The company shall not bear any liability for any problems arising from the use of an uncertified antenna. 6.3.2 Isolation If the system wants to operate in the max gain state, the system requires sufficient isolation between the donor and service antennas. The system recommends isolation is higher than 15dB above the gain of the system. If isolation is not sufficiently ensured, the AOC function operates to reduce the gain to a level suitable for the ensured isolation. 6.3.3 Check points before turning on the Repeater 1) System Power Check DC electrical power to the repeater should be 12V, input electricity only after power verification. 2) Input RF Signal Range Optimal input RSSI into the repeater is -62dBm ~ -32dBm for all band. User should verify input condition of Donor ANT. If the input RSSI exceeds -32dBm, impose the using external attenuators should be used. 3) Isolation check between Donor/Service ANT The system must need that 95dB(Gain+15dB) isolation is secured to use 80dB of the maximum profit of the system. User should check its condition before installation. GSInstech Co., Ltd 6.3.4 Open for Service 1) Check points before open:
Verification of system installation status :
Electricity, In/Out antennas, cable connection, and equipment mount status. Verification of system accessories :
User should check all necessary accessories. Check receipt signal level :
Installer should check whether environmental conditions are in accordance with system specification to ensure that system operation will be optimized. GSInstech Co., Ltd 7. Troubleshooting 7.1 Troubleshooting In case of abnormal operation, technician should diagnose abnormality via remote access or directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs due to major alarm, repeater should first be powered off, and then technician should prepare the proper measurement equipment before trying to fix the problem. In most cases of major repairs, GST will simply replace the unit and conduct repairs at the appropriate facility. 7.1.1 Simple Troubleshooting Method 1) Check LED status at rear of module
- Normal operation: Green LED on. Alarming: Red LED on. 2) Technician should check external and internal connectors to ensure that all connections are tightly secure. These connectors should be cleaned regularly. 3) If technician thinks there is a serious problem, call after sales team for over-the-phone technical support. 1-913-469-6699. 7.1.2 Troubleshooting Guide Related to RF Item Check Point Troubleshooting System input power range (DL/UL)
