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.
