Introduction
IMPORTANT:
This document is intended for use by authorized NOKIA service centers only.
“Service Schematics” was created with focus on customer care.
The purpose of this document is to provide further technical repair information for
NOKIA mobile phones on Level 3/4 service activities.
It contains additional information such as e.g. “Component finder”,
“Frequency band table” or “Antenna switch table”.
The “Signal overview” page gives a good and fast overview about the most
important signals and voltages on board.
Saving process time and improving the repair quality is the aim of this document.
It is to be used additionally to the service manual and other training
or service information such as Service Bulletins.
