PRODUCT DESCRIPTION Cellular Specialties, Inc. developed the Model 565AMPS 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. The external antenna is an omni-directional antenna. Internal antennas are usually omni-directional although various other types may be used for certain installations. The BDA amplifies both the "uplink" (phone to tower) and "downlink" (tower to phone) signals thus facilitating communications to and from the local cell site. There are four amplification stages on the downlink and four on the uplink for a total of +65dB nominal gain for each link. Both links have manual gain control settings accessed through DIP switches on the rear of the unit plus an AGC control for both the uplink and downlink. There are LED indicators for power on, transmitter on, uplink overload and downlink overload. An automatic amplifier safety shutdown circuit is also provided, which will disable the transmitters for ten seconds should the uplink or downlink overloads be reached to prevent excessive intermodulation and oscillation. The BDA is equipped with an interface connector designed for use with the optional CSI-MHH External Monitor. The pin-out of the MONITOR connector is shown below.

NOTES * The manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating must be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. ** Maximum total output power without exceeding the FCC allowable emissions of –13 dBm. *** Maximum safe input power at maximum gain with no damage. Cellular Specialties, Inc. reserves the right to change these specifications at any time without notice. MANUAL565 AMPS REV A 960-1008-002 6
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 re-generative feedback in the system. Feedback of this nature causes the amplifier to emit a continuous signal of maximum amplitude and could, in some cases, interfere with normal operation of the cell site. The minimum required isolation of 80 dB can usually be obtained by mounting the outside antenna away from the edges of the roof. The use of window mounts or other non-rooftop mountings should be avoided. MANUAL565 AMPS REV A 960-1008-002 7
SAFETY PRECAUTIONS !For INDOOR use, an Omni-Directional Antenna with a maximum gain of 3 dBi 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. The installation of an INDOOR antenna must be such that, under normal conditions, all personnel cannot come within 20 cm. (~ 8.0 in.) from any inside antenna. Exceeding this minimum separation will ensure that the employee or bystander does not receive RF-exposure beyond the Maximum Permissible Exposure according to section 1.1310 Limits for General Population/Uncontrolled Exposure. !For OUTDOOR use, an Omni-Directional Antenna with a maximum gain of 3dBi is authorized for use with this unit. Outside 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. The installation of an OUTDOOR antenna must be such that, under normal conditions, all personnel cannot come within 20 cm. (~ 8.0 in.) from any inside antenna. Exceeding this minimum separation will ensure that the employee or bystander does not receive RF-exposure beyond the Maximum Permissible Exposure according to section 1.1310 Limits for General Population/Uncontrolled Exposure.

AMPLIFER ADJUSTMENT 5.0 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. Both the uplink and downlink overload indicators should remain off. If either indicator is illuminated, the gain of the appropriate link should be reduced. If the gain of the amplifier needs adjustment the uplink and the downlink may be adjusted by means of the step attenuators on the rear of the unit. Attenuation from 0 dB to 30 dB in steps of 2 dB may be inserted by proper selection of the 2, 4, 8 and 16 dB attenuators. If satisfactory cell (or two-way) phone performance is not obtained when the phone is in close proximity to the interior antenna it may be necessary to decrease the gain of one or both of the links.

MANUAL565 AMPS REV A 960-1008-002 11 6.0 TROUBLESHOOTING All cables should be carefully checked for “shorts” and “opens.” If cables are O.K. it may be necessary to use a spectrum analyzer to examine the signal environment in which the BDA is operating. The existence of strong analog signals within the frequency bands can cause problems particularly on the downlink. In some cases additional filtering might be required to reject these unwanted signals. There may be some cases where the interference from outside signals is so great that they can not be filtered or otherwise reduced or eliminated without expensive and possibly prohibitive measures. In these cases it may not be practical to use the BDA for providing coverage at these sites.
