Save These Instructions

Compliance with FCC Regulations:

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

Protect Your Furniture

The system is equipped with non-skid rubber 'feet' to prevent movement. These feet are made from non-migrating rubber. However, certain furniture polishes, preservatives, or cleaning sprays may soften the rubber and leave marks or residue. To prevent damage, it is recommended to apply small self-adhesive felt pads to the bottom of the rubber feet before placing the product on fine wooden furniture.

Dear Jensen Customer

Selecting fine audio equipment is the start of your musical enjoyment. To maximize the fun and excitement, it's important to play it at a safe level. Sound can be deceiving; hearing comfort levels adapt to higher volumes. What sounds normal can be harmful. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, without distortion.
• Once a comfortable sound level is established, set the dial and leave it there.

Taking a minute to do this now can help prevent hearing damage or loss in the future. Jensen and the Electronic Industries Association's Consumer Electronics Group want you to enjoy listening for a lifetime.
