1 General

This document describes the test procedures for the electrical repair package.

2 Go/No-Go Test

This test verifies that the radio parameters of a mobile fulfil the GSM / WCDMA
specifications. A mobile is considered good if all measurements pass. All results will
be presented on the screen and can be printed out if a printer is available.

There are two options available for performing the GNG test, SERP GNG or a Stand
alone GNG.

There are two methods of running a Stand alone GNG test. The first is a script
provided by Sony Ericsson for the Anritsu MT8510B which can be downloaded from
Anritsu’s Website as described in the Installation Instructions, Electrical. The second
is to write a script in accordance with the GO/NO GO Test Script Specification,
Electrical which is located on CSPN.

3 Calibration

The Calibration Program in SERP should only be run as directed by the Electrical
Troubleshooting Guide or the Electrical Parts List.

NOTE! A Test Program must be loaded in the handset before performing

the calibration routine. After calibration the handsets must be re­customized with signalling SW.

3.1 Flashing the Test Program (ITP) into the Mobile

Flash the “W760 Test Program” software into the mobile by doing the following:

1. Attach a fully charged battery to the mobile.

2. Open the Emma application and log in.

3. Ensure the mobile is powered off.

4. While holding the “5” key, connect the mobile to the USB Flash cable. (Once the
Identification Process is running in the Emma window, you may release the “5”
key.)

5. Select the “W760 ITP” protocol and follow the on screen instructions.

NOTE! Under most circumstances, the display on the mobile will be blank

when the Test Program is installed.

3.2 Calibration Instructions

NOTE! For complete and detailed user instructions, see the SERP Users

Manual located in the SERPINFO.htm that gets placed on the
Desktop after SERP is installed.

1. On a PC with SERP installed, start the SERP program by double clicking on the
“RepairManager.exe” icon on the desktop.

2. Click on the “Settings” button in the SERP Window to verify the test instrument,
GPIB address and the COM Port matches the SERP settings.

IMEI” box of the SERP Window and click on the “Load” button.

5. In the SERP window, check either the “GSM Calibration” or “WCDMA
Calibration” box that applies.

NOTE! Due to the sensitivity of the phone from outside interference

during WCDMA calibration, a Shield box and Service Tool Test
Interface setup are required for WCDMA Calibration. These can be
also used for GSM Calibration.

2.1.1).

7. Connect the Sony Ericsson Programming Interface Cable to the mobile’s system
connector.

8. Click on the “Start Test” button in the SERP window to start the Calibration
