In such cases, restrictive measures or actions may be necessary to ensure the safe use of RF energy. High Voltage The equipment has been designed and constructed to prevent, as far as reasonably, practicable danger. Any work activity on or near equipment involving installation, operation or maintenance must be, as far as reasonably, free from danger. Where there is a risk of damage to electrical systems involving adverse weather, extreme temperatures, wet, corrosive or dirty conditions, flammable or explosive atmospheres, the system must be suitably installed to prevent danger. Protective Earthing Equipment provided for the purpose of protecting individuals from electrical risk must be suitable for the purpose and properly maintained and used. Handling Precautions This covers a range of activities including lifting, lowering, pushing, pulling, carrying, moving, holding or restraining an object, animal or person. It also covers activities that require the use of force or effort, such as pulling a lever, or operating power tools. Electrostatic Discharge (ESD) Observe standard precautions for handling ESD-sensitive devices. Assume that all solid-state electronic devices are ESD-sensitive. Ensure the use of a grounded wrist strap or equivalent while working with ESD-sensitive devices. Transport, store, and handle ESD-sensitive devices in static-safe environments.
USER MANUAL FOR RX-8139 ENU STATUS : 1-0-0 Copyright - refer to title page Page 13 3.2 SITE PLANNING CONSIDERATIONS Site Considerations The site considerations are listed below: • The distance between the donor antenna and the BS should satisfy line of sight requirements for maximum coverage area. The received spots accept field intensity at least -70dBm. • Make sure that TX and RX antennas isolation should more than the max gain that of -15dB. • Supply power near by the BS and easily access to the grounding spot. Installation Location Mounting surface shall be capable of supporting the weight of the equipment. In order to avoid electromagnetic interference, a proper Mounting location must be selected to minimize interference from electromagnetic sources such as large electrical equipment. Chassis output interface should install higher 1.2m than the ground. Environmental Humidity has an adverse effect on the reliability of the equipment. It is recommended to install the equipment in locations having stable temperature and unrestricted air-flow which should under the temperature that of -33oC ~+55oC and relative humidity of maximal 95%. The installation location for the product should be well ventilated. The equipment has been designed to operate at the temperature range and humidity level as stated in the product specifications in the datasheet. Direct sun light exposure to the equipment should be avoided. Provide additional shelter if necessary. Powering The power supply unit (PSU) provides power to all modules within the equipment. Depending on the product variant, it is recommended that the PSU operates on a dedicated circuit breaker or fused circuit. Grounding Requirement Verify that the equipment has been well grounded. This includes antennas and all cables connected to the system. Ensure lightning protection for the antennas is properly grounded. Cable Routing Depending on equipment configuration, a variety of types of cables are required. Where applicable, ensure cables are properly routed and secured so that they are not damaged. Cable requirements are as follow: Table 2: Cable Connection Cable Connection Description Coaxial Cable N to N Connect BS cable to DT port Coaxial Cable N to N Connect serve antenna cable to MT port Local Commissioning Cable RJ45 Connect with PC to realize local commissioning Manual Handling During transportation and installation, take necessary handling precautions to avoid potential physical injury to the installation personnel and the equipment.

Double check all connections including ground before applying power. Do not manipulate circuits or make changes when power is applied: • Visually inspect the power connection within the equipment. Ensure that the power cable is correctly and securely connected, including grounding wire, RF cable and optical cable. • Check grounding connection and verify that the ground resistance is less than 5Ω. • Connect the equipment to the PC installed with OMT software. • Check antenna system return loss which working frequency band return loss should less than -14dB (VSWR < 1.5) • The online commissioning can be commenced with following the commissioning steps. 4.2 MCU LED INDICATORS Three diagnostic LEDs are located on integrated module; each indicates the status of a particular function: LED_ALARMLED_MODEMLED_RUN Figure 7: LEDs Table 3: LED Indicators Identifier Colour Indication LED_RUN Green Operation indicator – Flashes once every second to indicate normal system operation. LED_ALARM Red Alarm indicator. ON = alarm; OFF = no alarm LED_MODEM Red N/A
USER MANUAL FOR RX-8139 ENU STATUS : 1-0-0 Copyright - refer to title page Page 20 4.3 COMMISSIONING PROCEDURES Perform the following procedures for system commissioning.
USER MANUAL FOR RX-8139 ENU STATUS : 1-0-0 Copyright - refer to title page Page 21 Table 4: Commissioning Commissioning Tasks Observation 1. On-line and Inquiry status z Activate the OMT Main window. The system Initialization will completed in about 2 minutes. z Click “Connect” button to enquire the repeater’s status. Proceed if there is no alarm; else check the failure and attend to the alarm. 2. Set Channel No. z Keep RF switch ON and set the channel number of the repeater’s operating frequency. 3. Adjust Downlink Output Power and align donor antenna z Observe DL input power from measured value. Align the direction of donor antenna until the DL input power reading is maximized. z Note: To ensure that the measured DL input power is accurate, one should set the DL ATT to “0” before performing the check. 4. Configure [Equipment ID] z Go to [Properties Info] and set [Equipment ID]. 5. Comm. Config z Enable the power supply by selecting “On” in [RF] -> [Switch]; go to [Properties Info.] -> [Comm. Config.] and set OMC Phones No. , the service No. of SMSC, Report Mode. 6. Select Monitoring Parameters z Select the equipment controlled and monitored parameters. z If the external devices are connected to the equipment for management, please enable in the [External Alarm Info.] Interface. 7. Test coverage area field intensity and adjust service antenna. z Use test-handset to verify field intensity within the coverage area. If needed, realign the service antenna to achieve the desired coverage. z Note: If during operation, the equipment gain could not be set to maximum or the output power is not high enough due to insufficient donor and service antennas isolation, then the antennas’ position should be changed to increase isolation. If the output power is too high and ALC is activated, then adjust the DL ATT to achieve optimal DL Gain. 8. Verify UL gain and ensure test call produces good voice quality and there is no interfering BTS z Adjust UL gain and perform test calls. Typically, the UL gain is set around 5dB less than DL gain. Perform test calls in the coverage area while adjusting UL gain if required. z Note: If the repeater is near the BTS and the test call performance is poor, this may be due to UL noise interference to the BTS. Users can calculate and determine if the repeater UL noise will interfere with the BTS. z Verify again that there is no unacceptable interference to BTS. End of Section
