To manually update your DVR+(CM-7500) software, please follow these steps:

  1. Click on the link above or below to download the .str file to your computer
    https://support.channelmaster.com/hc/en-us/articles/200488325-DVR-CM-7500-Manual-Software-Update-USB- 
    a. Depending upon your computer, this file may automatically go to your
    "Downloads" folder.

    b. If after the software file download, you get a dialog box asking
    something like 'Do you want to Open or Save (Save To) 135R.... , do not
    choose "Open". Save the file to your desk top or a folder of your choice. 

  2. Transfer the .str file to an empty USB memory stick.

IMPORTANT: Make sure there are no other files on the USB memory stick. Do not rename the .str file or place it in a folder. A 2GB to 8GB USB memory stick works the best. However, we have heard of some customers that had to change USB memory sticks in order to successfully update the DVR+. We do sell the USB stick with the current software installed. $10.00. #CM-7500XUSB.

  1. Physically disconnect your WIFI adaptor and/or External Hard Drive. (If you are using one)
  2. While viewing live TV, insert the USB memory stick with the .str file into one of the USB ports on the back of the DVR+(CM7500)
  3. When the DVR+ (CM-7500) recognizes the software file, you will see a popup on your TV screen notifying you that you are about to update your software. Select CONFIRM.
  4. When the update is completed, (About 4 minutes) you can physically remove the USB Memory Stick. 

Although not required, we do suggest a factory reset after updating software. Complete this while the External Hard Drive and/or WIFI adaptor is still disconnected.
