Outdoor antenna receives signal between 806 MHz and 821 MHz , then USHR- 800NI 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 2.1 Introduction This section provides information for the installation and setup of the USHR-800NI amplifier. The information consists of procedures for unpacking, inspection and preparation for the installation, as well as the actual installation and the setup. 2.2 Unpacking and Inspection Examine the shipping carton for damage before unpacking the unit. If the shipping carton is damaged, try to have the carrier’s agent present when the equipment is unpacked. If visual inspection reveals physical damage(s) to the equipment, you should send it back for replacement. Verify that the equipment is complete, as listed under packing slip. Contact OPISYS with any missing component. 2.3 Preparation for Use 2.3.1 Power Requirements The power supply of the USHR-800NI accepts 5.1 VDC. Power consumption of the USHR-800NI is approximately 2.6 Watts. 2.3.2 Operating Environment The USHR-800NI is intended for indoor use only. Do not install it where it might be exposed to the outside elements as this could result in destruction of the unit and other hazards. For normal operations, the environmental conditions should be as follow: Temperature range: –20 °C to 50 °C, Maximum Humidity: 95 % 6 2.4 Before Installation You will need to determine the following before beginning the USHR-800NI installation: a. Base station location b. Location where the outdoor antenna is to be installed c. Location where the indoor antenna is to be installed d. Location where the USHR-800NI is to be installed e. 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 2.5 Antenna Installation 2.5.1 Outdoor Antenna Select a site for your outdoor antenna, making sure you have enough signal strength at that location. Using coax cable, connect the antenna to the repeater. If you are using a directional antenna such as a Yagi type, the antenna should be installed so that it is in line of sight of the base station. Then, align the directional antenna toward that direction, and secure the antenna using provided mounting hardware. Use of a lightning arrester is highly recommended. By installing a lightning arrester between the outside antenna and the repeater, you can protect the repeater unit from electrical surge from lightning. 2.5.2 Indoor Antenna Install the indoor antenna at a convenient location. It should be free of metallic obstruction in order to have an effective coverage. Depending on the circumstance of the installation, either one or a combination of following antennas can be used: Ceiling mount patch antenna, Wall mount patch antenna, Corner reflector 2.6 Bi-Directional Amplifier Installation USHR-800NI is an indoor amplifier. Accordingly, the environment of the intended installation site needs to be considered. The repeater must be shielded from moisture, such as rain, and excessive temperatures. The operating temperatures should be between -20 °C and 50 °C. 7 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. 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 ampl…

The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the antenna height and polarization as well as EUT azimuth were varied in order to identify the maximum level of emissions from the EUT. The test was performed by placing the EUT on 3-orthogonal axis. The frequency range up to tenth harmonic of the fundamental frequency was investigated. Remove the EUT and replace it with substitution antenna. A signal generator was connected to the substitution antenna by a non-radiating cable. The absolute levels of the spurious emissions were measured by the substitution. Spurious emissions in dB = 10 lg (TXpwr in Watts/0.001) – the absolute level Spurious attenuation limit in dB = 43 + 10 Log 10 (power out in Watts) 8.3 Test Equipment Com-Power AL-100 Antenna, Cal.
