3.4Individual User Complaints

Individual user complaints are received from only one user or, theoretically speaking, from two or more users who are not related to each other, for example being in different areas etc.

Individual user complaints point to parts in the system that can only be accessed by that particular Portable Telephone. These parts are the Portable Telephone itself, the charger, etc. Unlike faults, for instance in Base Stations or system boards, which affect more than one user and mostly cause error reports, these types of faults cannot be detected by the system simply because of their nature. However, individual complaints are generally easy to trace.
