TV.
