1 Introduction

Tester CTS is a value-for-money instrument for function tests, as well as detailed service testing on
digital mobiles. These tests are performed using a personal computer.

Application Software CTSgo is supplied with the tester.

The CTSgo program comes in two versions.

•

CTSgo for Windows 3.1 / Windows 3.11 for Workgroups

•

CTSgo for Windows 95 / 98 / NT 4.0

The program may be installed in German or English as desired.

For detailed instructions regarding the operation of this program see chapter "Windows Application
CTSgo" (Tabbed Divider 4).
