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.
