Appendix C – Upgrading Your Modem

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.

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 at the Multi-Tech Web site. If your modem already has the
current firmware, there is no need to upgrade it.
3. Download the upgrade file and the appropriate Flash Wizard for your modem.
4. Install the Flash Wizard and extract the firmware .HEX file 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 Wizard.
7. Restore your parameters.
