The CDM-760 begins the firmware re-flash process. As files transfer from the User PC to the

modem, the list of files and their transfer progress displays in the transfer queue pane (at

the bottom of the screen). It takes approximately 15 minutes for all files to transfer. Do not

turn off the User PC or modem during this process.

On the CDM-760 Front Panel – Make note of the current Active Image on the SELECT:

Utility → Firmware screen:

Firmware Images: ActiveImage: 2

Info Select ( )

Then, on the bottom line, use the ◄►arrow keys to select Select. Press ENTER to continue:

Current Active Image is #2

Next reboot, will use Image: #1 ()

In order for the Image that was just updated to be ‘active’ the next time you reboot the

modem, you must select that firmware image to be the Current Active Image. Use the ▲

▼

arrow keys to select 1 or 2. (In this example, Image #1 was updated and is therefore the

required choice.)

Alternately, on the CDM-760 HTTP Interface Configuration | Utilities page, use the Next

Reboot Image drop-down list in the Firmware Image Config section to select Image1 or

Image2, and then click [Submit]:

Once you press ENTER on the front panel or click [Submit] from the CDM-760 HTTP

Interface, the modem verifies the checksums of all the files that are being updated:
