SAFETY INFORMATION
Important Safety Instructions
Read these instructions. The A/V receiver's cabinet may be cleaned by gently wiping with a soft cotton or microfiber cloth. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] Do not plug a composite video cable into an analog audio jack, and vice versa. Both the chrominance (color) and luminance (intensity) components of the video signal are transmitted using a single cable. See Figure 7.

Audio Connections
There are two formats for audio connections: digital and analog. Digital audio signals offer improved quality, free of distortion and with greater detail and presence. The HK 3490 uses two types of digital audio connections: coaxial and optical. Either type of digital audio connection may be used for each source device, but never both simultaneously for the same source. However, it's alright to make both analog and digital audio connections to the same source.

Digital Audio
Coaxial digital audio jacks are usually color-coded in orange. Although they look similar to analog jacks, they should not be confused, and you should not connect coaxial digital audio outputs to analog inputs or vice versa. See Figure 4.

Antennas
The HK 3490 uses separate terminals for the included FM and AM antennas that provide proper reception for the tuner. See Figure 8.
Coaxial
Optical digital audio connectors are normally covered by a shutter to protect them from dust. Input connectors are color-coded using a black shutter, while outputs use a gray shutter. See Figure 5.

Optical
The AM loop antenna needs to be assembled. The AM antenna leads are polarized, and it is important to color-match the leads and terminals to maintain the proper polarity. See Figure 9.
Analog Audio
Analog connections require two cables, one for the left channel (white) and one for the right channel (red). These two cables are often attached to each other for most of their length. Most sources that have digital audio jacks also have analog audio jacks, although some older types of sources, such as tape decks, have only analog jacks. For sources that are capable of both digital and analog audio, you may wish to make both connections. If you wish to record materials from DVDs or other copy-protected sources, you may only be able to do so using analog connections. Remember to comply with all copyright laws if you choose to make a copy for your own personal use.

To enjoy XM satellite radio, purchase an XM antenna module designed for use with XM Ready devices and a subscription to the XM service. We recommend the XM Mini-Tuner and Home Dock Bundle, available at www. xmradio. com. The older Connect-and-Play module is also compatible with the HK 3490, but it may no longer be available in your area. An XM Ready-compatible module uses the special connector on the HK 3490's rear panel that allows you to use the receiver's tuner, including its 40 preset station locations and remote control. [. . . ] NOTE: If there are a large number of FM stations in your area, Auto Preset will overwrite any presets you programmed previously. Stations with exceptionally strong signals may be programmed into more than one preset.
Recording
Two-channel analog audio signals, as well as composite video signals, are normally available at the appropriate recording outputs. Thus, to make a recording, you need only make sure to connect your audio or video recorder to the appropriate output jacks, as described in the Installation section, insert blank media and make sure the recorder is turned on and recording while the source is playing. You may monitor your recording if your recorder has separate record and playback heads. [. . . ]
