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 310Plus In-Building Amplifier (IBA) for use in enclosed structures where sufficient signal from local cell sites to operate cell phones was unavailable within the building. It is, of course, necessary that sufficient signal be available on the roof of the structure.

4.0 INSTALLATION Pre-installation Survey Note: The Installer should refer to the Safety Precautions, in the following section, for proper antenna selection and installation A pre-installation survey should be performed prior to commitment to installation. Measurement of Received Signal Strength Indication (RSSI) should be recorded throughout the building in all areas where cell phone coverage is desired.
800 MHz of approximately 3.5 dB per 100 feet is used. The coax used should be a nominal RG-8 type with a flame retardant rating except when installed in space where moving air (heating and/or cooling) exists. In which case the coax must be “plenum” rated. For long runs that exceed 150 feet, the use of low loss ½” coax is desirable. Of primary concern is the isolation between the outside antenna and the inside antennas.
! For OUTDOOR use, a Directional Antenna up to a maximum gain of 11dBd is authorized for use with this unit. The Outside antenna must be positioned to observe minimum separation of 120 cm. (~ 4 ft.) from all users and bystanders. For the protection of personnel working in the vicinity of outside (uplink) 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 IBA will need very little adjustment. After connecting the coax and powering up the IBA, the signal levels within the previously surveyed areas should be checked for adequate RSSI and Signal Quality Equivalent (SQE) 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 IBA.
6.0 TROUBLESHOOTING All external 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 sight that your handset uses in the area where the outside antenna is to be 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 IBA is operating.
