Grip-Module Troubleshooting

Introduction

This section describes how the troubleshooting should be done if there is something
wrong with the Nokia 7650 Grip-module (LS4). All parts of the Grip-module - the back-
light, current gauge, vibra, keyboard and hall-sensor - have their own flowcharts that
describe how problems can be solved. Although the hall-sensor is located in the LG4, its
troubleshooting is described in this section.
The following flow charts have some links to each other so they are linked to each other,
and in this way, the root cause of a problem can be solved. Please note also that there is
a separate troubleshooting section with flowcharts for the transceiver board (LG4).
