1. General Information 1.1 Introduction This manual provides information pertaining to the installation and operation of OPISYS’s USHR-800 “Ultra Slim Home” bi-directional amplifiers. This unit is for CDMA, GSM, and TDMA modulations in the PMS frequencies as shown in Table 1-1.

1.3 Description This product is designed for offices, hotel rooms, small parking lots, garages or small buildings, helping to improve communications signal and coverage by extending the coverage of a base station. Outdoor antenna receives from a base station, then USHR 800 bi-directional amplifier amplifies the signal. After amplification, the signal is passed through to the indoor antennas. Conversely, signals from handsets are amplified and retransmitted to the base station. 2. Installation 2.
2.4 Before Installation You will need to determine the following before beginning the USHR-800 installation: a. b. c. d. e. Base station location Location where the outdoor antenna is to be installed Location where the indoor antenna is to be installed Location where the USHR-800 is to be installed Length and type of coaxial cable needed to connect from the outdoor antenna to the bi-directional amplifier unit f.
must be shielded from moisture, such as rain, and excessive temperatures. The operating temperatures should be between -20 °C and 50 °C. 2.6.1 Turn-On Procedure Verify all RF connectors are tightened and cables and antennas are secured. Connect AC/DC Adaptor on the bi-directional amplifier’s DC IN connector. The Power indicator LED should be green. Make sure that no other LED is illuminated. If any other LED is lit, consult the trouble shooting page of this manual, or “2.6.

3. Operation 3.1 Introduction This section provides information for operating the USHR-800 bi-directional amplifier. 3.2 Operating Instruction 3.2.1 Power-up Connect the bi-directional amplifier to AC/DC Adaptor. If no FAIL condition is present, only the “POWER” LED will remain lit. The bi-directional amplifier is then operating properly. 3.2.2 Fail Status 3.2.2.1 Overdrive Fail There is one overdrive fail on the unit, for the up link.
The overdrive fail on the USHR-800 bi-directional amplifier is design to detect whether the over driving is transient or permanent. If the output power level of reverse path(=Up Link) exceeds prescribed limit, then reverse path is disconnected and the FAIL LED (RED) is on. Bi-directional amplifier automatically checks output power level every 1 minute of a 5 minute cycle when reverse path has over power . If reverse path still exceeds level then shut down mode continues for another 10 minutes.

For OUTDOOR use, an Omni-Directional Antenna with a maximum gain of 34dBi is authorized for use with this unit. Outside antennas must be positioned to observe minimum separation of 20cm. (~ 8 in.) 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.
