1.0 SAFETY GUIDELINES The general safety information in this guideline applies to both operating and service personnel. Specific warnings and cautions will be found in other parts of this manual where they apply, but may not appear in this summary. Failure to comply with these precautions or specific warnings elsewhere in the manual violates safety standards of design, manufacture, and intended use of equipment. Cellular Specialties, Inc.
2.0 PRODUCT DESCRIPTION Cellular Specialties, Inc. developed the Model 510smr900 Bi-Directional Amplifier (BDA) for use in enclosed structures where sufficient signal from local cell sites to operate cell phones was unavailable within the building. It is necessary that sufficient signal be available on the roof of the structure. The BDA is connected to an external antenna, usually on the roof, and to one or more internal antennas placed strategically throughout the area where phone service is desired.

4.0 INSTALLATION CSI recommends that all BDA installations be coordinated through the local wireless provider. Note: The Installer should refer to the Safety Precautions, in the following section, for proper antenna selection and installation ! WARNING! AMPLIFIER DAMAGE WILL OCCUR IF A HANDSET IS CONNECTED DIRECTLY TO THE BDA OR THE COAX THAT LEADS TO THE BDA. Important note: A high degree of isolation must be afforded to prevent any regenerative feedback in the system.
SAFETY PRECAUTIONS ! For INDOOR use, an Omni-Directional Antenna with a maximum gain of 3dBi is authorized for use with this unit. Inside antennas must be positioned to observe minimum separation of 20 cm. (~ 8 in.) from all users and bystanders. For the protection of personnel working in the vicinity of inside (downlink) antennas, the following guidelines for minimum distances between the human body and the antenna must be observed.

5.0 AMPLIFER ADJUSTMENT In most cases the BDA will need very little adjustment. After connecting the coax and powering up the BDA, the signal levels within the previously surveyed areas should be checked for adequate RSSI levels. Measurements should be made at the perimeter of the building both inside and outside. It is important that the RSSI levels measured outside the building remain close to those measured prior to installation of the BDA.
6.0 TROUBLESHOOTING All cables should be carefully checked for “shorts” and “opens”. The rooftop antenna, if directional, should be checked for proper alignment along the calculated compass heading. Typically, the directional antenna should be aimed at the same site that your handset uses in the area where the outside antenna is placed. If cables and alignment are O.K. it may be necessary to use a spectrum analyzer to examine the signal environment in which the BDA is operating.
