How do you change channels on a artec dig to analog converter with no remote?

To change channels on an Artec digital to analog converter without a remote, use the buttons on the front panel of the device. Typically, there will be a channel up and channel down button that allows you to cycle through the available channels. If there is a menu button, you can access the channel list and select the desired channel using the navigation buttons. If your converter has a dial, you can also turn it to change channels.
