Procedure

Introduction

Flash Upgrade Firmware

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, either the manufacturer or the user can change the firmware as bugs are repaired or new features are added.

Multi-Tech System’s Flash Wizard utility can be used in a Windows operating system to update (flash) your modem’s firmware.

The Flash Wizard utility can be downloaded from Multi-Tech’s FTP site and is available on CD.
