PORTABLE USB MODEM

Appendix D. Upgrading the

Modem

D.1 Introduction

Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory. Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are added.

Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few minutes by using the following procedures and the Flash Wizard program.

D.2 Upgrade Overview

The upgrade procedure consists of the following steps, which are described in greater detail in the following sections.

1.Identify the model number and firmware version of your modem.

2.Identify the current version of the firmware. If your modem already has the current firmware, there is no need to update it.

3.Download the upgrade file for your modem.

4.Extract the firmware .HEX file and the appropriate flash upgrade program from the file you downloaded.

5.Document and clear your stored parameters.

6.Upgrade the modem’s firmware using the .HEX file and the flash upgrade program.

7.Restore your parameters.
