To manually update your DVR+(CM-7500) software, please follow these steps:
- 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. - 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.
- Physically disconnect your WIFI adaptor and/or External Hard Drive. (If you are using one)
- 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)
- 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.
- 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. Find that instruction here.
