Rooms 87 Rooms Rooms How Do I Operate Devices? How Do I Operate Devices? General instructions for operating any device are given under “How Do I Operate Devices?” on pageE29. Some operations, however, are a little different depending on the room you are in. The following section discusses how devices may operate differently in different rooms. Operating Devices in Room A To select the speakers for Room A, press the button for Speakers–A on the front panel of the receiver. To set up PowerTouch to control Room A devices, follow the instructions under “How Do I Switch Control Modes?” on page 86. To control a second CD player from Room A, use , unless you are using a Kenwood 200-Disc CD Changer (see below). Kenwood CD-3280M, CD-2280M, DPF-J9010, DPF-J9020 or DPF-J9030 200-Disc CD Changers are specifically designed to work with the VR4900/ KRF-V9993D in a dual-room environment. Since they contain two CD players, one can play in Room A while the other is playing simultaneously in Room B. Use CD1 to control the changer for Room A and CD2 to control the changer for Room B. Operating Devices in Room B If you are using the receiver’s Speaker B outputs to power the speakers in Room B, press the button for Speakers-B on the front panel of the receiver to activate the speakers in Room B. The Listen Mode in Room A will automatically switch to stereo when you turn Speakers B on. To set up PowerTouch to control Room B devices, follow the instructions under “How Do I Switch Control Modes?” on page 86. 88 How Do I Operate Devices? Rooms 89 Chapter Four: Troubleshooting Troubleshooting Troubleshooting is how you determine what part of a complex system (like a home theater system) is at fault when the system isn’t working how you think it should. When you troubleshoot a system, you diagnose a problem by examining and eliminating possible causes until there’s only one left. Troubleshooting is easiest when you start with the most obvious, most common, and most likely and work from there. Diagnosing your own problems can save you time and aggravation—the better you understand how to troubleshoot and adjust your own system, the less time you have to: • spend on the phone with a customer service representative • do without your receiver because it’s “in the shop” There are some basic steps to good troubleshooting: 1. Verify the exact conditions when the problem occurs. This is the most important step in troubleshooting. Whether you fix it yourself or have to describe it to a technician, you are much more likely to really solve the problem if you know the exact circumstances surrounding the problem. For example, if you don’t hear anything through the speakers, it’s useful to know if it only happens when you are listening to CDs. Knowing that eliminates the speakers themselves as part of the problem. The more you know about when a problem occurs, the more likely it is that you or the technician can solve it. 2. Check each part of the signal’s path from source (such as a CD player) to speaker. You may also want to test the assumptions you made in step 1: maybe you haven’t listened to your MD recorder in a while— is there no sound from it as well? This step will really help narrow down the possible causes. Test all your connected devices and eliminate the ones where the problem doesn’t occur. When you’re done with this step, you’ll probably have found the problem. 90 3. Go over all device connections slowly and methodically. Double- check the settings on your remote. Wrong or loose connections are the most likely cause of the most common home entertainment problem: no sound. Use the Connection and Setup Guide to double-check your connections for each device. This is especially important with VCRs, tape decks, MD recorders, and equalizers, where it’s very easy to swap the “play” and “record” connections. You should also check your PowerTouch settings carefully. Did you set the input to the correct device? (you can also check the front panel of the receiver) Are you trying to listen to an analog source using a digital connection? 4. Cables (especially old ones) go bad more frequently than devices do. Always suspect the cable before its device. For one thing, it’s easier to test: simply swap the cable with one connected to a device you know is working. If the problem device works now, it was the cable. You can generally purchase new cables at most home electronics stores, or via the Internet. 5. User error is more likely than device failure. You probably don’t want to hear this, but it’s true. Use this manual to go over the steps to operate the receiver. Refer to the other devices’ manuals as well. 6. Instruction manuals are your friend. A good rule of thumb is to check the manual when something doesn’t work how you expected it to. If you read the manual before calling the store or taking the device back, you may find the solution to your problem much more quickly. The rest of this chapter presents some common problems, grouped by type, a...
