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 update it.
1. Using your favorite Web browser, go to http://www.multitech.com/support/MultiModemII/
firmware.asp.
2. Scroll down the table to your modem model number.
3. Look at the firmware version number for your modem.
4. If the firmware version number matches the firmware version number found in “Step 1: Identify the
Modem Firmware,” your modem has the current firmware version, and does not need to be updated.
5. If the firmware version number is greater than the firmware version number found in “Step 1: Identify
the Modem Firmware,” your modem has an older firmware version. Continue with “Step 3: Download
the Upgrade File.”
Warning: The first digit of the new firmware must match the first digit of the old firmware, or the modem
may not work properly; e.g., if your current firmware version is 4.16, replace it only with 4.xx firmware, not
6.xx firmware.
