A Few Precautions

Please read this manual carefully. In addition to installation and operating instructions, it pro- vides information on various RB-1091 system configurations. Please contact your authorized Rotel dealer for answers to any questions you might have. In addition, all of us at Rotel wel- come your questions and comments.

Save the RB-1091 shipping carton and packing material for future use. Shipping or moving the RB-1091 in anything other than the original packing material may result in severe damage to your amplifier.

Be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will need in the event warranty service is ever required.

Placement

The RB-1091 generates heat as part of its normal operation. The heat sinks and ventila- tion openings in the amplifier are designed to dissipate this heat. The ventilation slots in the top cover must be unobstructed. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating. Likewise, remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its weight.
