About your Wave® Music System IV

Your Wave® Music System IV provides an elegant way to bring high quality sound into any room.

System Features

  • Display provides access to system settings and information.
  • AUX connector enables playback from an audio device.
  • Headphone connector for private listening.
  • FM/AM tuner delivers precise radio reception.
  • CD drive provides access to even more music.
  • Remote control for point-and-click control from up to 20 feet away.

The demonstration CD
We encourage you to listen to the demonstration music CD included in the carton. Simply insert the demonstration disc and your Wave® Music System IV will play the CD automatically. For more details, see “Playing audio CDs” on .

The benefits of research
Over fourteen years of research by Bose Corporation brings you the benefits of award-winning proprietary acoustic waveguide speaker technology. Using this technology, a tube efficiently transfers energy from a small speaker to the outside air over a wide range of low frequencies. And, long waveguides, folded into intricate patterns, fit into products small enough to be placed
comfortably in your home. Your Wave® Music System IV features dual tapered waveguide speaker technology, connecting two speakers to two 26″ tapered waveguides which combine to deliver performance well beyond the size of the system.

Unpacking
Carefully unpack the carton and confirm that the following parts are included. May ship with multiple power cords. Use the power cord for your region.

Note: If part of the system is damaged, do not use it. Contact your authorized Bose® dealer or Bose customer service. Refer to the quick start guide in the carton for contact information.
Save the carton and packing materials for transporting or storing the system.

Setting Up the System

Placing the system

  • To enjoy maximum audio performance
    • Place the system across the room from where you listen.— Place the system within two feet of a wall, and avoid placing directly in a corner.
  • Place the system on a flat, stable surface.

CAUTIONS

  • Do not place the system on a metal surface. It could interfere with AM reception.
  • Do not place the system on a heat-sensitive surface. Like all electrical equipment, it generates some heat.
  • Do not use the system in a damp location or any other place where moisture can get inside.

Connecting to power

  1. Insert the small end of the power cord into the AC POWER connector.
  2. Plug the power cord into an AC (mains) power outlet.

Setting the clock
After plugging in the system, set the clock using the remote.

  1. Press and hold either Time – or Time + for about one second.
    Note: Press-and-hold operations require holding the button down for about one second. Initially, HOLD TO SET appears on the display and then quickly changes to – CLOCK SET – as the button is depressed.

  2. Release the selected Time button.

  3. Press Time – to adjust the displayed time backward or press Time + to adjust the displayed time forward until it matches the current time. You can also press and hold for rapid adjustment.

Listening to Other Sources

  • Primary stations and secondary services

  • Primary digital radio stations and secondary services are tuned in the same manner.

  • Primary digital radio stations generally broadcast the same number of hours as FM. If a primary digital radio station goes off the air while you are listening, or if signal strength drops to zero, UNAVAILABLE is displayed.

  • Secondary services are associated with a primary digital radio station. They may only broadcast periodically and may broadcast different program material than the primary digital radio station.

  • If a secondary service goes off-air while you are listening, or if
    the signal strength drops to zero, OFF AIR is displayed for two seconds. Then, the digital radio tunes to the associated primary digital radio station.

  • When tuned to a primary digital radio station or secondary service with a low signal, the display alternates between LOW SIGNAL and the station name.

Re-scanning digital radio stations
You can re-scan for available digital radio stations at any time DIGI-TAL RADIO is selected. This capability is useful if you change the location of the system or decide to connect the external antenna.

Once the track begins playing, artist name, song title, and elapsed track time will return to the display

Notes

  • The system will display artist name and song title information when available on music file CDs.
  • The audio quality of MP3 CDs is dependent on factors such as the encoded bit rate, the sampling rate, and the type of encoder used. The system supports MP3 CDs encoded at bit rates of 64kbps or higher, and sampling rates of 32kHz or higher. It is recommended that a bit rate of at least 128kbps and a sampling rate of 44.1kHz or better be used.
  • Playback quality of recorded CD-R and CD-RW discs is dependent on the CD recording process and software used
    to record the disc. An improperly recorded audio CD may cause the system to exhibit unexpected behavior.

  • Tap the touch pad on the top of the system (see page 8).

No sound|

  •  Increase the volume.
  • Eject and reload the CD.
  • Disconnect headphones from the system (connecting headphones mutes the speakers).

Poor sound quality|

  • If the bass is too heavy or low, adjust the bass level of the system using the setup menu (see page 15)
  • If listening to an external AUX source, use a stereo cable and make sure it is fully inserted.

Remote control is inconsistent or does not work|

  • Operate the remote control closer to the system.
  • Check that the remote control battery is installed with positive (+) polarity facing up.
  • Replace the remote control battery.
  • Check for interference from fluorescent room lighting, sunlight, or dust or dirt on lens.
  • Try the system in a different location.

AM reception is weak|

  • Turn the system slightly one way and then the other to change the direction of the internal AM antenna.
  • Move the unit farther from a TV, refrigerator, halogen lamps, dimmer switches, or other electronic equipment that generates electrical noise.
  •  If neither suggestion works, you may be in an area of weak AM signal coverage.

FM reception is weak|

  • Extend the power cord as much as possible. The power cord acts as an FM antenna
  • See “Using an external antenna”

CD does not play|

  • Select the CD source or press . The CD icon appears on the display.
  • Load the CD label-side up.
  • Check that the disc surface is clean, If not, try cleaning it.
  • Try another disc.
