  1. I have a RT7 model, and I want to change the channels 9 to 16. I write new values to device, but when I read again, my values are lost, and it shows the factory values.
    I change the values on channels 9 to 16, but always returns the factory values. This error occurs for all columns on these channels. Another example; I change the scan column to Yes on channels 9 to 16 and when I read the device, it returns this column on these channels is No.
    Please, can you help me? Thanks a lot.
