1. General Information 1.1 Introduction This manual provides information pertaining to the installation and operation of OPISYS’s USHR-800NI “Ultra Slim Home Bi-Directional Amplifier”. This unit is used at 806 ~ 866 MHz 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 806 ~ 866 MHz communications signal and coverage by extending the coverage of a base station. Outdoor antenna receives signal between 806 MHz and 821 MHz , then USHR800NI 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.
2.4 Before Installation You will need to determine the following before beginning the USHR-800NI 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-800NI is to be installed Length and type of coaxial cable needed to connect from the outdoor antenna to the repeater unit f. Length and type of coaxial cable needed to connect from the repeater unit to the indoor antenna 2.
2.6.1 Turn-On Procedure Verify all RF connectors are tightened and cables and antennas are secured. Connect AC/DC Adaptor on the repeater’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 “2.6.2 Antenna Isolation and Alignment” section. 2.6.2 Antenna Isolation and Alignment USHR-800NI is equipped with an over drive protection circuit.
DC IN TO MOBILE 2.8 Installation Example USHR-800NI can be installed with multiple indoor antennas as shown in Figure 2-8. In this example, a 6-way power splitter was used to split the signal to and from the indoor antennas.
3. Operation 3.1 Introduction This section provides information for operating the USHR-800NI repeater. 3.2 Operating Instruction 3.2.1 Power-up Connect the repeater to AC/DC Adaptor. If no FAIL condition is present, only the “POWER” LED will remain lit. The repeater 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. Over driving occurs when the RF output power of the Bi-Directional amplifier exceeds a prescribed limit.
4. Trouble Shooting If the repeater does not operate properly after installation, first make sure that the installation procedures as described in section 2 of this manual were followed correctly. Inspect each connection, both RF and AC, and connectors for a secure fit, checking to see if all the connections are made to the proper ports of the unit and the antennas. If the malfunction is due to an alarm condition, refer to the appropriate part of the section 3.2 of this manual.
