SAFETY OPERATION INSTRUCTIONS BEFORE USE Review this manual and insure that all conditions are compatible with the amplifier's specifications. Safe operation may be impaired if this equipment is not used as intended. GENERAL DESCRIPTION This symbol is marked in the manual and denotes important safety operation instructions. -
Page 4: Overview
BDA-PS7W/PS8NEPS-37/37-90-C for USA market and BDA-PS7/PS8-37/37-90-C for Canadian market, provides up to 37 dBm composite power and has up to 85db gain. FCC NOTE This is a Class B device. - Page 5 Refer to Figure 1 for the BLOCK DIAGRAM DESCRIPTION following discussion. The downlink path of BDA receives RF signals from the base station, amplifies the signal and transmits the signal, without changing the frequency, into a Distributed Antenna System at the direction of the mobiles.

Page 13: Installation
INSTALLATION DO NOT APPLY A.C. POWER TO THE UNIT UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE BDA AND THE ANTENNAS. Set the BDA on the floor or mount on a wall (where applicable). Using appropriate screws and anchors, attach the BDA to the wall at the four mounting holes on the side flanges. (Special version not shown in this manual). -
Page 14: Operation
OPERATION Refer to Figures 4,5 for adjustment access location, connectors and labels Variable Step Attenuator BDA gain that indicated in the spec can be reduced by up to 30 dB in 2 dB steps using the variable step attenuator. Gain adjustment is made with rotary switches located inside the BDA enclosure. -
Page 15: Diagnostics Guide
DIAGNOSTICS GUIDE The BDA provides long term, care-free operation and requires no periodic maintenance. There are no user-serviceable components inside the BDA. This section covers possible problems that may be related to the installation or operating environment. Gain Reduction Possible causes: Defective RF cables and RF connections to antennas, damaged antenna or Leaky cable Occasional Drop-out of some Channels Possible causes: One channel with very strong power dominates the RF output of the... - Page 16 APPENDIX 1 26-Pin Connector Mobile Antenna Failure contacts are not standard in the O26 pin- out and must be requested at time of order to be included.
