1. Introduction
This document titled “Service Manual” describes the product features of G1 model and, how
to find the defects and to repair within service level 1 and 2 when the phone is not operating
properly as expected. When a customer brings mobile phone for servicing, take a look at the
phone in detail, and carefully listen to the customer’s explanation of symptoms. Most of time,
water and humidity could be the reason for phone’s failure. After cleaning the board, blow some
hot air onto the circuit. This cleaning and blowing of hot air solves 30% of the mobile phone
problems. Many of time, proper cleaning of connectors and sockets also solve the problem. As
the components used on the mobile phone circuit are very small, one should use a luminarymagnifier to be able to properly view them.
