Introduction Base Transceiver Station Equipment IN:BTSE BS 11 DRAFT A30808-X3247-B309-1-7619 CAUTION Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. 2 A30808-X3247-B309-1-7619 IN:BTSE BS 11 Introduction Base Transceiver Station Equipment Copyright (C) Siemens AG 1997 Issued by the Public Communication Network Group Hofmannstraße 51 D-81359 München Technical modifications possible. Technical specifications and features are binding only insofar as they are specifically and expressly agreed upon in a written contract. Important Notice on Product Safety Elevated voltages are inevitably present at specific points in this electrical equipment. Some of the parts can also have elevated operating temperatures. Non-observance of these conditions and the safety instructions can result in personal injury or in prop- erty damage. Therefore only trained and qualified personnel may install and maintain the system. The system complies with the standard EN 60950.
